Overhaul

1. Remove the heater assembly (page 21-21).
2. Remove the screws (2) and heater core cover.
3. Remove the screw and pipe clamp.
4. Remove the screw and damper arm.
5. Pull the heater core from the heater housing.
NOTE: Be careful not to bend the inlet and outlet pipes during heater core removal.

Install the removed parts in the reverse order of removal and:
Loosen the bleed bolt on the engine and refill the radiator and reservoir tank with the proper coolant mixture. Tighten the bleed bolt when all the trapped air has escaped and coolant begins to flow from it.
