Description and Operation

Heater Core and Evaporator Core Housing

The heater core and evaporator core housing contains the blower motor, the pollen filter, the heater core, the evaporator core (on vehicles with air conditioning (A/C)), the electric booster heater (if equipped) and various diverter flaps.

Blower motor

CAUTION:Do not put the blower motor down on the blower motor fan wheel.

To prevent damage to the fan wheel vanes, the fan wheel must not be touched. For this reason, a special tool (412-131) has been introduced for removal and installation of the blower motor. This tool is pushed onto the central shaft in order to lift out the blower motor.

Heater core

The heater core is accessible from the right-hand side of the heater core and evaporator core housing (LHD and RHD). It can be removed and installed with the heater core and evaporator core housing installed. During removal, the coolant pipes of the production heater core must be sawn through. During servicing, a heater core with separate coolant pipes is installed.

Evaporator core

The evaporator core is located on the right-hand side of the heater core and evaporator core housing (LHD and RHD). During servicing, it can only be removed with the heater core and evaporator core housing removed .
