The cooling system of tight type turns on the pump, a radiator, a broad tank, the electric fan of a radiator and the thermostat. At start of the cold engine cooling liquid circulates only round the engine. Heated cooling liquid passes through a radiator of a heater and comes back to the water pump. Intake of cooling liquid through a radiator is closed that provides the closed thermostat. When cooling liquid reaches the predetermined temperature, the thermostat opens and hot cooling liquid passes through a hose to a radiator. As cooling liquid passes through a radiator, there is its cooling with a stream of counter air. The electric fan of a radiator installed behind a radiator copes the thermal sensor. On models with the air conditioning system the second fan of a radiator is installed. In addition to the ordinary sensor of the index of temperature of cooling liquid temperature sensors for ensuring work systems of injection of fuel and system of ignition are installed.
