5.2. General information



When opening a cover of a broad tank on the hot engine it is necessary to be careful, as leaving pairs can lead to strong burns. For this purpose close a cover of a broad tank a thick layer of a fabric and slowly unscrew a cover before emergence of a 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 quantity of water.

The system of cooling of tight type turns on the water pump with a drive from a gear belt, the electric fan of a radiator, a radiator, a broad tank, the thermostat and a heater radiator, and also hoses and switches. At start of the cold engine I cool shchy liquid circulates round 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 raises. Intake of cooling liquid through a radiator is closed that provides the closed thermostat. When cooling liquid will reach 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 by a stream of counter air. However if the temperature of cooling liquid starts to exceed a certain value, the temperature-sensitive element 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 a temperature-sensitive element of a radiator switches off the electric fan therefore the krylchatka of the fan of a radiator rotates freely.
