View Full Version : 2500 duramax lifespan ???
03-01-2007, 04:40 PM
I know this is a broad question but approx. How many miles can I expect to get out of a 2500 Duramax. I am looking at a 04 silverado crew cab with
75k miles and they are asking 28500 . Sounds like alot for that many miles but if I can get 350k out of it it might be worth it. This will be my first diesel that is why I really don't know what to expect as far as milage. Any thoughts?
thanks in advance

eternal - I hope!
The 2007 comes with a 100,000 mile engine and power train warranty if that tells you anything.

All the GM products are coming with the 100k warranty. Go to www.thedieselstop.com or www.thedieselplace.com and ask the same question.One of those is the ford site the other is the gm

I dont think the duramax will go that far, especially an 04....as far as the price i think thats too high. I dont think ive seen a duramax with more than 175k. All the diesels out of the big three come with 100,000 mile warrantys. thats a given.
The LLY (04-05 model years) motor is not as good as the LB7 or the LBZ in my opinion. That is not to say they are not durable.

yep! that LBZ is damn impressive. havent towed with one though...

Ive heard that some Duramax engines (I dont remember which ones) were really only a 150,000 mile engine. I am a Ford guy myself but I dont want to get that started. The Ford 7.3 is an engine that refuses to die.

i was hearing they go about 150-200k before they need rebuildin. so i dont know.

The Ford 7.3 will run for 4 or 500,000 usually before you even have to think about rebuilding. I have a friend who has 7.3 and a 4-speed auto in a '96 E350. Its nearing the 400,000 mark and is still running strong with only a couple of minor problems. That big ol cargo van body is going to rust right off that truck long before the engine up and dies.
Here is a thread going on the Diesel Page.com
200K miles or less before a rebuild would not cut it. The length between rebuilds varies. I have seen 7.3's that never made 100K and others that have gone 2-300 K. The Duramax is every bit a long life motor as anything else on the market. Izuzu builds a great motor. There commerical diesels are very durable and are run in many off road applications. CASE, Deere, Hitachi, Link Belt all use Izuzu diesel engines in their excavators. I think the Duramax will prove that it will be a long life motor. It has not been out that long in respect to the 7.3 and 5.9

Some guys have 200-300k and still take on long distances hauls, 78k for a diesel is just breaking it in too. Bu 28k for a 04 is a little steep.

There was a guy on Diesel page with an LLY that he used for hauling cars. Had 425k on it without issue. That made me feel better about mine.

I have purchased my Duramax after looking around for a while and researching. If you go on EBAY, alot of the Duramaxs' have well over 200000 miles and they are asking a ton for them. My point is these trucks are like everything else. If you maintain it right, they will last for a long time.

Do you think its better to buy new because you don't know how well the last owner treated his truck? I mean is it worth the extra money for a new?
Also its obvious that 28k is high for an 04 with 75k miles. What do you think would be a reasonable price for an 05-06 2500 with that many miles?
There are some major differences between an 05 and an 06. The 04-05 are the LLY motor and generally considered not as desirable as the LB7 and LBZ. So to compare an 05 Vs an 06 is not a good comparison. I think the LBZ is the best rendition of a Duramax yet. Although my mileage is not what my LB7's would do. I have more power and a 6 speed tranny with more improvements. I would not be overly concerned about buying a used Duramax as long as you still have engine warranty. When buying used you can have a dealer run the VIN and get a history of the work that has been done to it. It will give you an idea of what kind issues if any it may have had. I would try and find an 06 if you can. My next choice would be a low mileage 03. The 03 models have the updated interior with the LB7 engine. Last would be a 04-05 model. There are many performance mods available now for the LLY which will help these engines. Check out any of the Duramax forums and you can learn tons of info. I like the Dieselpage.com

With the new Chevrolet body styles coming out, you are likley to find very good deals on the old body styles. In my opinion, if you are in no immediate hurry, I would wait until after truck season - Winter - and until Chevrolet starts to move the New Body Styles onto the lots. Then you will see your share of very good used trucks with decent mileage and also they will be trying to clear out the "new" old body styles with rebates and special financing. Pateince when buying an auto helps big time!!
