Information - Heater/cooling system

Internal combustion engine requires a cooling system in order to prevent damage and breakage caused by high temperatures. Almost all cars use liquid cooling. As a coolant a mixture of antifreeze and water is used. This prevents its freezing at low ambient temperatures. Water coolant is located in front and consists mostly of aluminium. In old cars it is made of brass. Air flow provides cooling of the fluid. The fan provides necessary air supply when the car is in the stationary state and at low speed.

The water pump pumps the coolant into the cooling circuit. Engine cooling system is controlled by a thermostat that controls the valve. When the temperature exceeds a certain mark (about 75 ° C), the valve opens. If this is not sufficient and the temperature reaches the following limit (90 ° C), the fan starts. The system includes an expansion tank to control the expansion of the coolant when the temperature increases.

Damage of the cooling system often affects the density of the coolant. If there remain sports under the car, it is necessary to search the leakage. If the temperature reaches the red mark, stop the car immediately to avoid engine damage. You can continue driving when the temperature downs.

The engine heat is also used to heat the vehicle. With the help of the heat exchanger heat is used to heat the air. Internal unit fan feeds warm air to the car salon. The heating system works particularly fast when using air circulation. The air from the salon then passes the same way through the heat exchanger. Since this secondary air has a higher temperature than the air in the street, the heating process is accelerated.
