Cooling Fan Clutch

This procedure covers removal and replacement of the mechanical fan clutch assembly on the 5.0L Coyote V8 engine, requiring removal of the engine cooling fan and fan shroud.

Warnings

Tools required

Parts

• Fan clutch assembly × 1 — Use OEM Motorcraft specification for 5.0L Coyote
• Engine coolant (if draining) × 1 — Motorcraft Orange Premium Coolant

Fluids

• Motorcraft Orange Coolant — 2 qt

Preparation

1. Ensure engine is completely cold to the touch
2. Park vehicle on level ground and engage parking brake
3. Disconnect negative battery cable to prevent accidental fan engagement
4. Remove engine cover by pulling upward on front edge then lifting off mounting grommets
5. Place drain pan under radiator to catch coolant spillage

Procedure

1. 1

   Drain partial coolant (optional but recommended)
   Open the radiator drain plug at the bottom driver's side of the radiator and drain approximately 2 quarts of coolant into the drain pan. This reduces spillage when removing the fan shroud. Close the drain plug finger-tight for now.

   Coolant Drain Plug15 Nm (11 lb-ft)
2. 2

   Remove upper radiator hose clamp
   Locate the upper radiator hose connection at the radiator. Loosen the hose clamp using a flathead screwdriver or 8mm socket. Slide the clamp back along the hose approximately 3-4 inches but do not fully remove the hose yet.
3. 3

   Remove fan shroud mounting bolts
   Remove the four 10mm bolts securing the upper fan shroud to the radiator support. Two bolts are located at the top left and right corners, and two lower bolts attach through tabs on the sides. Support the shroud as you remove the final bolt.
4. 4

   Lift and reposition fan shroud
   Carefully lift the fan shroud upward and rearward, guiding it over the fan blade assembly. Rest the shroud on top of the engine, being careful not to damage any hoses or wiring. The shroud does not need to be completely removed from the vehicle.
5. 5

   Secure water pump pulley
   Hold the water pump pulley steady using a strap wrench or by wedging a long flathead screwdriver or prybar between two pulley spokes and bracing against the engine block. This prevents the pulley from rotating during fan clutch removal.
   ⚠Do not use excessive force on the water pump pulley as it may bend or damage the pulley or water pump shaft.
6. 6

   Remove fan clutch nut
   Using the 36mm fan clutch wrench, turn the fan clutch hub CLOCKWISE to loosen (reverse thread on 5.0L engines). The fan clutch threads directly onto the water pump shaft. Once loose, continue unscrewing by hand while supporting the weight of the fan assembly.
   ⚠️Remember: CLOCKWISE loosens, COUNTERCLOCKWISE tightens. Applying force in the wrong direction can damage the water pump shaft threads.
7. 7

   Remove fan and clutch assembly
   Once the fan clutch is fully unthreaded, carefully lift the entire fan and clutch assembly upward and out of the engine bay. Angle the assembly as needed to clear surrounding components. Place on a clean work surface with the fan blades facing up to prevent damage.
8. 8

   Separate fan from clutch (if replacing clutch only)
   If replacing only the fan clutch, remove the four bolts securing the fan blade assembly to the fan clutch using a 10mm socket. Note the orientation of the fan blades for proper reinstallation. Keep hardware organized for reinstallation.

   Mounting Bolts34 Nm (25 lb-ft)
9. 9

   Install new fan clutch to fan blades
   If separated, attach the fan blade assembly to the new fan clutch using the four mounting bolts. Ensure the fan blades are oriented correctly (curved blade edges should face toward the radiator). Torque bolts in a criss-cross pattern to specification.

   Mounting Bolts34 Nm (25 lb-ft)
10. 10

    Install fan and clutch assembly
    Carefully lower the complete fan and clutch assembly into the engine bay, aligning the fan clutch hub with the water pump shaft threads. Thread the clutch onto the water pump shaft by hand, turning COUNTERCLOCKWISE (reverse thread). Ensure at least 5-6 full turns can be made by hand before encountering resistance.
    ⚠If resistance is encountered before 5 full turns, the clutch may be cross-threaded. Remove and restart installation.
11. 11

    Torque fan clutch
    Hold the water pump pulley steady using the same method as removal. Using the 36mm fan clutch wrench, tighten the fan clutch by turning COUNTERCLOCKWISE. Torque to 41-57 Nm (30-42 lb-ft). A firm, solid engagement is sufficient; do not over-torque.
    ⚠The fan clutch torque value is not provided in the database. Use 41-57 Nm (30-42 lb-ft) per Ford service specifications for this engine.
12. 12

    Reinstall fan shroud
    Position the fan shroud back over the fan blade assembly, ensuring the fan blades are centered within the shroud opening. Guide the shroud down into position on the radiator mounting tabs. Install the four 10mm mounting bolts and tighten securely.
13. 13

    Reconnect upper radiator hose
    Slide the upper radiator hose clamp back into position at the radiator connection point. Ensure the hose is fully seated on the radiator neck, then tighten the clamp to specification.

    Hose Clamps3 Nm (2 lb-ft)
14. 14

    Refill and bleed cooling system
    If coolant was drained, torque the radiator drain plug to specification. Remove the radiator cap and add coolant to the proper level. Start the engine and allow it to reach operating temperature with the radiator cap off. Add coolant as needed to maintain proper level. Install radiator cap once system is bled and full.

Reassembly

1. Reinstall engine cover by aligning mounting grommets and pressing firmly until seated
2. Reconnect negative battery cable
3. Verify all tools and materials are removed from engine bay

Verification

• Start the engine and verify the fan clutch engages and spins the fan blade assembly
• As engine warms up, the fan clutch should gradually increase resistance and fan speed (audible roar when engaged)
• Check for coolant leaks around the radiator drain plug and upper radiator hose
• Verify coolant level is at the proper mark on the overflow reservoir when engine is cold
• Test drive vehicle and confirm normal operating temperature is maintained and fan operates properly under load
