Cooling system General information While the engine is not 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 air passing through it.Heater and ventilation The heater consists of fans and the 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 by modes of the heater, located on the control panel, valves open, and hot air starts to arrive in car salon. If to turn on the heater fan, air will move in salon compulsorily. Intaking air before getting to salon, passes through the filter (address to Head Routine maintenance). The main share of particles of a dust will settle in the filter. It is necessary to observe periodicity of replacement of the filter. The filter littered by a dust will limit supply of air in salon that will lead to an air stagnation in salon. Distribution of streams of air of system of ventilation is carried out with the help a zaslonok. The air circulation mode is provided. Zaslonki cope servo-drivers. |
