Description
This premium-quality complete coolant thermostat housing assembly is manufactured to exact original equipment specifications to restore precise engine operating temperature control and reliable cooling performance. Integrated with a durable composite housing, precision thermostat element, high-grade elastomeric sealing gasket, and a temperature sensor/element connection, this unit opens and closes reliably to regulate coolant flow to the radiator. Replacing a cracked housing, stuck thermostat, or leaking seal prevents engine overheating, poor cabin heater performance, excessive fuel consumption, and related diagnostic error codes (DTCs).
