I am might do a compression check on it tomorrow. But that won't confirm its not the head gasket, depends on where the gasket goes at. I starting to think its either the coolant gauge temp sensor or the temp guage itself. Check this out. I changed the sensor that turns the fans on at certain temp and the fans do not go on, so maybe the car is not getting hot enuff, maybe the guage is wrong. I'm going to get a cheap temp guage tomorrow and hook it up into the spot for the temp sensor and see how hot it gets. First I have to put the radiator back in. I pulled in and ran the hose thru it. Its not clogged at all, it flows just fine
