Until the engine is heated-up, cooling liquid circulates only in a head and the block of cylinders and in the heat exchanger of a heater of salon. At increase of temperature of cooling liquid the thermostat opens a big contour of cooling. Cooling liquid goes through a radiator constantly working pump. Liquid passes through a radiator from top to down and is cooled with the air passing through it.

System of heating and ventilation

The system of heating consists of the fans and heat exchangers located in blocks of forward and back parts of salon. Hot cooling liquid passes through heat exchangers. When moving the handle of management of the modes of a heater located on the control panel valves open and hot air begins to come to interior of the car. If to turn on the heater fan, air will move in salon forcibly.

Intaking air before getting to salon, passes through the filter (address the Head Routine maintenance). The main share of particles of dust will settle in the filter. It is necessary to observe frequency of replacement of the filter. The filter blocked by dust will limit air supply in salon that will lead to an air stagnation in salon.

Distribution of streams of air of system of ventilation is carried out by means of gates. The air circulation mode is provided. Gates are operated with the help of servo-drivers.
