Safety First!
* Disconnect the negative battery terminal before starting any work on the vehicle's electrical system.
* Wear safety glasses to protect your eyes from flying debris.
* Use jack stands to safely support the vehicle after raising it. Never work under a vehicle supported only by a jack.
* Dispose of fluids properly. Power steering fluid is harmful to the environment.
Tools You'll Likely Need:
* Jack and jack stands
* Wrench set (metric)
* Socket set (metric)
* Ratchet
* Power steering fluid catch pan
* Pliers
* Screwdrivers (Phillips and flathead)
* Torque wrench (recommended)
* Shop rags or paper towels
Procedure (General Steps):
1. Drain the power steering fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a catch pan. You might need to loosen a drain plug or siphon the fluid out.
2. Remove the serpentine belt: Use a belt wrench or other appropriate tool to loosen the tensioner pulley, allowing you to remove the serpentine belt. Consult your repair manual for the correct procedure; this step's specifics vary greatly depending on the year and engine. Note the belt routing to ensure correct reinstallation.
3. Disconnect the power steering lines: Locate the high-pressure and low-pressure power steering lines connected to the pump. Carefully loosen the lines using the correct size wrench. Have a rag ready to catch any remaining fluid. Some lines may require special tools or a flare nut wrench to avoid damaging the fittings.
4. Remove the pump mounting bolts: The power steering pump is usually bolted to the engine block. Locate the bolts and carefully remove them using the appropriate size socket and ratchet. You may need to use extensions or a swivel socket to reach some bolts.
5. Remove the pump: Once all the bolts are removed, carefully remove the power steering pump. It may be slightly stiff due to the pump's internal components or corrosion. Gently wiggle it free.
6. Inspect the pump and seals (Optional): If you're replacing the pump, this is a good time to inspect the old pump for any obvious signs of failure.
7. Install the new pump (if applicable): Reverse the removal procedure to install a new pump. Ensure that all the connections are secure, especially the power steering lines. Tighten the bolts to the manufacturer's specified torque (consult your repair manual).
8. Refill the power steering fluid reservoir: After installing the new pump and reconnecting all lines, refill the power steering fluid reservoir to the correct level.
9. Reinstall the serpentine belt: Reinstall the serpentine belt following the correct routing. Make sure it's seated correctly around all the pulleys.
10. Check for leaks: Start the engine and check for any leaks around the power steering pump and lines. Run the engine for a short time, then check the fluid level.
11. Reconnect the battery: Reconnect the negative battery terminal.
Important Considerations:
* Repair Manual: A repair manual specific to your 1994 Chevy Corsica is crucial. It will provide detailed diagrams, torque specifications, and specific procedures.
* Difficulty: This is not a beginner's job. If you're not comfortable working on your car, it's best to take it to a qualified mechanic.
* Fluid Type: Use the correct type of power steering fluid specified for your vehicle.
Remember this is a general guide. Always refer to your vehicle's repair manual for detailed, accurate instructions. Improperly performing this repair can damage your vehicle.
