i'm looking at a 2002 chevy 2500hd 6.6L duramax diesel...it has 103,xxx miles...and I had it mechanically looked at and everything passed...but the service engine soon light is on...should I be really concerned?

You need to get a code reader and see what the code is for. Probably minor if it runs fine( glow plug,glow plug controller, ect.).

check the code, and check to see if the coolant is low, also check the transfer case to see if the famous "pump rub" has occured.

whats pump rub?

whats pump rub?

It is the pump in the transfer case that breaks and starts to rub on the case whitch wears a hole in the case. Usually happens at the top , back-half section of the T-case. The make a repair for it. I have 104,000 on mine with no pump rub issues......yet.

should I put it in 4hi and 4lo to check for that?

Definitly! If it shifts smooth your good. But I would see if you can read that code some how. Test drive it to an auto parts store. Most have code readers you can use.

ok cool thanks for all the help! I can't wait to pick it up :P

transmission limp...................

transmission limp...................

Then it would be stuck in a gear and won't go over 45mph.

"Then it would be stuck in a gear and won't go over 45mph." .....yea i test drove it shifted very nicely...almost had it floored accelerating to 0-120km/h

Sounds good,but I would still check on that code just to be sure.

oh yea I forgot to mention the guy told me the engine service light was on, but when I test drove it, it was off....then he told me when he took it the inspection it was off...then the people who did the inspection said it was on?

Is this truck at a dealer? If so have them scan it to see if there are any codes. Usually the SES light will go out at 5 cycles of the ignition.

no its at a used truck dealer...and he tells me that he doesn't want to spend anymore money on it...(he got an oil change done to it because the inspection recommended it/filled the gas tank/ and got the inspection done on his cost).... the inspection papers say it also needs a serpentine belt which i can do, and tranny cooler line is leaking which i can do...but i haven't asked him to get it scanned so maybe I should call him tomorrow and ask.

Yeah I would get that checked out before you buy.

what could be worst case scenario? ...yea i'm gonna call and ask tomorrow

As for the pump rub, Get under the truck and look for the hole!!!!!!!!!!!!!!

Just because it shifts smoothly, does not mean anything, mine shifted smoothly without any oil in it!

You have to get under the truck and look for a hole! If it is there, Good news, it is an easy fix, and you can tell the dealer to take 1500 bucks off the tag so you can fix it, then JB Weld the hole and fill with fluid and install a good fix like M/A's later!

I have never heard of this pump rub before. I am going out to my truck and see tomorrow.

Worst case scenario, is you dont check the code, the trans or motor is about to let loose and you have to pay $5000+ to fix it.

Yeah man, you need to make sure. I spent a hundred to have mine checked out thoroughly by a tech. All he found was a leaky seal and the kid who I bought it from got it fixed on the spot. It's worth it.

hey guys, well I called the dealer and he told me that the serivce light wasn't on, he got it mixed between another truck :confuzeld...but i got the truck home now and I love it...here r some pics...:ro)

Very nice!!! Congratulations on your new baby!!! White's good.

interesting rims for an 01

What rims did the 01's have?

its an 2002, and I don't think i've ever seen any other rims than those aluminum factory ones before. I thought all duramax trucks in this body style have those ones.

Well, some have all steel wheels, and not the factory alcoa's. But i thought that an 01 would have them. Those look like the right rims on your truck. That's what all the 2500HD's have.

oh ic, hey do you know how I can find out if my truck has a open, limited slip or g80 diff?

I think someone does vin checks. But you have to ask nicely.

Looks very clean.

Look on the inside of the glove box door. If it has a g80 rear end, it will be listed there.

looks good!

i want to change my fuel filter soon...have read up on the procedure on here..but can't u just remove the filter fill it with fuel and put it back on?

Well, you need to put a new one in there. You can't just empty and put the old one in...
I hope that's not what you were asking. If it's not, then yes, I unscrew the old one, put the new gaskets in, screw in the sensor and fill with fuel, screw back in. A little priming and you're all set.

yea sorry should have re-read my post there...but yea thats what i mean...new filter/gaskets/screw in sensor and screw it back on...to prime it you just have to loosen that screw until fuel comes out...with the truck now running?

i have had to prime it a few times with alot of fuel coming out to get the truck to start.

might want to look at stainless steel bleeder screw

yea a lot of people have been telling me that, where can i get one of those?

check ebay, its like $10 bucks, sure beats the crappy plastic one

i have had to prime it a few times with alot of fuel coming out to get the truck to start.

My driveway has a little hill and my truck has to be facing downhill to get primed after changing the fuel filter.

oh thats interesting...my driveway has a slight slope too ..when i do my filter this weekend i'll face my truck downhill
