How to Take Off a Fan Clutch on a 2005 Ford F-150

Removing the fan clutch on a 2005 Ford F-150 is relatively easy to do as long as you have a few special tools. In order to hold the water pump still, you’ll need a special spanner wrench that rests on both sides of the water pump pulley bolts. In addition to this special spanner wrench, you’ll need a 36 mm fan clutch nut wrench designed to loosen the clutch-to-water pump nut. This job can be somewhat involved, so it’s important to take your time and work as slowly as you need to.

Materials:

8 mm box-end wrench
10 mm box-end wrench
2.25-inch water pump pulley holding wrench
36 mm fan clutch wrench
3/8-inch ratchet
10 mm socket
1/4-inch torque wrench

Instructions:

1. Turn off the engine and open the hood. Disconnect the negative battery terminal from the battery using an 8 mm box-end wrench.

2. Remove the seven push-pin-style retaining clips securing the radiator sight shield — the plastic shield above the radiator — by prying the center out of each piece, using a flat-head screwdriver, then prying each retaining clip from the sight shield. Remove the sight shield.

3. Remove the two 10 mm bolts holding the fan shroud to the vehicle’s frame. Hold the water pump pulley still with 2 1/4-inch fan pulley holding wrench. While holding the water pump pulley still, loosen the clutch-to-water pump nut with a 36 mm fan clutch wrench.

4. Unthread the clutch-to-water pump nut from the water pump. Remove the fan clutch and shroud together as an assembly. Remove the four 10 mm bolts holding the fan clutch to the fan using a 3/8-inch ratchet and a 10 mm socket.

5. Insert the new fan clutch inside the fan and reinstall the four fan clutch retaining bolts. Torque the bolts to 156 in-lbs using a 1/4-inch torque wrench. Place the fan assembly inside the fan shroud and set them in position inside the engine compartment as one unit.

6. Reinstall the two shroud-to-body bolts using a 10 mm box-end wrench. Thread the clutch-to-water pump back onto the water pump by hand. Hold the water pump still using the 2 1/4-inch fan pulley holding wrench. Tighten the clutch-to-water pump nut using the 36 mm fan clutch wrench until it’s fully seated.

7. Reconnect the battery terminal using the 8 mm box-end wrench. Start the engine and confirm that the fan clutch operates properly.

Tips:

Don’t attempt to remove the fan clutch from the water pump without the proper special tools. Using the wrong tools can damage the fan, water pump or even cause an injury.
