Heating system heat exchanger, function - GF83.20-P-2101-01P

Function 

The heated coolant flows through the heating system heat exchanger separately for the left and right side.

Coolant flows continuously through the heating system heat exchanger. The control, depending on the heating output request, takes place only by means of the position of the blend air flaps, using the left blend air flap actuator motor (M2/6) and the right blend air flap actuator motor (M2/7).

The heat is conducted to the outside via the coiled pipes and lamella. This in turn warms the passing air flow, which is directed to the vehicle interior via the various defroster, ventilation and heater vents.
