Overhaul

Heater Unit Overhaul:

1. Remove the heater unit.
2. Remove the two screws 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 unit.

NOTE: Be careful not to bend the inlet and outlet pipes during heater core removal.

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