thermostat or air bubble?
Yet the latest in my wonderful series of problems. I tried "burping" the cooling system like was suggest and still no luck. I have added more water to that thing than a fish drinks in a year. (about 5 jugs of 50/50 i think) I know she is not leaking and the headgaskets are good (just replaced them and the oil is not milky). When ever I try and drive it she slowly warms up to about the "n" in the norm then if i continue to drive her the temp jumps up to near the red. I have been trying to get the air out by driving it around and getting it warm, shutting it off, taking the vent plug out to releave the pressure and topping of the radiator. The upper hose gets very hot and feels like it has just air in it and no coolant. Could it be a stuck thermostat, or should i just keep doing what I am doing cause there is an air bubble somewhere?
