Here's a general overview of the steps involved. This is not a comprehensive guide and should not be used as a sole source for performing this repair. Improperly completing this repair could lead to injury or further damage to your vehicle.
Tools You'll Likely Need:
* Wrench set (metric): Various sizes, including sockets, ratchets, and extensions.
* Torque wrench: Essential for tightening bolts to the correct specification.
* Power steering fluid: The correct type for your Windstar.
* Drain pan: To catch the old power steering fluid.
* New power steering pump: Make sure you get the correct one for your vehicle.
* Gloves: To protect your hands from fluid and grime.
* Jack and jack stands: To safely lift the vehicle.
* Possibly a pry bar: To help separate components.
* New power steering belt (highly recommended): Since you're already in there, replacing the belt minimizes the risk of future issues.
General Steps (Again, consult your repair manual):
1. Safety First: Disconnect the negative battery cable. Support the vehicle securely with jack stands.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and drain the fluid into a pan.
3. Access the Pump: This often involves removing some components like the serpentine belt, belt tensioner, and possibly other accessories to get to the power steering pump. The exact components will vary by year and engine. Your repair manual will detail this.
4. Disconnect Components: Disconnect the power steering pressure lines (usually high and low pressure). Be prepared for some fluid spillage. Have rags ready. You may need a line wrench to loosen the fittings. Note the orientation of the lines before disconnecting.
5. Remove the Pump: Remove the mounting bolts holding the power steering pump to the engine block. This may require some maneuvering and might be difficult due to limited space.
6. Install the New Pump: Install the new power steering pump, ensuring it's properly seated. Tighten the mounting bolts to the torque specifications in your repair manual.
7. Reconnect Components: Reconnect the power steering pressure lines, ensuring they are securely fastened and tightened to the proper specifications.
8. Reinstall Belt and Tensioner: Reinstall the serpentine belt and tensioner.
9. Add Power Steering Fluid: Fill the power steering fluid reservoir with the correct type and amount of fluid.
10. Bleed the System: Start the engine and turn the steering wheel lock-to-lock several times to bleed the air out of the system. Check the fluid level and add more as needed.
11. Inspect for Leaks: Inspect for any leaks around the pump and lines.
12. Road Test: Test drive the vehicle to ensure proper power steering operation.
Important Considerations:
* Fluid Type: Use the correct type of power steering fluid recommended for your Windstar.
* Torque Specifications: Use a torque wrench to tighten all bolts to the manufacturer's specifications. Over-tightening can damage components.
* Alignment: Make sure the new pump is properly aligned before tightening the bolts.
* Professional Help: If you're not comfortable performing this repair, take your Windstar to a qualified mechanic.
This is a general outline. Always refer to a repair manual specific to your vehicle for detailed instructions and torque specifications. Failure to do so could result in damage to your vehicle or personal injury.
