Oil Cooler Thermostat Expansion Tank with Seal for BMW

The thermostat is a valve that goes between the engine and the radiator. It's purpose is to keep the engine at the proper operating temperature. When the engine gets too hot, the thermostat opens up and lets the engine coolant flow through the radiator, where it cools off. When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.
Coolant thermostat housing assembly regulates the flow of the coolant going through the radiator to keep the engine in its stable operating temperature preventing it from overheating. Therefore, making it a critical component in the vehicle as failure to replace may damage the engine and other critical parts due to overheating which can leave you stranded on the road. This housing also includes a sensor for a complete replacement.
