Thanks. I thought that this might be the problem, so I cracked open the upper radiator air bleed and coolant came out, so I closed it. Then I did the same thing with the temperature sensor that is on the intake manifold and coolant also came out. I don't know if this is positive proof that all the air is gone, but it is what I did. As far as bleed holes in the thermostat, I do not know if there are any there. But my car is number 290 and I have had it for 21 years without this kind of problem, and it has the same thermostat in it as when it was new. Is it possible that I still have air in the system? If so, how can I get it ll out?
