No one running this engine??????
This is a discussion on Need pros, cons on 6.6 D-max within the Duramax Forum forums, part of the General Discussion category; I am new to the diesel truck world. Looking at purchasing a '03 Silverado 3500 with a 6.6 Duramax diesel ...
I am new to the diesel truck world. Looking at purchasing a '03 Silverado 3500 with a 6.6 Duramax diesel and a Allison 5 spd trans (it's a 2wd crew cab dually)
to pull my 26' enclosed race car trailer.... what can you diesel gurus tell me about this power train? Good, bad, or indifferent?
Thanks in advance..

There's plenty of people running a Dmax.
For the most part, I've seen nothing but good reviews. Each engine has it's own set of issues though.
For the 03 you're looking at, the weak point was the injectors. I've heard that if they haven't been replaced, you really need to look into doing that.
For the most part though, I think you'll be happy with the Dmax for your needs. Like all diesels, they will pull like there's no tomorrow.

Now there's more money for the truck!
Great motor and great tranny, in stock form. If you plan on adding more than 100hp, look into upgrading the tranny. As said before, if the injectors havn't been changed out it will need them. The early duramax motors wern't designed to run on the low sulfer fuel that is now at all the stations, and this takes its toll on the injectors. Anymore it is getting hard to find '03 duramax motors that havn't had the injectors done, unless the truck has very low miles.

Power wise you couldn't be happier and they will last a very long time. However, a con in my opinion is how much it cost to replace factory parts. Like a water pump. A water pump alone for these trucks are about $600. Add labor into you are looking at $1400 just to replace a water pump. If you have to replace the whole engine...that's almost 5-digit territory without a warranty.

My father has a 2004.5 Chevy duramax equipt with the Allison trans. and this is a 4door long bed dually. We tow our 24' racecar trailer like nothing, most of the time dont use tow haul mode. Ours has 66K miles and havent had a problem yet. For fuel mileage, were are getting about 17 around town, and 18 or so on the highway, and ofcoarse with our enclosed trailer, it brings the fuel mileage down 2 or so MPG. Power wise it has towed everything we tow with it, whether it be a old buldozer we had or our racecars. I use this to plow the driveway in the winter and it does it no problem and the glow plugs takes 2 secs at the most to warm up to temp even when it is 10degrees out.
Hope this helps
You can get a engine cheaper then that and water pumps hardly fail.

My uncle's dmax 2001 has 650k kms and he hasnt replaced a thing. the truck is falling apart not the powertrain... lol. and my other part of the family all owns dmax's from 06-09 beautiful trucks and hell of a motor. if u want power and quiteness.. duramax
...even if a full crate motor would run a guy 9900 dollars...that is still far cheaper than a brand new truck. Chances of the motor/tranny going before the truck does is slim and next to nothing in my opinion.that's almost 5-digit territory without a warranty
Maintenance is key and doing it all the time should be a labour of love...it is for me..!!
