5.2. General information



When opening a cover of a broad tank on the hot engine it is necessary to be careful as the coming-out vapors can lead to severe burns. For this purpose close a cover of a broad tank a thick layer of fabric and slowly unscrew a cover before emergence of the hissing sound. After the hissing termination slowly unscrew, and uncover a broad tank.

After switching off of the hot engine the radiator fan can turn on.

Do not allow hit of cooling liquid on clothes and a paint and varnish covering of a body. Otherwise wash out a surface a plentiful amount of water.

The cooling system of tight type turns on the water 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 I cool shchy 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 includes электричес a cue the fan which increases a stream of the air passing through a radiator. At reduction of temperature I cool liquid Russian cabbage soup 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.
