well,i just purchased an 05 chevy 2500hd with the diesel.8th vin is a 2 so its an LLY.i started doing some research and found this page and now i am worried that i just bought a overheating POS
.i am having some problems with most of your abbreviations in the posts so its kind of hard to follow some of your explanations.from what i understand is that gm can/may attempt to fix my OH problem with an airbox set-up from an 06 model and a reflash of the computer that will cost me power and mpg.but i also read that i can fix it for about a grand myself...what would i need and will i still lose power/mpg's?i have a toy hauler that max's at 12400 gvw so i am rightfully concerned.can anyone steer me in a direction or two?
