REMOVAL & INSTALLATION
See Figure 1
- Drain the cooling system into a suitable container.
When draining the coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze, and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
- Remove the bench seat behind the driver's front seat. Refer to Routine Maintenance 0 for a detailed procedure.
- Remove the service panel from the interior panel on the driver's side of the vehicle.
- Unfasten the attaching screws and remove the floor duct by rotating it carefully downward.
- Remove the heater core cover screws and lift out the cover.
- Disconnect the heater hoses at the core tubes. Place rags below the core to catch any coolant which may spill out after the clamps are removed. Inspect the hose and replace if cracked or soft to the touch.
- Slide the core and seal from the case. Remove the seal and discard.
- Slide the heater core in to the case. Install a new seal around the edge of the case, then install the case cover.
- Secure the case sections together by installing the retaining screws around the case edges.
- Install and clamp the heater core hoses to the heater core tubes.
- Install the floor duct and secure with screws.
- Install the side service panel, followed by the rear bench seat.
- Fill the cooling system and bleed.
- Start the vehicle and allow to reach normal operating temperature. Turn the heat on and make sure it works properly.
