Steps
Disconnect the battery and remove bumper cover
With the engine cool, disconnect the negative battery cable. Release the upper, wheel-well, and lower bumper fasteners, then pull the cover forward without straining its clips.
Remove the battery
Disconnect the positive cable, remove the hold-down and cover, then lift the battery out. Keep the terminals from contacting metal.
Move the coolant reservoir
Unbolt the overflow bottle and disconnect its hose carefully. Keep a drain pan ready and prevent coolant from spilling onto nearby electrical parts.
Remove the radiator fan
Disconnect the fan and temperature-sensor wiring. Loosen the coolant hose clamp, disconnect the hose, and lift the radiator fan assembly out of its mounts.
Remove the A/C condenser fan
Unplug the condenser fan, remove its fasteners and supporting brackets, and release the hose clip from the fan frame. Lift the fan out without opening any refrigerant lines.
Install the replacement condenser fan
Position the new fan, reconnect its wiring, and secure the hose clip and brackets. Tighten the fan and condenser fasteners evenly, keeping wiring clear of the blades.
Reinstall the radiator fan and reservoir
Lower the radiator fan into its mounts, reconnect the sensor and fan plugs, then reconnect the coolant hose and ground wire. Refit the overflow bottle and its hose.
Reinstall battery and bumper
Secure the battery, reconnect the positive cable and then the negative cable, and refit its covers. Reinstall the bumper cover and all liner clips, checking that no wiring is pinched.
Test both cooling fans
Start the vehicle and confirm the radiator fan operates when commanded. Turn on the A/C to check condenser fan operation, then inspect coolant level and hose connections after cooling.
Check your vehicle’s repair manual for exact specifications and fit.
