Ok, I am paranoid. The only other car I ever had a head gasket fail was a 84 Corolla. Now my 90 is running above the middle. I have changed the thermostat with a Toyota stock thermostat, coolant and radiator cap. I am still running at the middle or a little above. My fan comes on right at 199F which is what it is supposed to do. Is this normal? Should I worry about this? All the cars I have had in the past, the gauge runs right at the middle. Also, never had a car run the fan so much. There is no sign of a blown head gasket that I can tell. So am I just being paranoid?
