Before you begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shorts. Wear safety glasses and gloves.
* Gather Tools: You'll need a variety of tools, including:
* Socket wrench set (metric)
* Wrenches (metric)
* Drain pan
* Fluid catch container
* New power steering pump (ensure it's the correct one for your engine)
* New power steering fluid (specified for your vehicle)
* Torque wrench
* Pliers
* Rags or shop towels
* Consult a Repair Manual: A Haynes or Chilton manual specific to your 1995 Chevy Cavalier is highly recommended. It will provide detailed diagrams and torque specifications crucial for success.
Steps (General Outline - Refer to your repair manual for specifics):
1. Drain the Power Steering Fluid: Locate the power steering fluid reservoir. Carefully drain the fluid into your drain pan. This minimizes fluid spillage during the pump replacement.
2. Access the Power Steering Pump: This usually involves removing various components to gain access. This might include:
* Removing the serpentine belt (using a belt tensioner tool, if necessary).
* Removing the pulley from the power steering pump (may require a puller).
* Removing any brackets or hoses obstructing access to the pump mounting bolts.
3. Disconnect Hoses and Lines: Carefully disconnect the high-pressure and low-pressure power steering lines from the pump. Have your fluid catch container ready to minimize fluid loss. Mark the hoses or take pictures to ensure correct reinstallation. Some lines may use clamps that require special tools for removal.
4. Remove the Power Steering Pump: Once the hoses and lines are disconnected, remove the bolts securing the pump to the engine block. The pump might be a little stubborn due to corrosion; use penetrating oil if necessary. Support the pump as you remove the last bolt to avoid dropping it.
5. Install the New Power Steering Pump: Carefully install the new power steering pump, ensuring it's properly seated and aligned. Replace the mounting bolts and tighten them to the manufacturer's specified torque (found in your repair manual).
6. Reconnect Hoses and Lines: Carefully reconnect the power steering hoses and lines, ensuring a tight seal. Double-check your markings or photos to ensure correct routing.
7. Reinstall Pulley and Belt: Reinstall the pulley (if removed) and the serpentine belt, making sure the belt is properly tensioned (consult your repair manual for proper tension).
8. Refill the Power Steering Fluid Reservoir: Add the specified power steering fluid to the reservoir. Check your repair manual for the correct fluid type and amount.
9. Bleed the System (if necessary): Some power steering systems may require bleeding after a pump replacement. Your repair manual will describe this procedure, which usually involves turning the steering wheel lock-to-lock while the engine runs.
10. Test the System: Start the engine and check for leaks. Turn the steering wheel from lock to lock several times, listening for any unusual noises. Check the power steering fluid level and top off as needed.
Important Considerations:
* Fluid Type: Use the correct type of power steering fluid recommended for your vehicle. Using the wrong fluid can damage the pump and other components.
* Torque Specifications: Always use a torque wrench and follow the manufacturer's torque specifications for all bolts. Over-tightening can cause damage.
* Leaks: Carefully inspect all connections for leaks after refilling the fluid.
