Ok guy I am going thru a GM Buy Back my truck is still over heating and still no fix had it reflashed too. I keep taking it in they wont even take it and look at it because they say there is no fix. So i am going this route I need all the guys that are having over heating issues and say I. Please only post if you are having over heating issue so i can print it off and so they cant say I am the only one I hate when they say that. This post will also help anyone else going for a buyback.

I am have the over heating problem as well and GM is saying the very same thing, I am the only case they have heard about so far. There is no GM employee on this earth that is willing to admit what is going on. There must be a BIG gag order on this issue. I have talked to several different GM customer service, GM service advisers & even a couple GM service techs. They all say I am the first person that they know of to have overheating issues.

my dealer is very aware of the problem , they are building a radiator as we speak , and are using my truck as a test bed for Hood/rad/fender mods ect. to attempt a fix ,They may not be in the complete right direction with these ideas but its a start. GM in general is aware of the problem and are likley being closed mouth as to a fix as there is not one yet, but I can say they do know because they are trying to fix mine.

Please post what your symptoms/problem is. Is it only while pulling a load or what? Thanks.

put me down as one 3500 drw that overheats every time I try to pull a load up a hill this is the most pathetic excuse for a 1 ton truck I have ever had. My dealer is aware of the problem and and has told me that any attemp by me to modify any part of my truck will result in my warranty being voided by them. Oh by the way anybody want a really good deal on a 2004.5 white Lt I mean a really good deal cause I'm buying a
DODGE!!!

A Dodge, did you say Dodge? -:t -:t -:t

Well I guess you really don't have any other choices.

Before you buy the Dodge check out the prices for keeping it maintained.... My friend has a new one and they are making him change the rear end oil every 3000 miles... 150.00 a pop.... He is going to sell his because he can not afford the maintance.... Just a warning, check it out first...

$150 a pop? why the hell doesn't your buddy do it himself? if he was close to me, i'd do it for $100 a pop.

gasket=$10
oil =$30
1/2 hour labor = $60
:D

sorry to get off topic by the way

I have two seperate employees one has a Ford One has a Dodge both are 3/4 ton trucks Both can and do pull my trailers that My beloved Chevy cannot as for maintaining a dodge his is 1 year old bought within weeks of my chevy he has as of today no problems and no maintance issues that I haven't had oh and he has 32000 trouble free miles I have 13000 and wonder if it will go to 30000 I pull every day and this truck can't hack it.

Swatkins no offence but your friend is a sucker if he goes for that

your truck may have problems but that is NOT the case for all chevy's. ALL brands have troubled trucks but that doesn''t make the brand junk! I have a 2500hd 2003 duramax and I have no problem towing 10 - 15,000 pound trailer when 100+ and never going slower than the speed limit and the temp guage never moves up to 210 rarely does the fan even kick in.

Yours is NOT a LLY dmax - so the problems with overheating do not apply to you!

The buy-back is a long and drawn out process. It took me months of talking and talking and talking. Stay focused..

I have an LLY and have not had any overheating problems, I guess I'm the only one?

I tow 12K with not a lick of problem.

Huntsalot states "Please only post if you are having over heating issue so i can print it off and so they cant say I am the only one I hate when they say that."

Doesn't appear that Huntsalot is looking to rehash the LLY overheating issue, just needs for those that have actually overheated to post on his thread.

Huntsalot, you might go back to your original overheating thread and PM the guys that posted overheating conditions. JJ

Mine is overheating while pulling at altitude (5k+) with a 10k load.

Mine is overheating while pulling at altitude (5k+) with a 10k load.

Exactly what I noticed driving in Arizona and New Mexico above 5k feet - fan came on every 3 min. without pulling any load at all!

I am still thinking the boost is too high with altitude and therefore produces too much heat (and overheats).

dealer is making him change out his rear diff fluid every 3000 miles!! something fishy there!! i have 04.5 dodge 2500 with the ctd. my owner manual says to change every 15000 miles.!!! plus, if you switch to synthetic and don't tow alot of heavy loads,etc. you can get way more than 15000 miles out of your diff oils. also, my dad has an 03 truck like mine- he has 83,000 trouble free miles. i have 27,000 trouble free miles. we have had absolutely zero mechanical problems! no squeaks, rattles-nothing!! only a tsb on the driver side door weather stripping and one reflash for rough idling when cold.i was hesitate going to dodge-from all the horror stories about them in the 80's,etc. all that i can say is, i am very happy with their product!!

My 04.5 was overheating and I proved it to GM beyond a shadow of a doubt with their data recorder and they bought it back. I started complaining last July and it took until late January to complete the "goodwill" buy back.

My new '05, which I ordered in December is much better. I left Los Angeles a few days ago and I am now in Lake Tahoe. I went north on I-5 near Castaic with no visible temp increase (stock gauges), outside temps were not that hot when we started out our trip, mid to upper 80's. I went north on 99 through the Central Valley with outside temps above 95* with virtually no increase in running gear temps. Only one time did my engine temp rise slightly above 210* when I was passing a Semi near the top of the Castaic grade, and my tranny never went over 190*. Now I have a few mods to this truck that my 04.5 did not have. 4" exhaust, Hypertech, fingers stick, egr blocker, MikeL cooler, and the kitty went to the animal shelter. My trip is not over but I really like what I see at this point. Good luck to you!!

BTW, what State do you live in?

I pull a 15000# Mobile Suite 5er and have no problems with temps, but my truck is as it left the factory!

CFK2 aside from a boost gauge and pyro mine is also stock have you been to the mountains? No slam to Chevy by me I will keep this truck but am buying a Dodge to do the pulling that my work requires. The wife can get the groceries with this one.and will pull a small 3500 lb cargo trailer with my 3500 DRW LT it can handle that!

I have two seperate employees one has a Ford One has a Dodge both are 3/4 ton trucks Both can and do pull my trailers that My beloved Chevy cannot


what are these trailers and why can't your 3500 dually pull them when the ford and dodge can?


oh and he has 32000 trouble free miles I have 13000 and wonder if it will go to 30000 I pull every day and this truck can't hack it.


why can't your chevy hack it? what's the problem?

rustynuts; I pull two different gooseneck dump trailers that weight 13,000 and 15,000 loaded and a 5th wheel that has a travel weight of 13,500 to 14,000 the problem is I can't get out of the valley I live in to get to the dump or to the camping in the mountains without overheating in the summer. Another problem is that now you can buy a new truck for a great price I won't be getting cr$p selling a 1 year old truck with 13,000 miles on it. It will be interesting though to do side by side once I get my Dodge

One thing to look at guys is that it appears that all the overheating issues are on 04.5s

Does anyone have a 05 w/ overheating probs?

I got a 2004.5 and it's never over heated.. I pull trailers every day. from 9,000 to 47,000 total weight.. I guess I got one of the good ones.. 60,000 mile on it now.

I live in Missouri,the hills hear are steep and I think the only thing that saves my truck is that their not very long.I pull about 8500 # travel trailer,the fan stays on most of the time and the temp gauge gets up to around 220-230 or so by time you get up to the top of the larger hills.Makes me wonder if it can handle a trip to the mountains that I hope to go on soon.Just put on a 4" mbrp last week and I hope that helps get some of the heat out from under the hood.

My overheating 2004.5 LLY is bone stock, always has been. It only overheats when I pull my fifth wheel toy hualer. Truck and trailer combined weigh 20,700 lbs ready to travel and camp. (I weighed it once) The one time late last summer when I reported the problem to the dealer I was told that "GM" was working on the problem but there was no fix yet. I guess cold weather came, the problem went away for the winter and no fix was looked for or found. Last weekend (July 4th) I towed the trailer to the mouintians here in Arizona and at every major grade got the "engine coolant hot" warning on the DIC. I turned the AC off at the bottom of every grade. Outside temp was only 90 degrees.

One thing to look at guys is that it appears that all the overheating issues are on 04.5s

Does anyone have a 05 w/ overheating probs?

Yup.

My 04 lly was bought back because of turbo, steering and overheating problems. My 05 however has been great and temps seem to be in check. I am not brand loyal as I have owned them all. my company has owned 3 dodges in the last 10 years and they same applies to each. Good motors, tranny bad, and rest of truck nickled and dimed us till we replaced them. Everyone has different luck.

Out of curiosity, when you say it overheats, do you mean the temp hits 260 and you have to pull over? Or does it just get a lot hotter, say 235 or so? If thats the case, then I might be in the same boat. Pulling an 8k travel trailer, any kind of hill and the fan kicks on. Hit the grapevine here in so cal, heading south, and I am guessing maybe a 6% grade and the temps jumped to the line below 235. The fan never shut off. Hope thats what you are looking for. Jerry.

I have a 2004.5 LLY and it overheats. service manager and GM are well aware of it, and have been for about a year now. Don't let em BS you, GM knows of the problem. I'm waiting to schedule the hood/radiator/fender fix, and my SM supports me doing a buyback if it doesnt work.

I am in the same boat as Jerry01. it gets to 230+ very fast on any type of grade towing 12K+. Mine is lifted but it looks liek it doesn't matter as it is happening on stock trucks as well.

I purchased an 04.5 lly in April 2004. Within the first 6,000 miles I had major overheating problems when pulling a four horse trailer up a 4,000 foot hill in Arizona. I took it to the dealer, who replaced the fan clutch, told me everything was fine, and implied that I was the only one they'd heard of with this problem. The problem has continued and now, with the summer heat, it is unsafe for us to haul our horses with this truck. Our 2001, 2004, and 2005 D-max's have pulled the same trailer under the same conditions without this problem. The last time we brought in the vehicle, the service writer told us (we believe accidentally) that GM in fact was aware of overheating problems. The service manager, Randy, at Lamb Chevrolet in Prescott AZ finally admitted that overheating was a "concern" of GM, but not a "problem." We told the dealer it is a "problem" for us! Randy stated that GM engineers are working on a fix, such as hood mod or other air flow changes. We have escalated this to GM. We feel GM and/or the dealer has been deceptive about this, which has affected our rights under the law. Please reply if you have had similar issues.

Norm

If you guys have not voted in the OVERHEATING LLY'S - 10,000lbs or MORE (http://www.dieselplace.com/forum/showthread.php?t=37580) poll then please do so.

I am tired of GM dragging feet on this and plan to present the poll to GM Powertrain and if they don't take action that can be seen by us then it is time to get the media involved to try to force them.

Whats right is right and they have sold and are selling a product that doesn't perform as promised.

GM in michigan wasn't aware of it last year when I started ambushing GM guys via the phone, then last year they really wouldn't admit it, this year since march they do and claim to be taking action to fix it. I call BS and say fix it faster, quit humping the dog, admit there is an issue and put some resources on it.

I have seen the issue and have no idea how the hood and fenders could fix it. unless air flow is that greatly different.from what I read it sounds like even stock no trailer over heats. has anyone taken the vehicle data recorder on the truck and taken a snap shot for the techs??? i can not see it as an engine issue. I would have to say its a programing issue. Is this only a southwest issue?

Nope- mine did it comming home for the west this past weekend just east of Lacrosse on I90. 68 mph , 2th mile after the down shift temp was 230 and then came the end of the hill, higest I have gotten is 235 before I backed way out- my 01 you never had to back out, just :grd:
Marty

How many of the last few year Dodges with the new cummins motors are overheating??? I think a few of you would fail a drug test on some of your statements on Dodges maintence costs, my buddy with his 2004 spends lot's less than I do on my Dura'clunker. I guess I'll give you the benefit of the doubt.....Nobody's perfect.....

I have a overheating problem with my 04.5. I had to pull over 6 times on my 3200 mile vacation. I hit 259 degrees. I called Gm and they told me I was the first to report a problem. I went off on the guy!!! I told him to save it for someone that would believe his bull sh__ _ !I wish they would face up to the problem. Can someone tell me What you need to do for the buy back?

that sucks, gm better get their **** figured out, that lb7 never had this problem, you would think it would not be that hard to figure out the difference, with the two

Just a note for some of you , there is NO BUY BACK, GM will look at any and every case on a singular basis ,it is not easy to get a MFG to buy back a vehicle so don't get your hopes up it's a long drawn out process and a very low % are actually repurchased , If we hang in there and a fix is generated then who wants a "buy Back" if they try and fail then you are on much more solid ground for a possiable solution. I hate to be a party pooper , but I do hate to see people saying thing like "I am going to start the buy back" like its just a matter of ask and they say OK....... Believe me I have reason to say this and the situation I had (not with a Chevy) Makes the overheat problem seem like nothing and I was never taken care of ...NEVER. My situation lightend my wallet by about a $50 thousand+ and took 5 years and I still was not satisfied , I finally settled to close the money pit and sold the Vehicle at an additional loss of $26,000. I am not saying give up , just I have more patience now as they are trying to remedy the problem.

I don't think anyone will get any kind of byback from GM unless you have a Lawyer. I also would guess that when there is a suloution to the overheating problem it will be someone from these forums. All thier Engineers live and work in Michigan where there is very few mountians and the temps are low. It doesn't effect them so it's not important.

Apparently you are unaware of the Proving grounds in Arizona.
I really dont think that the fact that GM engineering being in Michigan has any impact on this issue getting addressed.

I thought GM closed the Mesa one to move to Mexico?

All the mfr's do extensive testing all over the US prior to a vehicle release. They disguise the vehicle the best they can, and put miles on them in varied conditions.

Why didn't GM catch the heating issue? Good question. I think the answer lies in the fact the overheating is not present in 100% of the vehicles. Makes me think they changed something like a parts vendor, tuning, etc, after the testing was done when the vehicles were in production. Could be something as simple as a coating change on the radiator, or as complex as changes to the cylinder head cooling passages. Dunno.

I am a tech at a chevy dealer and honestly have never had anyone complain about overheating only the smaller trucks with plows are giving us trouble..

Hey Mikek996, no offence here, but how many 15+ mile 6-8% grades are there in Mass. that one could pull a 10k load up when it is 110+ outside?

:exactly:

Yep, out West we have long steep freeway grades at high altitude and high temps. Even passenger cars run into heat issues. But a diesel pickup built for towing should have enough reserve cooling capacity to deal with anything you can throw at it at the advertised GCVW in stock configuration. So far both of our trucks have been exempt from the problem, but I don't tow at the GCVW limit.

Hey Wallbanger, Don't buy a Dodge you will be VERRRRY dissapointed. I traded my '05 3500 in for my D-Max. Dodge is a nightmare on warranty alone. They probably employ people to find ways to void warrantys. Oh yeah, their truck is a POS as well!!!! Trans= junk, intercooler= junk, motor (w/mods) = gutless. Trust me, this is a bad truck. I have to say that my '04 PSD dually w/ few mods pulled my 15000# trailer 2 times better than my new LLY, and 5 times better than my Dodge. I guess I should have never gotten rid of my Ford. Oh well, hindsight!!!

I do and I only have 1500 miles, bought it just a month ago. I had the VDR but also
video taped the pulling session going to payson out of scottsdale, due to the fact
you only get four tries at it, I have it on tape overheating and the dealer still doesn't
believe me.

Ask your dealer to provide you a data recorder, and if that dealer won't find another dealer. Also, call the customer service number and request the same.

I went through two buy backs Ford and Chrysler - The stinkin dealer doesn't have to believe you, just pretend they don't exist. In Ca. if you take it in three times for the same problem, and not fixed, it's a lemon PERIOD. With Crysler the dealer jerked me around with the ole "could not duplicate" ( I think they have that printed in their wallets like the cops have the Miranda rights, anyway each time I said thank you, and returned the next day with teh same problem, agin the "can't duplicate" I smiled left, returnrd the next day "could not duplicate" GOTCHA. That's three times and no fix. I typed my lemon law letter to Corporate, they wanted one more chance I said nope you had three chances, but I gave in anyway, they called a month later and said order yourself a new one. Took about a month and three certified letters.
They purchased all the goodies I put on the vehicle, tires radio, and gave me full retail, even though I paid below sticker.
So there IS a buyback per the law, it's simple fix it, give me a new one or give me my money back it's that simple.
Can they Jerk you around, sure they can. Ford took three years to give me a new truck, so what - I drove the truck for free for three years, and got full credit for it, plus a new vehicle, plus they paid the sheister lawyer fees of 60K for Jerking me around.
They have Lemon laws for a reason , check your State.
Now for me and this rig, I'm doing the same thing taking it in for overheating, it won't be fixed, I'll do it two more times, and then the fun begins.

They won't be able to fix it, so the lemon law is a lock for you.

.

Problem is - steam coming out from under the hood, stuck on the side of the road - driving a GMC is still better than driving a working Ford or Dodge.

I live in western Ma and have pulled the truway between exit 3 and exit 2 up Westfield Mt. and overheated 245 ECT. I have had my truck into the dealer twice with no results. These trucks will overheat if pulling 12,000 LBS. regardless of where in the country they are

Just to bring you Folks up to date; GM has not closed there Az Proving Grounds. There was a plan a couple years ago to move to Mexico but GM was unable to get Mexican approval so they`re still here still testing. All of the Majors have Testing Facilities here in Az. It`s very common to see test vehicles on the road wrapped in camoflage. I own a `03 Sierra gasser and all this O-heat is keeping me from jumping to a D-Max. I think if we were to think over the recent history of Gm they have built a share of Dogs= Vega, Monza, Cimarron etc. The only way this will be resolved is by keeping GM under the Gun. Another Website called Rip-off Report has a lot of advice and notes the BBB is worthless along with local TV, Radio and Print media. The Reason=they don`t want to Burn their Advertising Revenue.:cool:

JJs PowerStroker? JJs CumminRammer? Uh, just trying out potential new names! lol Not yet! JJ

OK, so maybe after a lot of grief GM will buy one or two units back. But for the vast number of us, they won't unless they have no alternative. Forget it. Let's figure out what might work. The new '06 models have a different stack arrangement, different fan shroud and different inlet. Course we don't know how this is going to work out yet, but let's say it does. How big of a deal would it get to be to replace the fan shroud and see if that helps...

Maybe it's a doable solution..

Before you buy the Dodge check out the prices for keeping it maintained.... My friend has a new one and they are making him change the rear end oil every 3000 miles... 150.00 a pop.... He is going to sell his because he can not afford the maintance.... Just a warning, check it out first...

Steve
That is so far from the truth.. Changing the rear end every 3000 miles? Someone is stroking you or your friend dude. There is nothing in the service book that even comes close to that requirement.

Wow, I just finished a trip to the Mohave desert this past weekend in my 03 duramax. I towed my 13,000 toy hauler and per the outside temp gage, it was 117. On flat land the edge monitor showed 195, climbing a few grades it got once to 205, but the fan kicked on and it immediately dropped to 199. My brother just got a 05 dually, and towed a whopping 3000 lbs trailer to Texas, and he reports continual 230 degrees plus... Maybe those new heads are part of the problem? Poor water jacket designs??

I hate to sound like a Duramax fan club member but I'm pretty happy with my 05. I averaged 14.5mpg pulling 5,500lbs of Camaro and trailer at around 75mph.

FWIW I was very pleased with the Super Duty I drove, but bought this one because of the discounts.


I remember reading about 7.3 Ford owners wanting a "buy back" because of pin holes in the coolant passages.....

And if you force a "buy back" on more than one vehicle from more than one manufacturer that tells me something about your maintainence and driving habits.

Well, I finally broke my new 2005 LLY in for the first 2k miles, hooked up my 7000 lb toybox and towed it for 200 miles at a moderate speed from San Diego to Yuma, AZ, the fan clutch keep kicking in, even at 50mph and slowing me down. The temp it at 220 - 230, but the fan clutch only goes off for 5 minutes at a time. Every time we went up a hill the fan kicked on. The truck is completely stock and I'm not happy with it, any suggestions?

How are my driving habits? Im sure you know alot about me you sound like a service person at the stealer. Like im the only one having a problem. 2nd on my 2 fords I went thru 30 alternators and Just like GMC they said I was the only one but guess what with the Internet I found that there were 1,000 having the same problem. P.S. I change all my filters and oil every 5,000 miles. How often do you change your filters and I mean all filters? And how often do you change all your fluids?

Just so you know its up to a arbitrator. Not up to GM they called me and said they wanted to give me 100k warranty plus as long as I own the truck free oil changes and tire rotation. I said how does that help me from overheating. So I said no and I will see them with the arbitrator.

I have and 04.5 GMC and pull a 26 foot 5th wheel. Just got back a couple of weeks ago from a 3600 mile trip out to Colorado and it never over heated. It stayed on 210* and fan would come in and out some but not what I would call excessive. This was with and without a tune, trip average economy was 11.8mpg. Best tank 13.8 and worst was 10.2mpg. Colorado will test a truck so I guess mine is OK.

I'm not belittling anyone's problems and I have yet to find out whether I have problems or not - I've only had my truck a month. I am very concerned about these issues. I haven't pulled anything yet, and I haven't been up any hills. That will change next week. I have checked the lemon law in my state and it's 12 months, 12,000 miles. I would need to make three service visits in that time.

But in the meanwhile GM is losing $1B per quarter. They're not going to buy back a lot of trucks, even if they have to declare bankruptcy, which is not out of the question. It would free them from their pension obligations. Other firms have done it.

It's realistic to expect them to publish a TSB and maybe do some retrofitting to band aid the problem. First they have to know if whatever mods they made to the '06 fleet have been successful. They'll only want to do the TSB once, and they'll pick the cheapest route that solves the most number of problems for the fleet. Some of us will never be satisfied with the outcome. (That's a fact, not a personal comment.)

I hope that you are one of those whose ordeal comes to a satisfactory conclusion.

Best luck

Ed

Good points bettered. The Silverado is GM's golden egg at tops in sales for several years now. So the incentive is there for them to find the fix, fast! Maybe the changes on the 06's will do the trick? If so then a retrofit to any overheating 04.5's and 05's should be fairly simple and inexpensive.

This is an emotional issue, when emotions run high its very easy to unwittingly step on someone else toes, so I'll apologize upfront for anyone that I may offend. For now I'm sticking with my truck and hopeful a fix is close. If something solid doesn't surface in the near future I'll have to make a decision to keep it or trade it.

The overheating solution thread has some really talented and smart people working this issue, moreso than we had on the original overheating thread. They're going at each other, but on a technical level versus this truck and that truck like most owners do.

LanduytG, glad to see you had a successful trip, very respectable mpg's to. JJ

Just as a confirmation, I drive by the Mesa proving grounds all the time - it is still very active, I see wrapped test vehicles all the time - many of them towing trailers and running up hwy 87 through the mountains. I don't know what elevation it gets up there, but I think the Mt Ord summit is 6000 or so and that is a hell of a grade going up it.

GM has every oppurtunity to test these vehicles in hot, with grade, loaded conditions.


Just so yall know...

How are my driving habits? Im sure you know alot about me you sound like a service person at the stealer. Like im the only one having a problem. 2nd on my 2 fords I went thru 30 alternators and Just like GMC they said I was the only one but guess what with the Internet I found that there were 1,000 having the same problem. P.S. I change all my filters and oil every 5,000 miles. How often do you change your filters and I mean all filters? And how often do you change all your fluids?


I didn't mean to step on your toes even though it sounded like it.

I've not changed any fluids or filters yet. I've got about 1,400 miles on the truck so far and haven't done anything but put fuel in. I'm not looking to do much. I use it as a daily driver and tow a 5,550lb trailer on weekends. I'm not working the truck that hard, and sure hope it lasts a good 400-500,000 miles. Which with proper care I'm sure can. My father has gotten 300,000 out of a handfull of GM gasoline engines.

If that's the case, they must not be testing the Duramax's! Im in Mesa as well and am curious if your fans always running? Im tempted to just disconnect my rive shaft and let the darn fan pull the truck around! Ill be pulling my first 10k trailer next weekend and am hoping I don't have these over heating problems! Heck mine's already got hot just sitting in the shade!
:confuzeld

I would definately question GM's hot climate testing!

Snapper,

I personally saw a test fleet back in July of '00 going up to Payson pulling some pretty good sized loads. I passed them in my '99 Dodge CTD.

I was meeting my parents for a 'dog exchange' at the Casino just south of Payson. The test fleet pulled into the gas station there while I was waiting. There were at least 6 Dmax's. One 3500 was pulling a big gooseneck flatbed with large concrete blocks to simulate a load.

The big question, did they repeat those tests in '03-4 with the LLY? From the looks of things around this site, I'd say NO!!!

From the sounds of it, Id have to so no! :nono: I just hope Im one of the lucky ones that has no issues......:ro)

We too have been having overheating problems with our new '05 LLY. We didn't buy the truck to have problems nor do we think that we have to be the ones to fix it. When we took it to the dealer for a recall on the brakes, we told them about the overheating and they said it's normal. Add my name to your list of rather unhappy customers. Anyone here own a new Powerwstroke - how do you like it? Nils

I have 2 Friends, 1 w/ 04 Exc 6.0 and 1 with 05 6.0 Dually- the 04 has has 2 trans in 18k and the dually has had 3. not sure but don't think I want that either.

If GM wants to test their rigs, or ant mfg for that matter - cmon out here to Palm Springs Ca., it's been 116 - 123 all week, and we have some long high mountains to make any truck puke antifreeze.

I think that once a truck heats up a bit the first time, human nature is the next time it gets close to hot, we step on it a bit more to see if it will do it again and so on and so on. mine had a fuel knock, and every time i drove it, i looked for that noise. I say when hot, back off her a bit, it makes a big diff.??

I drive for a living and you just told me to make less this week because I have a higher truck payment to make, and GM can't figure out its own problems. NOT!

I had a 6.0 '04 PSD. The tranny is weak when you put power to it. However, the design and operation of the torqueshift is far superior to that of the Allison. There is a fix for the Ford tranny, and as for overheating.....they don't!!! Oh by the way, they out pull any D-Max I've seen with mods!!!We too have been having overheating problems with our new '05 LLY.

I have A 2004 F250 6.0 with 40000 miles and no ploblems (yet) Temp gauge hardly moves going up hill pulling A trailer.

My travel trailer only weighs 6400#, well within the limts for this truck. This is the same trailer that I pulled with my 02 1/2t Suburban and 03 1/2t Avalanche. After 6000 miles with the other 2 trucks and a lot of summer driving from MI to FL, down the east coast or I-75, not ONCE did the fan even engage on either of the gassers while driving down the road. NEVER saw the temp gauge go over 195 on either truck while pulling this trailer.
The first summer heat pull in heat between 85-90 deg outside temp and the D-max is howling away on anything that aint flat. The only time it got hot was on the Zilwaukee bridge, it popped up to 210 and went down as soon as the fan kicked on. While I dont think my truck is going to melt down pulling this trailer, one of the BIG reasons I bought it was for a trip out west that we have been planning for years. I really didnt think I wanted to do that trip with a 1/2 ton gasser..... now....
My wife is busting on me now over the extra $6k I spent on this truck for the D-max. "your Avalanche never did that" and she is right.
I am hanging back taking it to the dealer, knowing that they wont do anything other than waste my time.
This and the other threads are my only hope.

Has anyone had a problem with a stock 05 Duramax overheating?

Stock
-no aftermarket items
-same tire size as factory/ larger tires affect gear ratio

Overheating
-210 is normal temp for the 2005 Duramax
-also says it is normal for temps to go up to 240 and it is not hot until 260

No bashing please, just bought mine and want to see things I should avoid.

Thanks

Mine was stock when it happened with the exception of a 5" no kitty exhaust, which would do nothing but lower EGT's.

When the DIC says engine coolant hot, and the Ally's temps are at 230* and climbing, I don't think I would consider that *normal*. That is when I pulled off the road...

210 is NORMAL. I'd be surprised if a 6k trailer will heat it up. The guys who are getting hot are mostly high altitude, steep hills, hot air, and towing over 10,000lb.

Mine is ANSOLUTELY stock - Stock fluids etc, with only 800 ,miles on it.
Mine went to the red zone, till I slowed down let it go more to th enormal side, if I pushed it or went up a hill the temps climbed right along with me.
Tranny temps on the high side. No codes, no coolant hot mesages on mine.
So you see there is nothing to avoid - it's the truck not the mods.

Oh , and my altitude is 228 feet below sea level at the starting point ( Salton Sea )

Does your 5" no kitty exhaust increase HP? Yes, then is makes more power and will produce more heat in the engine when using this add HP. I have read every post and have yet seen anyone that has a stock and I mean stock truck with a overheating problem. So please only someone with a stock truck please answer.

Thanks

Read my post - ABSOLUTELY stock, damn near the factory fuel in it.

Read Kendall69 post.

Obviously you do not understand the relationship between EGT and HP, but that is OK, you're a newbie. The point is this, 100% stock trucks are overheating, and sometimes worse than ones that have had mods.

Sorry.

How fast were you going? First 500 miles at 55 Mph with no trailer. First 500 miles towing a trailers 55 Mph. Engines will produce more heat during breakin.

Thanks.

What I believe to be normal is 195 deg (which I believe is the thermostat rating) anything over that tells me that the cooling system is not adequate. In my opinion the fan should never engage while on the expressway with that light of a trailer.
This is the 10th new Chevy truck I have owned, in all those years I never had a single one run any hotter than the thermostat rating.


Scott

Yes I do but since you feel that insulting me will answer my question then tell me what you know about EGT and HP?

Speed between 65-75 after 500 mile break in. Break in was under 55 varied speed for the first 500 miles.
Empty No overheating, with camper, overheating.
If you not going to haul anything or use a camper you should be fine, and I don't think it will over heat.

Read the manual. 2005 210 is normal.

Again read the manual. First 500 miles towing a trailer max speed 55 Mph. This is in addition to the new breakin of 55 Mph solo.

UPSp,

You've obviously got this all worked out, so why are you bothering to ask us?

Lowering EGT's has nothing to do with a diesel increasing output. Does it allow you to alter the amount of fuel being injected or timing to increase output? Yes.

But then again you knew that, right?

My Corvette runs 230 deg from the factory. Idling.

My GMC runs about 200, and the 05 runs 210. Unladen. Idling.

Until you climb past 210, you are not even using 100% of your cooling capacity yet. The thermostat is still partially closed. Once you move past 210, it climbs slow but steady. Until you hit about 245, nothing is abnormal or wrong.

UPS, couldnt disagree with you more, what page does it say that ?

Again I want someone to reply that has read the manual and understands to respond. You don't have a stock truck. I bet you have larger tires also.

Ugh, actually, they are stock.

UPS, dont see what you are reffering to, could you give me a page number ?

Assuming it does say that,
Why does it run 195 till I pull a grade ( a very slight grade )
with a trailer thats about half of what this truck is supposed to be able to handle
All this with an ambient temp between 85-90 deg, there certainly are hotter, hillier areas of this country than mid Michigan.

If your truck is not having any problems, thats cool, I am happy for you.
I dont understand why your are peeing on others campfire. The problem is legit, get over it.

Scott

Sorry Scott I don't have the book with me and I hope that you didn't damage anything. My temp sits just a tad bit below the 210 mark when I drive solo. Each guage will read a little different and all I can tell you is what I read in the manual that 210 is normal. I guess one could go to GM and ask them what Thermostat temp go into the truck. Try reading the duramax supplement book that came with the truck. Remember that these engines are very tight and this produces more heat until complete breakin.

Thanks

In the winter, my truck will never get to 180 deg unless towing.
In the summer (it's 100 deg today), it will sit at a stoplight at 210. It takes a LOT to move that needle past 210 though. Try getting it to 215. Bet you can't. Not in Michigan.

I spent a whole afternoon reading the manuals when I bought the truck back in February. Towed the trailer to Florida (after 1400 miles empty for break in ) and it pulled like a champ. other than the poor fuel mileage (which I attribute to it being tight) I couldnt have been more pleased.
I agree on the gauge discrepancy, my wifes Trailblazer shows it runs 210 all the time. My D-max runs 195 when empty no matter what the temp outside.
The problem I have is that my wimpy little half ton had a better sized more adequate cooling system than this truck, I think getting some cool air in from the outside instead of pulling it from the underhood area is the first place to start. Look at an M2 Freightliner if you get a chance, they pull through a duct to a opening on the left side of the hood, it doesnt look all that hard to design.

Scott

I am not trying to pee on anyones campfire. Me and my wife are looking at a larger trailer and I want to make sure this is a problem with the truck or the mods on the truck. I can understand real easy why yours got hot. A tight new engine will produce alot more heat then one that is loose and has some miles on it.

It went to around 215-220 pulling the Zilwaukee bridge the first time I pulled in summer heat, 90 deg, 65 MPH. my gasser never budged on that hill.

UPS my advise is for you to go ahead and buy that big trailer and pull it wherever you like.

If you hit 220 towing 6k in 90 deg weather, you probably have one of the "problem" trucks. While 220 is not enough to report to the dealer, if you were towing 10k or more at 100 deg out west, you would most likely hit the warnings on the DIC.

I Just a simple question for anyone that has a stock duramax that has overheated.

They say you meet the nicest people on this site.........-:t

Your manual might, I dont see it in mine.
plus that statement doesnt answer the other issues that I brought up.

Plus.... Mc Rat has agreed with me, now I have some cred.

Thought I needed to lighten the post a little

forgot to add the truck had about 7000 miles on it at that point, now at about 8500

They say you meet the nicest people on this site.........:lol:-:t

LOL

Heres something to ponder from my personal experience.
In 2003 we took delivery of a Freightliner FL60 with the 280hp MBE900 diesel (a collaborative engine built by Mercedes and detroit and used in Europe widely) This truck was before the change in the EPA regs and had an approx 700 sq in surface area radiator. The next 2 trucks we took delivery on were the M2 Freightliner (the FL60 replacement) Mechanically the same truck, except that the new regs forced them to make changes to the MBE900. The new trucks actually had to have a 4" taller cab mount due to the fact that they have a 1000 so inch radiator surface due to the EPA/CARB changes.
Apparently the thinking was that the new changes would produce more heat and require a bigger radiator, something I doubt that GM took into account.

Scott

Man, I haven't come across that in quite some time. This potential overheating issue is a tough pill to swallow for some...

Maybe it is time to just get a FL60 and be done with this whole thing!!!

Peace.

Does your 5" no kitty exhaust increase HP? Yes, then is makes more power and will produce more heat in the engine when using this add HP. I have read every post and have yet seen anyone that has a stock and I mean stock truck with a overheating problem. So please only someone with a stock truck please answer.

Thanks

Maybe you should read some of mine. I overheated bone stock on 3 differant trucks. Adding power seemed to help.

I'm running a totally stock LLY that can hit 230 easy with a 10Klb. trailer. This is in 70-80 degree climate with average mountain passes. I KNOW this truck will overheat going cross country fully loaded.

Previous to the 05 LLY I had a 03 LB7. Pulled the same load on the same routes. The LB7 performed flawless and was also stock except the muffler.

I see no need in arguing anyones point. The facts are GM incorporated some changes into the 06' that address the very issues some of us are having. I would be curious to hear somones answer as to why they did that, if infact it was not to address cooling issues.

Funny thing, cooling trouble, we got no stinking cooling trouble, but yet changes in cooling and air intake have been made. WTF??? I am waiting for a 06 to hit my dealer, then after I look real close I am calling a meeting with the service manager, and the zone manager and asking if they are fixing or replacing my truck, went in for the 2nd time today (on record, 5/6 off record, ya I was dumb and didn't have a RO made but hind site is 20/20) Had the add'l spoiler done today and plan on towing Sunday when temps are to be in the 90's, see if it helped but if the trip home was any indication I got maybe 5 deg drop. We'll see.

I have the truck parked and is not being driven. I will be following the same route that you have outlined as well if GM does not issue a TSB and move on this issue.

I guess mcmuffin has never been in Michigan in the summer, its hot hot hot and sweaty.. Which makes engines run very hot with all the humidity.

Peace.

Thanks for the compliment !

BTW.. they dont make FL60's anymore, I was attempting to note that GM isnt the only company that had to deal with the EPA/CARB changes, I think others handled it better.

I wonder what a lower thermostat will do?

I wonder what a lower thermostat will do?

Possibly give you a tad reserve capacity before you start up that big hill. If you're already over the thermo's full open temp, then you are riding on the coolling system's cooling ability aleady.

I haven't "overheated" yet, but I know mine's a hot one. I can hit 220 completely unloaded driving in my normal area (hills and twisty roads). Fan runs most of the time I'm not going down hill or on the fwy when temps are 85+. I have never had any vehicle that depends on the auxillary cooling fan like this truck does. I'm waiting for a fix, 'cause I like the truck, but I'm leaving it in stock engine/drivetrain, etc. form so nobody at the dealer on up has an out.

Meanwhile the "for sale" sign came off the '99 PSD and it's back doing the real work -- which it seams quite happy to do...

I find it curious too how the '06 has so many of the potential fixes that have been written about on this forum, and if the LLY didn't have problems getting hot, why'd they implement so many cooling mod's in '06?!

The overheating is real. My dealer admits it, says GM is very aware. In fact they told me they are testing in phoniex, Az. coming up Hwy. 17 to Sunset point to test them. My dealer says GM is saying altitude and heat are the most common factors (with some load, doesnt have to be 10,000.) They have pulled my 5th wheel with my 04.5 and seen the results. They are buying back my truck, because at this time they dont know the fix. My big concern is all this extra heat, whats it doing to my tranny and motor over the long run? They told me MAYBE GM will exstend the warrenty once they get a fix. No thanks. I ve always liked my truck except for the heating. In 2 weeks they get the 06 Duramax. They are going to give me a deal? We'll see. I hope its a better one.

please participate in a new poll HERE (http://www.dieselplace.com/forum/showthread.php?t=38875)

Hotmax- who is your dealer? Who is your area rep.? Our area rep. supposedly rejected our buy-back without ever speaking to me or looking at the truck. We are in Chino Valley and our dealer is Lamb Chevrolet. GM told us today that they won't buy back our truck- "service dept. can't re-create overheating" - and GM as well as our dealer STILL won't admit to us that there is a problem ... yet, they say in the same conversation that they are working on a fix. Gee, on a fix for what? I asked if they really think the public is that stupid. Anyway- our problem happens when we haul our 4 horse trailer up to Sunset Point- and we are not subjecting our horses to that again, with a possible overheating problem! How many people are still out there with this problem? ... My girlfriend is a lawyer and would like to know how widespread this problem still is. Perhaps a class action? In my opinion, the dealers'/GM's failure to be forthright at this point is deceptive. Please contact me directly at norm@elementaltech.com.

Norm

We too have been having overheating problems with our new '05 LLY. We didn't buy the truck to have problems nor do we think that we have to be the ones to fix it. When we took it to the dealer for a recall on the brakes, we told them about the overheating and they said it's normal. Add my name to your list of rather unhappy customers. Anyone here own a new Powerwstroke - how do you like it? Nils

My best friend has a 05 powerstroke, he pulled a toybox trailer up to the sierras last weekend. Said it got a little warm going up the four lane hiway, a little like 220-225.

I am about to take delivery of a 2005 2500hd and am wondering if i am doing the right thing is this overheating problem related to the earlier trucks made? Thanks for all replies

I am about to take delivery of a 2005 2500hd and am wondering if i am doing the right thing is this overheating problem related to the earlier trucks made? Thanks for all replies

get the 06. I have a good feeling about the changes they made.

2005 3500 crew cab long bed trying to pulling 16,000 pounds. This truck overheats on all grades that i climb. My first trip from SF to LA at the top of the grapevine coolant temp just out of the red and transmission temp was 250. Out side temp was mid 80's. The dealer said that it is normal and as long as it didn't get in the red it was okay.

I just got back from a trip to Trinity Lake. Every incline the gauge hit 230 and when I was really climbing a hill it would keep climbing to the red and that stupid loud fan would change pitch every couple of seconds the whole trip. I don't know what is worse the noise from the fan or the overheating.


Rob

Got the same thing, dealer says as long as it's not in the red it's runnin "perfect"

So does it never actually get to the red?? Seems you could just take a snap shot and then quickly let off to let things cool down. Hard to argue with that kind of proof.

DWIT, Pictures aren't necessary. A true overheat condition is recorded in the ECM and can be confirmed at any dealership by Tech II. Just running higher coolant temps won't register an overheat condition.

new2dmax, I to would opt for the 06. ;) JJ :)

I've been a quiet observer to the overheating issue. I too have a truck that overheats. most recently my transmission has gone into a protective mode causing me to have no power. A lawyer we know told us to file a complaint with the nhtsa. He said this is where he looks to find cases. Anyone having overheat problems should file as it could be hazardous due to fires/slow speeds due to limp mode. Just a thought

I was also instructed to file by a lawyer. This info is accessed by many parties...

Rear end every 3000miles, Please Wallbanger

Before you buy the Dodge check out the prices for keeping it maintained.... My friend has a new one and they are making him change the rear end oil every 3000 miles... 150.00 a pop.... He is going to sell his because he can not afford the maintance.... Just a warning, check it out first...

I filed a complaint in July 2004 when my previous truck that GM bought back due to overheating (http://www-odi.nhtsa.dot.gov/cars/problems/complain/results.cfm), and have not heard back from anyone at NHTSA as of now. Maybe it helps, and it certainly can't hurt, so I too encourge anyone and everyone to file a complaint.

OK folks, what's the deal on this overheating? We've made one trip to Washington state from CA over the mountains with one grade (Ashland grade) being seven miles of 6% with the A/C on pulling approx. 14,000 lbs. & no problems in either direction. We've also been in places with steeper, but not longer, grades & everything really runs well. Both engine & transmission temps were well within safe limits. Am I missing something?

Poppo3, not all LLY's are experiencing high ECT's when pulling. Just keep an eye on things on long climbs. Hopefully you won't have any issues. JJ :)

So- who has had luck in getting a buy back done, and how bad it cost you? GM has made an offer on my 05, mileage $$ plus the $$ MSRP to MSRP on my 05 to a 06, looks to be about 5k out of pocket. They are swapping the bolt on mods and paying for the non removable items, I have to swap the "electronic" stuff. Is this normal or am I getting the short stick?

plowman, seems less than what you would have to pay just to trade up anyway, and then they are swapping the bolt on mods and such. I think for $5000 out of pocket I would do it. You are getting a 1 year newer truck with 0 miles for better resale value if needed.

So how does this work?

Do they say, you paid 40k + TTL for your 05 so 44k out the door. You got 10k miles which is say 10% of the truck life, so subtract 4k from 40K and we will give you 36K twards your 44K truck. Then we will sell you a new one for the employee price of 36K and you get to pay TTL again?

So in reality you only pay TTL?

I think its MSRP to MSRP minus mileage.

MSRP to MSRP, Then usage based on MSRP divided by100,000 x mileage at first report of problem, in may case I had 5800 on the truck due to winter but we did agree that it might have been there prior so we split the mileage. I tried to trade the truck at another dealer but they checked the service history and said --Sorry not interested in trading. My gripe is there is no $$ for wasted time, and my time to switch thing off the truck. All n all not a bad deal, just all the work I put in is wasted but I get to do another truck right away and I can order anytime in the next 2 weeks,,, so I'm going for a LBZ. OH and don't forget the tax man, he gets his share also.

So do you have to buy another GM?

If you could, you could get your money from the buy back (based on MSRP) and just buy another truck at employee pricing. No?

You get a refund on the tax you paid on the last truck as it's a "return"

Nope- I owe the tax $$ on the difference is what I was told. If you Know other wise please let me know.

Not sure if I can change at this stage- the first thing they asked was if I wanted a replacement or money and when I said replacement I was sent to this department. I would guess if I changed my mind now everything I have done for the p[ast 6 weeks is worthless. I agree, probly could have saved 5k with the employee prices and rebate but not sure how the $$ would have come out.

My 2005 LLY also overheats on hills while towing. I have watched the engine temperature climb to 240 degrees on the Grapevine between Bakersfield and Los Angeles. Speed: 60 mph. Outside air temp: 90 degrees. Trailer: 5,000 pounds. Clutch fan: roaring like a jet engine. I'm sure if I kept pushing it, the engine temp would skyrocket to the redline. I'm not willing to let that happen, so I baby the truck in the slow lane to the top of the hill. This is really pathetic, since our '99 Suburban with the 454 gas engine could do the same grade with no effect to the engine temps.

I'm really disappointed with my first diesel tow vehicle! :rant:

Well Phase 2 is done- truck is ordered with a TPW of 10/10 and should be to the dealer by 11/1, paper work go's to the repurchase dpt now for the final checks etc that need to be cut on the GM side and then I get to pay the differance MSRP- MSRP plus milage and tax. The fun starts- removal of all the toys:(

plowman, did they have you sign papers saying you would not talk about this? If not I'm sure they will soon. Don't ask me how I know.:)

Hey Plowman! With a 10/10 TPW and a 11/1 Expiration of Transit your truck should have the 06 LLY. We have been told the LBZ will be released in December. Your better check it out if you are expecting an LBZ.

Have the order from the GM Workbench in my hand- LBZ- 6600 v8 HO duramax :ro)

Not yet):h but who knows. Until then- I can't complain all in all is has been a fair program, and I plan on ordering another 06 2500HD after I get this one. Unless 08's are going to be real early:rolleyes:

Won an LS 05 short bed crew cab on ebay 4574616080 and now I will not send him the check. I like to be a man of my word but I do not want to throw my money away. I want somebody to change my mind, I want the truck.

Be a man of your word! Its all you've got!!

I went through two buy back yow different mfgs and both made me sign in blood that i would not talk about it, which makes me talk about it even more.

hhmm Here is an idea for you guys who arent getting results and having dealers turn you away because there is no fix. load yourself up a trailer ( with in the published towing limits of the truck) pull er untill the engine starts over heating. then continue to pull er untill it cuts out or blows up. repeat untill the desired effect is obtained. If the new engine they put in does it , cook that one ,,, if the 3rd engine does it cook that one also. document everything , have your lawyer right a spiffy letter include this with your complain letter and the documented 3 times no fix.

If everyone of you did that 3 times that would cost GM enough where they would have to do somthing.

Well I just got another call from my CRM with GMC customer service center reguarding my File. It was not a pleasent call to say the least. Their position is my truck is 100% normal. They are closing the file, with a note saying dissatisfied customer:mad: . They are also sending me a form to send to the better business Beauro (sp).

On of the things that really upset me during the call was when Megan (CRM) explained that their were to versions of the Duramax, the more powerfull LB7 and the newer LLY which had less power and was able to do less work. I asked her if she would mail me that information in writting. She said she could not and would not. Talked to her boss, he also stated the LB7 in the 01-early 04 was stronger and more powerful and the 04.5 to 05 were detuned and can not be worked as hard as an LB7. :eek: So again I asked him to send it to me in writting. He replied he could not. He did say my local service manage would give it to me in writting. I will be going to find this out ASAP. I have a very strong case if they will give it to me in writting. AS we all no the LLY is rated for more HP, More Torque and LLY trucks have a Higher GCWR.

What are my options now that GMC refuse to fix my truck, and now that they state my file is closed as dissatisfied?
