Brian nailed it on the head!
Blew my headgaskets last year. I replaced the gaskets and bled the cooling system. Took it out once last year after I did them and saw that it was running hotter than normal after the run and took awhile for it to cool down. I thought maybe it was the thermostat. I drained it and put anti-freeze in it over the winter. This year i replaced the thermostat, and bled the cooling system again with a spill proof funnel. I figured I was good to go.... Went to the Valley Memorial day weekend and same thing happened. Running hot after the run and took a while for it to cool down.... ![]() Brian comes over ask me whats wrong, leans over and looks at my radiator. There's your problem, there's no air going through the radiator! When I blew the gaskets, it pressurized the cooling system and blew up the rows in the radiator crushing all the fins together. ![]() ![]() ![]() Just wanted to post this up in case some one has the same problem after blowing a headgasket. I never even thought to check it! Thanks Brian!
