Diesel Chevy truck with new Duramax engine
We found a 2004 Chevrolet Silverado and other C/K3500 4x4 Crew Cab that has a brand new Duramax 6.6 or 6.5 engine in it. Dealer was not sure...we will have to go look at it. How are these engines?...

The LLY overheat issue was due to an undersized turbo mouth piece. There was a GM issued TSB about it. Upgrade it to an LBZ mouth piece & the problem is solved. I did it soon after I got mine (89K mi.) and has never gotten close to overheating.
