Ok had a Chevy mechanic at the house, my neighbor, and ran the truck: checked coolant levels, got tstats to open, and bled the system... Trying to work out any air bubbles. We had the system overfilled and had NO air bubbles in the tank while running
He is not a diesel mechanic, but knows his stuff. He is coming by in the morning to check radiator hose "hardness"
Anything else we should look at why I have him over, he is going to run all of the info by the diesel guy at Chevy tomorrow.
Let me know, I am still hanging on by a thread that it is not a HG... Please someone tell me something... (good) haha
Thanks for the help so far
