I wonder if the cooling ability (heat rejection) of the previous Duramax was the limiting factor? GM seems to have done a number of improvements in that area with this newest generation Duramax, and they have to be sensitive to the issue since they screwed up the engineering of the 2004.5 and 2005 LLY overheaters....
ib516 You must have nightmares about the early duramax's so let it go and enjoy the new trucks. If our 05 was an overheater it would not be towing our alpenlite. If it was a truck with years of poor front end suspensions it would not be doing it either.
102000 miles and runs awesome.

No nightmares here, though I did drive one my dad owned and I towed his 26' TT with it. Any little hill and the cooling fan was screaming. I have no doubt on a steep grade with a heavier load it would have had the temp gauge climbing to the red zone.
Speaking of which, why do you have the aftermarket oil cooler in your signature on your truck? What is it, the TD-EOC ...that was marketed as a cure for the LLY overheating woes?
Come on Larry - There's only about 1000 threads on the Duramax forums about those trucks overheating :B
I will say the new trucks look pretty awesome and with the exception of the early injector issues (2001 to 2004), then the overheaters of 04 and 05, the Duramax has proven itself as a great powerplant.
