Product Overview
This thermostat controls coolant flow as the engine warms up and begins working. A thermostat stuck open can keep the engine too cool, while one stuck closed can cause rapid overheating.
This listing is for the 76.5°C specification. Match the part number, diameter and temperature marking to the thermostat you are replacing.
If the engine still runs hot after thermostat service, check the water pump, radiator, fan and coolant flow before assuming the new thermostat is at fault.
