The thermostat housing on your Volvo S80 T6 and XC90 is an aluminum housing complete with thermostat and temperature sensor. The thermostat maintains optimal engine operating temperature to improve fuel economy and reduce engine emissions. When closed, coolant circulates through the engine, allowing the engine to warm up. Once the engine is warm and engine temperature reaches a certain point, the thermostat opens for coolant to flow to the radiator where it is cooled before returning to the engine. Once the engine has cooled enough, the thermostat closes until the engine temperature rises enough for the thermostat to open again, regulating engine temperature. This genuine Volvo thermostat housing with thermostat and sensor is the original thermostat housing used on the 2002-2005 S80 T6 and 203-2005 XC90 and is the recommended replacement thermostat housing for your Volvo if yours has failed.
