Removal and Installation
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS before performing repairs or
service.
1. Disconnect the negative cable from the battery.
2. From under the hood, open the clamp, then disconnect the heater valve cable from the heater valve arm. Turn the heater valve arm to the fully
opened position as shown.
3. When the engine is cool, drain the engine coolant from the radiator.
WARNING: Do not remove the radiator cap when the engine is hot; the engine coolant is under pressure and could severely scald you.
4. Disconnect the heater hoses from the heater unit.
CAUTION: Engine coolant will damage paint. Quickly rinse any spilled engine coolant from painted surfaces.
NOTE: Engine coolant will run out when the hoses are disconnected; drain it into a clean drip pan.
