Safety First:
* Disconnect the negative battery terminal. This prevents accidental short circuits.
* Wear safety glasses to protect your eyes from fluid splashes.
* Work in a well-ventilated area. Power steering fluid is harmful if ingested or inhaled.
* Have absorbent material ready to catch any spilled fluid.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Wrenches (metric)
* Drain pan
* Shop rags or paper towels
* Possibly a pry bar (for stubborn fittings)
Procedure:
1. Drain the power steering fluid: Locate the power steering fluid reservoir. Remove the cap and carefully drain the fluid into a drain pan.
2. Remove the serpentine belt: Consult your repair manual for the correct routing of the serpentine belt. Use a belt tensioner tool (often a special socket or wrench) to release tension on the belt so you can remove it. If you don't have a tensioner tool, you might be able to carefully loosen the tension by turning the tensioner pulley. Note the routing of the belt carefully for reinstallation.
3. Disconnect the pressure hose: This hose connects to the pump outlet. Loosen the clamp holding the hose to the pump and carefully disconnect the hose. Be prepared for some fluid leakage.
4. Disconnect the return hose: This hose connects to the pump inlet. Loosen the clamp and disconnect the hose. Again, be prepared for some fluid leakage.
5. Remove the power steering pump mounting bolts: These are typically located on the pump's mounting bracket. Use the appropriate size socket and ratchet to remove the bolts. You may need extensions depending on access.
6. Remove the pump: Once the bolts are removed, the pump should come free. It might be stuck due to corrosion or sealant. If necessary, gently pry it loose with a pry bar, using caution to avoid damaging the pump or surrounding components.
7. Clean the mounting surface: Remove any debris or old sealant from the engine block and the pump mounting bracket.
Reinstallation:
Reinstallation is the reverse of the removal process. Remember to:
* Use new gaskets or seals as needed.
* Tighten the bolts to the correct torque specifications (consult your repair manual).
* Refill the power steering fluid reservoir to the correct level.
* Check for leaks.
* Reinstall the serpentine belt, ensuring it's properly routed.
Important Notes:
* Fluid Type: Use the correct type of power steering fluid specified in your owner's manual.
* Bleeding the System: After reinstallation, you may need to bleed the power steering system to remove any air bubbles. This often involves turning the steering wheel lock-to-lock several times with the engine running. Again, consult your repair manual for the correct bleeding procedure.
This is a complex procedure. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Attempting this repair without proper knowledge and tools could lead to damage or injury. Always refer to a repair manual specific to your 1993 Chevrolet Cavalier 2.2L for accurate and detailed instructions.
