Here's a general outline. This is not a complete, step-by-step guide, and variations exist depending on the specific engine. Always consult a repair manual specific to your 1985 Chevy Celebrity wagon's engine (2.0L, 2.5L, or 2.8L V6 are possibilities) for precise instructions and torque specifications. Improper torque can damage the pump or other components.
Tools You'll Likely Need:
* Socket set (metric): Various sizes, including those for the pump mounting bolts, pulley bolts, and drain plug.
* Wrench set (metric): For various fittings and lines.
* Power steering fluid: The correct type for your vehicle.
* Drain pan: To catch old fluid.
* Pump pliers or line wrenches: For stubborn fittings.
* Torque wrench: Essential for proper tightening.
* New power steering pump: Ensure you get the correct replacement pump for your engine.
* Shop rags or paper towels: To clean up spills.
* Jack and jack stands: To safely support the vehicle.
* Wheel chocks: For added safety.
General Steps:
1. Preparation: Raise the front of the vehicle using a jack and secure it safely on jack stands. Engage the parking brake and use wheel chocks. Locate the power steering pump; it's usually near the front of the engine.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a drain pan.
3. Disconnect Components:
* Disconnect the power steering fluid lines: These are usually high-pressure lines, so be prepared for some fluid spillage even after draining the reservoir. Use line wrenches to loosen these connections. Plug the lines to prevent fluid loss.
* Disconnect the pulley: Remove the pulley bolt and carefully remove the pulley from the pump shaft.
* Disconnect the electrical connector: If present, disconnect any electrical connector to the pump.
4. Remove the Power Steering Pump: Remove the mounting bolts securing the pump to the engine block. The pump may be stubborn; use penetrating oil if necessary. Carefully remove the pump.
5. Installation:
* Install the new power steering pump: Make sure the new pump is oriented correctly.
* Reconnect the pulley: Install the pulley and tighten the bolt to the manufacturer's specified torque.
* Reconnect the power steering fluid lines: Tighten these connections to the manufacturer's specified torque.
* Reconnect the electrical connector (if applicable).
* Reinstall the mounting bolts: Tighten them to the manufacturer's specified torque.
6. Refill and Bleed the System:
* Refill the power steering fluid reservoir: Add the correct type and amount of power steering fluid.
* Bleed the system: This is crucial to remove air from the lines. The bleeding procedure may vary. Your repair manual will detail the process, often involving turning the steering wheel lock-to-lock with the engine running (while monitoring the fluid level).
7. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
8. Check Fluid Level: Check the fluid level in the reservoir and top it off as needed.
9. Test Drive: Take a short test drive to ensure the power steering is working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1985 Chevy Celebrity wagon is absolutely essential. This guide provides a general overview; the specific details and procedures may vary significantly.
* Safety: Always prioritize safety. Use jack stands properly, wear safety glasses, and be aware of hot engine components.
* Fluid Type: Use the correct type of power steering fluid recommended by Chevrolet for your vehicle.
* Torque Specifications: Always use a torque wrench and tighten bolts to the manufacturer's specified torque. Over-tightening can cause damage.
This task is best left to someone experienced with automotive repair if you're not comfortable working on your vehicle. If in doubt, consult a professional mechanic.
