The cooling system ensures engine operation at optimal temperature conditions.
The system consists of a radiator and coolant circulation channels, fans, thermostat, coolant pump and its drive system. The coolant pump is driven by a timing belt
Radiator
The engine is equipped with an aluminum radiator. On versions with automatic transmission, the transmission fluid cooling system pipe passes through the left radiator tank.
Expansion tank
The expansion tank is a plastic container into which the coolant flows when it expands. Air from the cooling system also flows into the expansion tank. When the coolant cools down, it flows back into the radiator. When the engine is not running and is cold, the coolant level should be between the MIN and MAX marks
Coolant pump
The system uses a centrifugal pump. The pump is driven by the timing belt. The pump is a non-disassemblable element and is not subject to maintenance.
Thermostat
The system uses a wax-type thermostat. The thermostat is installed in the cylinder head.
When the engine warms up, the thermostat remains closed and the coolant circulates in a small circle, which allows the engine temperature to reach the optimum value as quickly as possible. As the temperature increases, the thermostat opens and the coolant begins to circulate through the radiator, which allows the engine temperature to be maintained within the operating range.
The thermostat valve begins to open at a temperature of 87°C, opens fully at a temperature of 102°C and closes at a temperature of 86°C.
Coolant temperature sensor
The system uses a thermistor, which provides information about the coolant temperature to the light indicator on the instrument panel and the electronic engine control unit.
Engine warm-up
The car is equipped with an engine heating system, which facilitates engine starting in cold weather and accelerates engine warm-up.
Fan
The version without air conditioning is equipped with a fan with a diameter of 300 mm, and the version with air conditioning - 366 mm. The fan has five blades. The electric motor is mounted on the fan casing. The operation of the fan is controlled by an electronic engine control unit.
