Here's a general outline of the process. Remember, this is not a substitute for a proper repair manual.
1. Safety First:
* Disconnect the battery's negative terminal. This prevents accidental shorts and electrical shocks.
* Wear safety glasses and gloves. Power steering fluid is messy and can irritate skin and eyes.
* Work in a well-ventilated area. Power steering fluid can have strong fumes.
2. Gather Tools and Supplies:
* Repair manual specific to your 2002 Chevy Cavalier. This is crucial.
* Socket wrench set (metric), including extensions and a ratchet.
* Wrench set (metric).
* Drain pan to catch power steering fluid.
* New power steering pump (ensure it's the correct one for your engine).
* New power steering fluid (the correct type for your vehicle).
* Shop rags or paper towels.
* Jack and jack stands (securely support the vehicle).
* Wheel chocks.
* Torque wrench (essential for proper tightening).
* Fluid pump (optional, but helpful for refilling the system).
3. Accessing the Power Steering Pump:
* Raise and secure the vehicle using jack stands. Always follow safe jacking procedures.
* Locate the power steering pump. It's usually near the front of the engine, often driven by a belt.
* Remove the serpentine belt. This usually involves loosening the tensioner pulley. Refer to your repair manual for the specific procedure – it varies by engine.
4. Removing the Old Power Steering Pump:
* Disconnect the power steering pressure hose. This often involves loosening a clamp and carefully removing the hose. Be prepared for fluid spillage. Have rags ready to absorb the fluid.
* Disconnect the power steering return hose. Same procedure as above.
* Disconnect the electrical connector (if applicable).
* Remove the pump mounting bolts. These are usually multiple bolts securing the pump to the engine block.
* Carefully remove the pump. It may be stubborn due to corrosion or sealant. Gentle persuasion (and possibly a pry bar – use cautiously!) may be needed.
5. Installing the New Power Steering Pump:
* Inspect the mounting surface on the engine block for any damage or debris. Clean it thoroughly.
* Install the new pump, aligning it with the mounting holes.
* Secure the pump with the mounting bolts, tightening them to the specified torque in your repair manual.
* Reconnect the power steering return hose.
* Reconnect the power steering pressure hose. Tighten hose clamps securely.
* Reconnect the electrical connector (if applicable).
* Reinstall the serpentine belt. Make sure it's properly routed around all the pulleys.
6. Refilling and Bleeding the System:
* Add new power steering fluid to the reservoir, checking the fluid level frequently. Use a funnel to avoid spills.
* Start the engine and let it run for a few minutes. Turn the steering wheel from lock to lock several times to circulate the fluid and remove air bubbles.
* Check the fluid level and add more fluid as needed.
* Inspect for leaks.
7. Final Checks:
* Check the fluid level again after driving the vehicle for a short distance.
* Listen for any unusual noises coming from the power steering system.
Important Considerations:
* Power steering fluid is corrosive. Clean up any spills immediately.
* Torque specifications are crucial. Use a torque wrench to avoid damaging the pump or engine.
* If you're uncomfortable with any part of this process, take your vehicle to a qualified mechanic. Improper repair can lead to serious damage.
This is a general overview. Again, always consult a repair manual specific to your 2002 Chevy Cavalier before attempting this repair. The specific steps and tools may vary slightly depending on your engine and vehicle configuration. Failing to follow the proper procedures could damage your car and possibly injure you.
