The cooling system consists of a radiator, a water pump driven by the engine crankshaft and a thermostat. The system is filled with coolant. A fan with an electric motor is installed in the radiator casing, which is switched on by a thermal bimetallic switch.
Tightening torques, Nm
- Fan thermal switch - 30-40
- Temperature sensor - 5-10
- Water pump mounting bolts to cylinder block — 19–31
Caution! The radiator fan may turn on even when the engine is not running, even if the ignition switch is in the "ON" position. When performing any work near the fan, disconnect the negative battery cable.

The water pump is driven by the timing belt and is mounted at the front of the engine. To heat the interior, the coolant is heated when the engine is running. The heated coolant flows through the heater radiator located inside the vehicle. The driver or passenger can control the flow of coolant through the heater radiator and the speed of air flow over the radiator, thereby maintaining the desired temperature in the car's interior. Some vehicles are equipped with an air conditioning system. The main units of this system are installed in the engine compartment; the air conditioning compressor is driven by a belt from the crankshaft pulley.
