Tools and materials needed:
- Socket wrench set
- Flathead screwdriver
- Pliers
- New power steering pump pulley
- Replacement serpentine belt (optional)
Procedure:
1. Park the vehicle on level ground, apply the parking brake, and turn off the engine. Allow it to cool down if the vehicle was recently in operation.
2. Locate the power steering pump pulley. It is usually situated near the front of the engine, on the driver's side.
3. Remove the serpentine belt. To do this, use a flathead screwdriver to depress the tensioner pulley and loosen the serpentine belt. Slide the belt off the power steering pump pulley.
4. Unbolt the power steering pump pulley. There are usually four bolts securing the pulley. Use a socket wrench to loosen these and remove them.
5. Remove the old pulley by gently prying it off the shaft using a pry bar or flathead screwdriver. Be careful not to damage the shaft or the surrounding components.
6. Install the new power steering pump pulley onto the shaft. Make sure that the new pulley is properly seated and aligns correctly with the other pulleys.
7. Replace the bolts that hold the pulley in place and tighten them securely.
8. Reinstall the serpentine belt. Route it around the power steering pump pulley and other pulleys, then use the tensioner to adjust the belt tension.
9. Start the engine and check for proper functioning. Turn the steering wheel back and forth to ensure the power steering pump is working smoothly.
10. Test drive the vehicle to ensure the new pulley and serpentine belt are operating correctly with no unusual noises or vibrations.
Note: When replacing a belt or component near your engine, it's important to check or consider changing your belts (especially timing belt) and hoses while you are already performing this repair in case anything else might give out, since many of these items should be replaced roughly around the same time.
