I would go get a block test kit from your local NAPA or auto parts store... Many guys poo poo these test kits, but it diagnosed mine in a matter of seconds. Not good, I nursed mine for a year, and then she was building so much pressure it blew out my radiator and my lines running to the Tri-Pac... The Tri-Pac episode was the end... She went in for the in frame a few weeks later. I think you are looking at a big bill here... If you have high miles, sounds like in frame time. If not, you may get away with a head replacement or just a new head gasket. If it is the head, just get a new OEM one, do not get a reman. I think you had a high heat episode, if you have an inline 5 reader and Insite, it will show up. If not, take it somewhere and pull up the ECM recordings to see. Sadly you need to be a mechanical engineer with these new trucks, as these shops are clueless. The truck only has 200000 on it and the pyro never goes above 950 | |||
