O/T Duramax Diesel engine hours

Todd D · Apr 7, 2011

Looking at a 2003 Duramax. How many engine hours do you guys think these engines will last for? The one I'm looking at has 6000hrs. I know there is lots of factors to this question but I was just wondering..
Thanks Todd

The Duramax is made by IZUSU. Life depends on
how often you change the rice!

Maintenance?
Uses?
Condition of truck?
Milage?
LOTS and LOTS of variables here.

Actually, it's made in Moraine (Dayton), OH by DMAX Ltd, a joint venture between GM and ISUZU.

Lot of injector issues!

The 2004 and older duramax's are the better engines and have better fuel mileage

Todd,
A rule of thumb used is 40mph ave. Ifyou have 6000 hrs that would be roughly 240K miles.

I didn't answer your question, because as you said there are a lot of other factors. Mileage, maint. did it spend a lot of time idling. From what I have seen, the truck wears out way before the engine if properly maintained. I believe the 2003s were out of the injector problem. You can google to be sure.

I put a bid on a truck the other day it had 345,000 miles, 2004 D/max. It sold for 12,000. I was shocked, way more than I would have paid.

I have a 05 with 233,000 miles and roughly 4,600 hrs. I had to replace the fuel press reg at 230k, and front wheel bearings at 170,000k. It could use brakes but I want to try and get 250k out of them just to see if I can. I wouldn't let the hrs scare me I have seen 10k hr equipment in way better shape than 3k hr equipment, just depends if the owner gave a flip or not

Thanks for the help guys, I trust tractor guys. It has 268,000 kms so it looks like it has not spent most of its life ideling like alot of Oil Rig trucks I have seen. Will go check it out on Saturday and report back if I have any more questions. Did do a Google search and reviews/Good & Bad in 2003 came back fairly highly rated.

Ive got an 03 G.M.C. with the duramax . I absolutly love it . The injectors are a known problem but if they havent gone bad with those miles on it they probably wont . Not saying they wont wear out . Everything does . I love my truck though . Wheel bearings and tie rods are also known problems . Timken makes a replacemant thats gauranteed for life though .

The injectors are under warranty up to 200000 miles.

I've seen 40 quoted , the Cummins B engine service manual lists mile / hous service intervals that work out to 35 MPH.

By the time the above truck gets resold, I bet it shows 145,000 miles.

I have a 07 with 3000 hours, just getting broke in. I am trading it in next week, not because of the hours, I am just tired of it.
