2003 chevy duramax

have the opportunity to purchase a 2003 2500 chevy duramax with allison 5 speed . the truck has 141,000 miles . the gas 6.0 2003 2500 i have now has 140,000 miles . the truck looks and runs great . the owner has taken very good care of it and has added the heavy duty transfer case and built up rear end . it has an extra external fuel tank that fills the regular tank as needed . it has the banks system the owner says he never goes past setting #2 has had new injectors installed , exhaust brake , all the extras, air bag with the remote compressor . it's the extended cab with a 6.5 bed . the only thing i don't seem to like is the shorter bed and the color . other then that is seems in great shape . the owner is in his late 70's and has been hauling a 5th wheel which he is giving up because his wife is having issues and he's looking at a MH . the price is right around 10,000 or just a tad less . i feel i can get 8500 for my truck and think it may be a good time to make the jump the diesel . new tires , etc

so anyone with experience with the older duramax's any suggestions

Hi,

Those early Dmax years (the LB7 engine) had injector issues that could result in exceptionally costly replacement procedures. Some didn't even make it to 100k miles, and Chevy had to extend the warranty because the issues were so extensive.

I suggest you get the service records for that truck and also find out what new injectors might cost you, since it's long past the warranty period. But if they were replaced recently, then that price range sounds pretty good.

FWIW.

yes new injectors replaced under recall / warranty . apparently they are some sort of upgraded injectors . i don't know diesels . also seems chevy extended the warranty of the diesel injectors to 200,000 miles for these yrs 2001 to 2003 .talkingwith the gentlemen seems he'll let me have it for around 9000 . witha 6.0 gas with 140xxx and trade to a duramax 6.6 with same mileage . i know it hasa big after market trans cooler with it's own fan . he did seem very knowledgeable on the truck and what he had put in it . it's a one owner truck . just don't want to get into something i'll regret .
one 5000 dollar repair bill will make it a disaster after all i can replace the 6.0 engine and tranny for just about the same price

I think a 2003 would get better fuel mileage than my 12 Silverado. I just like a diesel but that's my opinion. I put about 20,000 miles on my diesel each year

I agree. The early Duramax's were prone to injector problems. Replacement injectors from a local parts house will run $260 - 350 each depending on brand and if remanufactured or new. The Alison is good but if you could find/afford a 2006 or newer, the Alison in those will be a 6 speed. The "one owner" & elderly deal is really good.....us old guys don't like problems and tend to really keep after things. Good luck with your decision.

Hi,

Spock is right. My 2001 LB7 got about 2 mpg better than my 2009 LMM engine, and the favorable economy of that engine is pretty well known. Less emission equipment seems to be the reason.

The LB7 had the fuel lines running through the valve covers, and that combined with some other design elements that made injectors fail early, and replacement complicated and expensive.

FWIW.

Hi,

Bear in mind that the warranty was 200,000 miles or seven years, whichever came first. So it really doesnt help you going forward.

My second set went out at 175,000, luckily just before the seven years elapsed.

You may want to do some searching on thedieselpage.com as a further resource.
FWIW.

It's not an easy one . My truck i know well, this one i do not . But seems just the upgrade to diesel may be worth it , the low mileage on it, I'll find out exactly how long ago the injectors were changed .
Any newer ones I've looked at where 2 to 3 times as much and almost twice the mileage .This deal may only cost me a couple grand . the guy really new his truck & what was done to it . you could see the pride of ownership .
I look at my truck and feel guilty looking for another

Hi,

His mpg claims are close to what I experienced. Depends on speeds, height of trailer, etc.

With my 2001 LB7, I got as much as 21 unloaded with a topper, and 18-19 typically on the road with a bare bed. I got between 10 and 11 towing a 32 foot Jayco fiver.

FWIW.
