Steps
- Remove the intake hose
With the engine cool, loosen the intake-hose clamps and remove the air-box Torx fastener. Lift the hose and air-box section away without allowing debris into the intake.
- Relieve belt tension and remove the belt
Review the belt-routing diagram and note the path. Turn the tensioner with a 15 mm socket, slip the belt off a pulley, and release the tensioner slowly before removing the belt.
- Free the fan clutch and shroud
Loosen the fan-to-clutch bolts enough to hold the assembly, then use the fan-clutch wrench and adjustable wrench to release the clutch from the pump shaft. Remove the bolts, disconnect the fan wiring, release the shroud clip, and lift the assembly out carefully.
- Install the replacement fan clutch
Orient the fan and harness as on the original assembly and lower them into the shroud. Reconnect the wiring and clip, fasten the fan to the clutch, then thread the clutch onto the pump in the specified direction and tighten it to the manufacturer procedure.
- Reinstall the belt and intake hose
Route the serpentine belt according to its diagram and release the tensioner gradually. Refit the intake hose and secure its clamps and Torx fastener, checking that wiring and hoses clear the fan.
- Verify fan operation
Start the engine and observe the fan from a safe distance. Confirm the fan clutch responds normally, the belt tracks correctly, and no wiring or shroud contacts the blades.
