Thermostat

The thermostat allows coolant to move from the engine through the radiators. The thermostat is installed inside a housing which is placed in the hose which enters the top of the engine.



When the coolant temperature is low, the thermostat valve is closed, keeping the coolant inside the engine. This allows the engine to quickly reach the correct operating temperature during cold weather.

When the coolant temperature rises to 70 degrees Celsius, the thermostat valve opens, allowing the coolant to circulate through the radiators, cooling the engine.
