Tools you'll likely need:
* Pulley puller: This is the most crucial tool. You'll need a puller specifically designed for power steering pump pulleys. The type depends on the pulley's design (two or three bolt, etc.). A gear puller might work, but a dedicated pulley puller is preferred.
* Sockets and wrenches: To remove any retaining bolts or nuts.
* Penetrating oil (like PB Blaster): To help loosen any seized parts.
* Torque wrench: For properly tightening bolts during reassembly.
* Pry bar (optional): Might be helpful in combination with the puller, but use with caution.
* Hammer (optional): Only use a soft-faced hammer if absolutely necessary and with extreme caution to avoid damaging the pump.
Procedure:
1. Prepare the area: Work in a clean, well-lit space. Have your tools organized and ready.
2. Disconnect the belt: Remove the serpentine belt to access the pulley. Consult your vehicle's repair manual for the proper procedure. This usually involves loosening the tensioner pulley.
3. Inspect the pulley: Look for any retaining bolts or nuts on the pulley itself. Some pulleys have a nut on the shaft, while others may have bolts on the pulley face.
4. Apply penetrating oil: Liberally spray penetrating oil on any bolts or the pulley shaft. Let it soak for at least 15-20 minutes. This significantly increases your chances of removing the pulley without damage.
5. Remove retaining bolts/nut (if any): If there are any retaining bolts or a nut, remove them carefully using the appropriate socket or wrench.
6. Use the pulley puller: This is where the pulley puller comes in. Position the puller according to the manufacturer's instructions and securely attach it to the pulley. Slowly and steadily apply pressure to the puller until the pulley comes off. Avoid using excessive force, as this could damage the pump shaft or pulley.
7. Clean: Once the pulley is removed, clean the pulley and the power steering pump shaft to remove any debris or old sealant.
8. Inspect the pump shaft: Check the power steering pump shaft for any damage. If it's bent or damaged, you will need to replace the pump.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 1995 Chevy Silverado is invaluable. It will provide detailed instructions and diagrams for your specific model.
* Replace parts if necessary: If any components are damaged during removal (pulley, shaft, etc.), replace them.
* Professional help: If you're uncomfortable performing this task yourself, take your vehicle to a qualified mechanic. This is a relatively involved process, and improper removal can damage the power steering pump, leading to more expensive repairs.
This procedure is a general guideline. The exact steps may vary depending on the specific design of your power steering pump and pulley. Always refer to a repair manual for your vehicle to ensure you're following the correct procedure.
