Preventions

When opening a cover of a broad tank on the hot engine it is necessary to be careful as the coming-out hot vapors can lead to severe burns.

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.

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

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 around the block of cylinders, a head of the block and a final collector. Warm cooling liquid passes through a radiator of a heater and comes back 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. The electric fan of cooling of a radiator installed behind a radiator is run by the thermal sensor located in a radiator. Dopolnitel but to the ordinary sensor of the index of temperature of cooling liquid temperature switches and sensors for ensuring work of system of injection of fuel and system of ignition are installed.
