Rear Heater Core Replacement

SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ) and the precautions and procedures (see PRECAUTIONS AND PROCEDURES ) before doing repairs or service.

1. When the engine is cool, drain the engine coolant from the radiator (see COOLANT CHECK ).
2. Remove the center console (see CENTER CONSOLE REMOVAL/INSTALLATION ).
3. Slide the hose clamps (A) back, then disconnect the rear inlet heater hose (B) and the rear outlet heater hose (C) from the rear heater core. Note the orientation of the hose.

   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.

   • Make sure that there is no coolant leakage.
   • Make sure that there is no air leakage.
