I’m working on a Chevy 2500HD with the 6.6 and this is my first diesel. I have experience in this kind of stuff, just not diesels. And I want to make sure I dont acciedentally miss anything
I’m replacing the old head gaskets with some new ones, but the problem is that I’m coming into this job behind someone so I didn’t get to tear it down and get familiar with the engine.
What are the torque specifications for these engines? And is there anything else that I should be aware of?
