The thermostat may not be opening properly, preventing hot water from circulating to and cooling in the radiator. The water pump may be failing and can't circulate enough hot water through the radiator. If the head gasket on the engine has failed, combustion gases from ...The t-stat only controls flow to the radiator. Since the coolant pump is not pumping coolant, there is no coolant flow to the radiator, or the heater, therefore the heater is cold, and the engine overheats. If the t-stat was stuck closed the engine would overheat, but there would be plenty of heat from the heater.Air gets into the system to replace the coolant volume that spilled out when you changed the t-stat, and the air blocks the flow of coolant through the system. That results in the heater core not having any heat and preventing getting the hot coolant from getting from the engine block to the radiator where it could get cooled properly. No vent ...There are several reasons that your car may overheat: Low coolant level: If you haven’t checked the level in the overflow tank for a long time, it may not contain enough coolant to keep your engine at an optimal temperature.
