| THE GENERAL DATA |
The system of cooling of tight type includes the pump, an aluminium radiator, a broad tank, the electric fan of a radiator and the thermostat. At start of the cold engine the cooling liquid circulates round the block of cylinders, a head of the block and a final collector. The warm cooling liquid passes through a radiator of a heater and comes back to the water pump. As the cooling liquid at heating extends, its level in a broad tank raises. Receipt of a cooling liquid through a radiator is closed that provides the closed thermostat. When the cooling liquid reaches the predetermined temperature, the thermostat opens also a hot cooling liquid passes through a hose to a radiator. As the cooling liquid passes through a radiator there is its cooling by a stream of counter air. The electric fan of cooling of the radiator, established behind a radiator, copes the thermal gauge located in a radiator.
In addition to the usual gauge of the index of temperature of a cooling liquid, temperature switches and gauges for maintenance of work of system of injection of fuel and ignition system are established.
On models with the diesel engine of 2,0 l the additional thermostat has been originally established on the left side of the block of cylinders on an exit to an oil radiator. However on later models this thermostat is not established.
