Mini Cooper Thermostat With Housing

A vehicle thermostat controls the coolant's flow into the radiator and is a key component in the radiator. Shut the thermostat when the engine not in use. When the engine runs and reaches the working temperature level, a sensor activates within the thermostat, allowing the coolant to pass through the radiator and reduce the temperature such that the engine coolant recirculates through cooling system components. The continuous flow keeps the vehicle's engine at the optimum temperature.

The secret of the thermostat lies in the small cylinder at the equipment's motor side. The cylinders are packed with a wax that begins to melt at 180 degrees F but normally 180 F/82 c. This wax contains a rod fixed to the valve. It spreads and forces the rod out of the chamber as the wax melts, and opens the valve. The wax spreads further, as it moves from a solid to a liquid as well as spreading from the heat.

The radiator is attached by means of hoses to the engine on one side and is, on the other, between the engine and the radiator.
