Cooling system
While the engine is cold, coolant circulates only in the head and engine block heater and the heat exchanger interior. With increasing temperature, the coolant thermostat opens the large cooling circuit. The coolant is directed through the radiator constantly working pump. The liquid passes downwards through the radiator and is cooled by air passing therethrough.
Heater and ventilation
The heater consists of a fan and heat exchanger disposed in the blocks of the front and rear portions of the cabin. Hot coolant passes through the heat exchangers. When you move the control handle mode heater, located in the Control Panel, open the valve, and the hot air begins to flow into the interior of the vehicle. If you turn on the heater fan, air is supplied to the interior force.
Intake air before getting into the interior, passes through the filter (refer to Chapter Routine maintenance). The main share of the dust particles settle in the filter. Observe the filter change intervals. Littered with dust filter will restrict air flow into the interior, leading to stagnation of air inside the passenger compartment.
Air distribution system by means of ventilation flaps. The mode of air circulation. The flaps are controlled by servos.
