The
cooling circuit consists of the
radiator, the
water pump, the coolant and the
radiator fan. Together these
car parts ensure the cooling of the engine. When the engine is switched on, the water thermostat measures the exact temperature in the engine. Depending on the information the thermostat is submitting the
cooling parts start working. When the temperature in the engine reaches a certain level, the cooling parts ensure the temperature is kept constant to avoid overheating and subsequent irreversible damage.
