J 42865 Cooling Fan Temperature Switch Socket

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
2. Remove the upper radiator covers:

•	Release the self-locking tabs.

•	Remove the upper radiator cover screws.

•	Remove the upper radiator covers.

3. Drain the cooling system. Refer to Cooling System Draining and Filling .
4. Remove the intake air resonator. Refer to Intake Air Resonator Replacement in Engine Controls - 3.0L (L81).
5. Remove the cooling fan shroud. Refer to Engine Cooling Fan Replacement .
6. Disconnect the cooling fan control switches electrical connectors.



7. Remove the surge tank hose (1) from the radiator.
8. Remove the coolant hose from the secondary auxiliary coolant pump.



9. Remove the condenser-to-radiator bracket bolts (1).
10. Remove the radiator inlet hose clamp from the radiator.
11. Remove the radiator inlet hose from the radiator.
12. Remove the radiator outlet hose clamp from the radiator.
13. Remove the radiator outlet hose from the radiator.
14. Remove the transmission oil cooler to radiator top bolts.
15. Disconnect the secondary auxiliary coolant pump connector.
16. Remove the upper radiator upper mounting retainers.
17. Lift and rock the radiator to unseat lower retainers.
18. Remove the radiator (2) and the transmission oil cooler together from the radiator support.
19. Remove the transmission oil cooler bolts.
20. Remove the transmission oil cooler from the radiator.
21. Use the J 42865 to remove the cooling fan control switches, if necessary.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
