Removal/Replacement

CAUTION:
- All SRS electrical wiring harnesses are covered with yellow outer insulation.
- When disconnecting the SRS wire harness, install the short connector on the airbag, then disconnect the wire harness.
- Replace the entire affected SRS harness assembly if there is an open circuit or damage to the wiring.

1. When the engine is cool, drain the coolant from the radiator.

WARNING:
- Do not remove the radiator cap when the engine is hot; the coolant is under pressure and could severely scald you.
- Keep hands away from the radiator fan. The fan may start automatically without warning and run for up to 30 minutes, even after the engine is turned off.

CAUTION: Radiator coolant will damage paint. Quickly rinse any spilled coolant from painted surfaces.







2. Disconnect the heater hoses at the heater.

NOTE: Coolant will run out when the hoses are disconnected, drain it into a clean drip pan.

3. Disconnect the heater valve cable from the heater valve.
4. Remove the dashboard.
5. Remove the heater duct.







6. Remove the dashboard support tube.
7. Remove the heater mounting nuts (4), then remove the heater assembly.
8. Install in the reverse order of removal, and:
- Apply sealant to the grommets.
- Do not interchange the inlet and outlet hoses. Make sure that the hose clamps are secure.
- 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.
- Connect all cables and make sure they are properly adjusted.
