Difficulty: Intermediate · About 40 min · Ford Ranger

Replace the power steering pump pulley on a Ford Ranger 4.0L by recording belt routing and checking that the pulley seats squarely.

Steps

1. Remove the intake tube

   Remove the throttle-body cover fasteners and move the cover aside. Disconnect the intake tube from the throttle body, mass airflow sensor, and breather hose.

2. Release the serpentine belt

   Photograph the belt routing, then rotate the tensioner with a 3/8-inch ratchet to release tension. Slip the belt off the alternator and return the tensioner slowly.

3. Remove and replace the pulley

   Remove the pulley fasteners and pull the pulley from the pump shaft. Position the replacement squarely and tighten its fasteners evenly to the vehicle specification.

4. Route and inspect the belt

   Follow the belt diagram to route the belt around each pulley. Move the tensioner, seat the belt on the final pulley, release tension slowly, and confirm every rib is aligned.

5. Reinstall the intake tube

   Reconnect the intake tube and breather hose, tighten the clamps, and reinstall the throttle-body cover. Start the engine briefly and check for belt noise or tracking issues.

Check your vehicle’s repair manual for exact specifications and fit.
