the service manager said he had talked to some big wig in Detroit who thinks he knows whats going on with the overheating. they have had my truck all week and said they need to drive it while doing some tests. i don't understand what they think this will accomplish being as they are not pulling anything. are they testing for a program or if its chipped or something to blame it on? even with tech 2 in place what do you think they are looking for. i did take a mechanic for a ride last summer pulling a tractor with tech 2 and it verified it was overheating. what do you guys think?

I really doubt they have a fix. They would not be buying the trucks back if they had a fix.

There will never be a fix from GM because for there to be a fix they would have to admit the problem and that would mean recalling ALL Dmax engines in both light duty and medium duties with the LLY produced 04.5 and 05 up to the 06 LLY start date. No way is that going to happen, it costs too much.

We have already heard from insiders high in GM that this one is going to be swept under the rug, so everyone don't waste your time hoping they are going to make it right for you.

PROVE ME WRONG GM

The truth often hurts but sometimes its best......

Because they have to at least go through the motions, they can't refuse a legitimate customer complaint. Also, it seems some district service types have been taking shots at cures with the Ron Davis rads and such. Would be nice if they would pay for what I have coming....that would be fair.....

In order to qualify for your states Lemon Law protection there are mileage/months of service guidelines that must be met. In Indiana it is 18 months or 18,000 miles ... so basically you have to report the problem within this amount of time/mileage.

At 33,000 miles my guess is if you experienced overheating and GM was unable to fix it you would have to get a lawyer and sue for breach of warranty.

I have 34,000 miles and and just bought the truck from a private party ( He got me :mad: ), so I am sure that I have no legal recourse. If GM is listening - this is exactly why you are are in the financial trouble you are in. If a fix does not come available, I will be putting the truck up for sale - any takers?

I will either go to a 2500HD 8.1 or a Ford PSD.

I will wait a little longer.

I wouldnt jump ship just yet .... there are a few guys on this site that are pretty sharp and if they say they will have a fix Id give them some time to produce.

Im not sure of overall cost of a "real" fix but it would almost have to be cheaper than trading trucks.

I know this doesnt give much satisfaction when it comes to GM but it will save you money in the end.

I had a over heating problem too, but after I did some mods it went away.

I installed the EDGE chip with Attitude and then the truck would not accelerate and had white smoke coming from the tail pipe.

I checked into the problem and was told that I should have the computer reflashed - so I did.

I pulled the chip out and went to the dealership, told them about the smoke from my tail pipe and they said that there was a reflash for this issue.

I can now pull the same weight and I have no overheating problems.

Some of my other modifications are:
  • Exhaust/deleat cat
  • AFE stageII intake
The truck has 33,000 miles now and it runs perfect:)

I have a 05 cc/4x4 Dmax with all the add-on stuff to help the cooling, still a problem. Pulling a 28k Desert Fox in 65 degree heat up 6%, the tranny spikes to 260 and engine 250. I had it in to the dealer twice in the past month, no change. Funny thing is, I have the same truck in an 8.1 that I could not sell due to the high fuel prices. Now I'm glad I still have it, power is about the same pulling the hills, especially when the fan is screaming on the DMAX! No problems with heating what-so-ever! Last camping trip I averaged 5.8 MPG with the DMAX! 6.2 with my 8.1 with the same load. GOOD GREIF!:cool:

I hope you are as confident when summer rolls back around for real.

That reflash that "cured" you.....it cured something alright, it cured your temp gauge from telling you the truth and moved your alarms into orbit to keep the asleep.......

I know you don't want to hear it, but if you overheated before, and did the things you are saying you did, then you haven't helped yourself at all. You'll find out this summer....

In Texas you have 24 months or 24,000 miles. After that you no longer have the law on your side and it gets very expensive to sue. :(

I am sure you guys know the outcome of the test. was told the service manager drove it today and could not get it to act up. they drove it around empty with a temperature of 40. i have been so upset and mad about this whole overheating thing that now all i can do is sit back and laugh. i haven't thrown in the towel yet. i have great faith that the guys on here will get it fixed. i only hope it's before summer.

Dude - I don't know what's driving the negative thoughts, but I did tow after the reflash.

The overheating problems I had were in the summer of 2004. I did the modifications and reflash over the winter of 2004.

I towed 23,000 lbs over the 2005 summer - over Wolfcreek Pass in Coloraod - 4 times - no problem.

Then towed through CA Mohave desert this summer - 106+ temps - still no problems.

I'm not worried.:cool2:
