Product overview
A thermostat housing assembly for Toyota and Lexus models with the 3.5L V6. It controls coolant flow between the engine and the radiator so the engine warms up fast and stays at the right temperature. Coolant leaks at the housing, overheating, a temperature gauge that stays low, or poor cabin heat are common signs of a failing thermostat or housing.
