I noticed the temp gauge was all the way up on hot. I went to turn the heat on to cool the engine and cold aire blew out.

better have it checked for a blown head gasket. you may have overheated it and damaged the motor.
then you need to find out why it overheated either from a leak or a bad thermostat.

Thanks, I did not see any fluids leaking or white smoke from exhaust. Are there any home tests for a blown head gasket?
Hi Roy,

I had it towed to the shop, and the water pump was seized, but I was told the engine checked out OK. So the pump, theremostat and hoses were replaced. After drving around for 30 min or so the fans came on, but ran OK. I thought mabe the sensor is shot from all the heat the night before. After I got on the highway and hit 70 she started to overheat, backdown below 70 ran cool, but the fans never went off. I went back to the shop and now the fluid goes from blue to yellow. I have been driving the car around town and highway for a week now. The fans come on and she gets hot at highway speeds, but no condensation out the exhaust, the oil is clean and coolant is not dropping. Any ideas. Thanks for your time. Stu
