5. Cooling system, heating and ventilation
The cooling system of tight type turns on water the pump with the drive from a gear belt, the electric fan of a radiator, a radiator, a broad tank, the thermostat and a radiator of a heater, and also hoses and switches. At start of the cold engine cooling liquid circulates around the block of cylinders and a head of the block of cylinders. Warm cooling liquid passes through the heater fan to the water pump. As cooling liquid when heating extends, its level in a broad tank increases. 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. However if temperature of cooling liquid begins to exceed a certain value, the thermal sensor of a radiator turns on the electric fan which increases a stream of the air passing through a radiator. At reduction of temperature of cooling liquid below the predetermined value the thermal sensor of a radiator switches off the electric fan therefore the krylchatka of the fan of a radiator rotates freely.
