• One of the car parts that, in addition to allowing the engine to quickly heat up, controls the engine's temperature.
For proper operation of the engine, the temperature should be at a certain level. The thermostat is a mechanical device for adjusting the temperature of the motor engine. This device automatically maintains the motor's heat by about 85 degrees.
The thermostat closes the water inlet to the radiator and the water runs through the engine's path and does not enter the radiator until it reaches 85 degrees. In this case, the heat activates the thermostat and the mercury that expands inside the thermostat. It will open the water flow to the radiator so that it does not go up in heat and the thermostat is closed again as the temperature drops. This continuous operation is repeated to keep the engine warm at ideal temperature.
In the winter, the water entering the radiator is cooled to a heat exchanger and is used to heat it inside the car.
