I just got here, so hi to everyone,, I guess what brought me here is that I have an overheating LLY and I have had it for a while 46,000mi. I had not experienced any real overheating until I was in the MT's the last couple of week, and I was really done away with. I thought I had and indestructable Chevy Duramax., HA..ha.. I don't think there is anything I can do so far as GM is concerned, they act real no chaulaunt, like they never knew of such a thing? Maybe I just want to know what the best thing to do is? Is there a real fix or do I just have to keep an eye out for places to stop and cool off?
