I have recently almost done a complete overhaul on the engine. New heads, Water pump, radiator, fan clutch and new thermostat. We purged the radiator
through bleeder valve till no more air comes out. Car
wants to still run hot when turning on the ac. We took off front and looked at water pump impeller to insure it did not come loose. It was ok. Again car will run for a short time before it tends to start going over to hot especially when ac is on. I am at my wits end and out of money. Can some one please help here and can think of what we are overlooking.
