Rear Heater Core Replacement (Rear Heater - A/C)
Rear Heater Core Replacement
1. When the engine is cool, drain the engine coolant from the radiator.
2. Remove the center console.
3. Slide the hose clamps (A) back, then disconnect the inlet heater hose (B) and the outlet heater hose (C) from the rear heater core. Engine coolant
will run out when the hoses are disconnected; drain it into a clean drip pan. Be sure not to let coolant spill on the electrical parts or the painted
surfaces. If any coolant spills, rinse it off immediately.
4. Remove the self-tapping screws and the clamps (A). Carefully pull out the rear heater core (B) so you don't bend the inlet and outlet pipes.
5. Install the heater core in the reverse order of removal, and note these items:
-
Do not interchange the inlet and outlet heater hoses, and install the hose clamps securely.
-
Refill the cooling system with engine coolant.
-
Make sure that there is no coolant leakage.
