### Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the battery negative cable.
2. Remove the upper radiator covers:

• | Release the self-locking tabs.

• | Remove the cover screws.

• | Remove the covers.

3. Drain the engine coolant. Refer to Cooling System Draining and Filling .
4. Remove the intake air resonator chamber. Refer to Intake Air Resonator Replacement in Engine Controls.
5. Disconnect the electrical connectors at the following locations:

• | The primary cooling fan

• | The cooling fan control switches

6. Remove the radiator air bleed hose from the radiator.
7. Remove the transmission oil cooler pipe fittings and seals from the radiator.
8. Position the pipes away from the radiator.
9. Remove the coolant hose from the secondary auxiliary coolant pump.
10. Remove the secondary AIR cut-off valve bracket bolts from the fan housing.
11. Remove the condenser-to-radiator bracket bolts (1).
12. Remove the radiator inlet/outlet hoses from the radiator.
13. Disconnect the secondary auxiliary coolant pump connector.
14. Lift and rock the radiator and primary fan together in order to unseat the upper and lower retainers.
15. Remove the radiator and the primary fan together from the radiator support.
16. Remove the primary fan bolts, if necessary.
17. Remove the primary fan from the radiator.
18. Remove the cooling fan control switches, if necessary.

### Installation Procedure

1. Install the cooling fan control switches, if removed.
2. Install the primary fan to the radiator, if removed:

• | Engage the tab.

• | Install the bolts.

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.

Tighten
Tighten the bolts to 4 N·m (35 lb in).

3. Install the radiator and primary fan together to the radiator support:

• | Engage the upper retainers in the radiator support brackets.

• | Engage the tabs on the bottom of the radiator in the lower retainers.

4. Connect the secondary auxiliary coolant pump connector.
5. Install the radiator inlet/outlet hoses to the radiator.
6. Install the condenser-to-radiator bracket bolts (1) until fully seated and not stripped.
7. Install the secondary AIR cut-off valve bracket to the fan housing.
8. Install the bracket bolts.

Tighten
Tighten the bolts to 4 N·m (35 lb in).

9. Install the coolant hose to the secondary auxiliary coolant pump.
10. Install the transmission oil cooler pipe fittings and seals to the radiator.
