Heater Core: Service and Repair

Heater Core, Removing And Installing







- Remove heating and A/C unit.
- Remove screws -C-.
- Depress tabs -B- and pull (lift) heater core -A- from housing.

Notes on installing:
- When installing heater core, always secure it in the heater flap housing with two suitable screws -C- (e.g. self-tapping screws, 3.2 x 20 mm). This also applies even if the heat exchanger was originally only clipped in place.
- The heater core is installed in the heater flap housing without an all-round seal.







- Replace seal -A- and ensure it is properly seated against contact surface -C-.
- Reattach coolant hoses according to coolant flow direction indicated on heater core. Reference heater core/coolant flow configurations.
- Heater core configuration without quick-connect couplings illustrated here (coolant flow direction -arrow B-).
