General information and device
The air intake for interior heating occurs through the air intake grille with an anti-dust filter, located under the windshield. Outside air passes through the dust filter (air cleaner) and enters the fan casing, and from there - into the heater radiator, from where, already in a heated state, through the air distribution dampers it enters the deflectors in the cabin.
Depending on the position of the heater regulator, a larger or smaller amount of outside air is drawn through the heater core. The heater core is located inside the heater housing and is heated by hot coolant flowing through the heater. The air heated in the heater radiator is supplied to the passenger compartment. The temperature of the air supplied to the passenger compartment is controlled by mixing fresh outside air and heated air in the heater using an air distribution damper.
A fan is installed to increase the volume of air supplied for interior heating. The fan can work with different intensity (speed), which is provided by the appropriate resistors installed on the fan connection board. In the event of a malfunction, the board is replaced as a set (see illustration 9.0, 9.0a and 9.0b).
