This procedure covers the replacement of the power steering pump on a 2015-2020 Ford F-150 with the 5.0L Coyote V8 engine, including serpentine belt removal, pump removal, and system bleeding.

Warnings

Tools required

Parts

• Power steering pump × 1 — Use OEM specification
• Power steering pump O-rings × 1 — Included with pump or purchase separately
• Motorcraft MERCON LV ATF × 1 — XT-10-QLVC

Fluids

• Motorcraft MERCON LV ATF — 1.5 qt

Preparation

1. Park vehicle on level ground and engage parking brake
2. Allow engine to cool completely (minimum 2 hours)
3. Disconnect negative battery terminal and wait 2 minutes
4. Place drain pan under power steering pump area
5. Remove engine cover by pulling upward on cover (press-fit clips)
6. Use fluid transfer pump to remove power steering fluid from reservoir if accessible, or prepare for fluid drainage

Procedure

1. 1

   Document serpentine belt routing
   Take a clear photo of the serpentine belt routing or verify against the belt routing diagram on the fan shroud. The 5.0L Coyote uses a single serpentine belt that drives the power steering pump, alternator, water pump, and A/C compressor.
2. 2

   Remove serpentine belt
   Locate the spring-loaded belt tensioner on the front of the engine. Using a 1/2" breaker bar or serpentine belt tool, rotate the tensioner clockwise to release tension. Slip the belt off the pulleys and slowly release the tensioner. Remove the belt from the engine bay. Inspect the belt for wear and replace if needed.
3. 3

   Disconnect power steering pressure line
   Locate the high-pressure line fitting on the pump (typically on the rear of the pump body). Using a line wrench, loosen the pressure line fitting. Be prepared for residual fluid to drain. Allow fluid to drain into the catch pan. Once drained, completely remove the pressure line and cap or plug the line to prevent contamination.

   Pressure Line Fitting30 Nm (22 lb-ft)
4. 4

   Disconnect power steering return line
   Locate the return line connection (typically a hose with clamp or threaded fitting). If equipped with a hose clamp, use pliers or a screwdriver to loosen the clamp and slide it back. Pull the return hose off the pump fitting. If equipped with a threaded fitting, use a line wrench to disconnect. Allow remaining fluid to drain into the catch pan.

   Return Line Clamp4 Nm (3 lb-ft)
5. 5

   Remove pump mounting bolts
   Locate the power steering pump mounting bolts. On the 5.0L Coyote, there are typically 3 mounting bolts securing the pump to the front engine bracket. Remove all mounting bolts using the appropriate socket. Support the pump while removing the final bolt to prevent it from falling.
   Torque spec

   Pump Mounting Bolts25 Nm (18 lb-ft)
6. 6

   Remove power steering pump
   Carefully maneuver the power steering pump out of the engine bay. You may need to rotate or tilt the pump to clear surrounding components. Once removed, place the pump on a clean work surface with the fittings facing upward to minimize fluid leakage.
7. 7

   Prepare new power steering pump
   Remove the new pump from packaging. Verify all O-rings are properly installed on the new pump fittings. If O-rings are provided separately, install new O-rings on both the pressure fitting and return fitting. Lightly lubricate the O-rings with clean ATF. Compare the new pump to the old pump to verify correct part number and pulley alignment.
8. 8

   Install new power steering pump
   Position the new pump into the mounting bracket, aligning the mounting bolt holes. Thread all mounting bolts by hand first to ensure proper alignment. Once all bolts are started, torque the mounting bolts in a star pattern to the specified torque value.

   Pump Mounting Bolts25 Nm (18 lb-ft)
9. 9

   Connect power steering lines
   Connect the return line to the pump first. If using a hose clamp, ensure the hose is fully seated on the fitting before positioning and tightening the clamp. Connect the high-pressure line to the pump using a new O-ring. Thread the fitting by hand first, then torque to specification using a line wrench.

10. 10

    Reinstall serpentine belt
    Route the serpentine belt according to the diagram documented earlier or the routing diagram on the fan shroud. Start with the belt on the crankshaft pulley, then route around all accessories. Use the breaker bar to rotate the tensioner and slip the belt onto the final pulley. Verify the belt is properly seated in all pulley grooves.
11. 11

    Fill power steering system
    Fill the power steering reservoir with Motorcraft MERCON LV ATF to the cold fill line (do not overfill). Start with approximately 1 quart and add as needed during bleeding process.
12. 12

    Bleed power steering system
    With the engine off, turn the steering wheel fully from lock to lock 10 times slowly. Check fluid level and add as needed. Reconnect the battery. Start the engine and let it idle. Turn the steering wheel slowly from lock to lock 5 times while the engine is running. Check for leaks at all connections. Top off fluid to the hot fill line. Listen for any whining or unusual noises indicating air in the system.

Reassembly

1. Reinstall engine cover by aligning clips and pressing firmly until seated
2. Verify all tools and parts have been removed from engine bay
3. Double-check all line connections for tightness and leaks
4. Clean any spilled fluid from engine and surrounding components

Verification

• Start the engine and verify no leaks at pump connections while engine is idling
• Turn steering wheel fully from lock to lock while idling and verify smooth operation with no whining or groaning
• Check power steering fluid level with engine at operating temperature and add if necessary
• Test drive vehicle and verify normal power steering assist at various speeds
• After test drive, recheck fluid level and inspect for any leaks in the engine bay
• Verify serpentine belt is properly seated and tracking correctly on all pulleys
