tks

In an emergency you can turn the heater on wide open. Had to do that in a tunnel one time with stalled traffic.

Time to pull the radiator for service. Overheating can damage a thermostat in extreme cases.

Did you clean between the rad and AC condenser? did your overheat condition happen slowly over long distance( temp gauge slowly climb up)?? if so I'd bet on plugged rad internally or externally

Did you have the AC on?
