...Then running well below normal while driving. Upgraded my radiator a while ago, burped it numerous times to get the right amount, and just when I think everything is back to normal, I'll overheat, pull over, and now my coolant overflow is WAY above full.
This has led me to believe that my thermostat has gone **** up. If I'm wrong, please feel free to enlighten me. My next step will not be to replace it, just to remove it for good. I live in Florida so it's hot most of the time, and hotter than balls this time of the year.
Ok, let me have it...
It could be the thermostat. To know, buy a new one, pull the old one and boil the two of them together in a pan on your stove. If the new one opens first, it is the thermostat,
If no difference, check that your radiator fans are running.
If they are then you probably have a blown head gasket.
Running without a thermostat is a bad idea.Any way if it was the thermostat it would be overheating no matter what.I agree with the other guys,check the main fan.Start the car and let it idle to warm up.If it overheats before the fan kicks on then check the fan fuse and go from there.
+4 on the fan, not the thermostat. Just see whether it's turning when your car is sitting still.
