Is the Duramax engine covered automatically by a 100,000 warranty? Or is that something extra you pay for when you initially buy the truck from a dealer.


I'm thinking about buying a 2004 Duramax from a dealer in Texas (I'm in So Cal), it only has 22K miles on it. The dealer offers several "extended" warranties like any other dealer. The main issue I'm concerned about would be the engine.... injectors, flywheel, etc....all the stuff I read about on here. I need to know if I'm covered because I don't want to spend 2K for a warranty....

Thanks....

Yes the Dmax has a 100k mile warranty.

6.6L DURAMAX® Diesel Engine Components (http://service.gm.com/servlets/BlobShtml?ShtmlFile=1206250&pubid=539&evc=sm&cellId=72605#ss4-1206250)

For trucks equipped with a 6.6L DURAMAX® Diesel Engine, the complete engine assembly, including turbocharger components, is covered for defects in material or workmanship for 3 years or 36,000 miles, whichever comes first. No deductible applies during this coverage period. The engine parts listed next continue to be covered, subject to a $100.00 deductible, for 5 years or 100,000 miles, whichever comes first.

So if the turbo takes a dive after 3/36, you're screwed?

For the most part anything that has to do with the engine directly is covered till 100k. Yes the turbo is included in the 100k

And some of us lucky ones get the 200K mil warranty deal......:rockit:

I thought the 200K was only on the injecters.

according to my letter from GM, injectors only is correct

Yes the turbo is included in the 100k

Really? unhooking the actuator isnt warranty? lol

I'm glad to have guys like you around Cobra since I've got a small coolant leak and since gaskets are covered I'm hoping that's what it is.

I've had a small coolant drop for a while now, I tightened up a clamp near the bottom of the pump but after just changing the oil the drips are back again. Anyhow I'm just over 38k and heading to FL in two days for a week so when i get back I'll be in the low 40's, but it looks like i may yet still be covered.

according to my letter from GM, injectors only is correct

Jim

MMMMM :eek: MM That's funny, they replaces a bunch more than my injectors and I do believe the pump is now included if it fails the tests.....

:confused:

That is for those of us that have one of those "old" LB7's :ro)

Is the Allison tranny covered too under this 100K warranty.

Allison is 36k

I just bought a GM Major gaurd extended warranty for my 02 duramax which has 24,000 on it. It cost me 1525.00 for an additional 4 years and 48,000 miles. For some drivers if you spann that cost over the 4 years it is cheap insurance. How much is a Allison repair ???Plus for a $50.00 transfer fee this can be put in the next owners name if you deciede to resell. Some thing to think about.

And some of us lucky ones get the 200K mil warranty deal......:rockit:
What 200kmi warranty deal??

What 200kmi warranty deal??
01 and 02 owners received letters that extended out the warranty to 7yr/200,000 miles on the injectors, since it seems the first two years were the most problematic. However, my 03 and some 04's have had issues, I've had mine replaced at 25,000(now at 44,000 and still going). I don't know if my warranty will get extended or not or if it's a case by case decision for the 03's and up.
