Tools You'll Likely Need:
* Socket set (metric): Various sizes, including likely a 15mm, 13mm, and potentially others depending on your specific pump and brackets.
* Wrench set (metric): For assisting with socket work and potentially some line fittings.
* Wrenches (possibly specialized): Line wrenches are ideal for loosening and tightening power steering lines to avoid damaging them.
* Drain pan: To catch power steering fluid.
* Shop rags or absorbent towels: To clean up spilled fluid.
* Power steering fluid: To refill the system after the repair. Use the correct type specified in your owner's manual.
* Pry bar (plastic or wood preferred): To help break free stubborn connections.
* Ratchet and extensions: To reach difficult bolts.
* Torque wrench: Crucial for tightening bolts to the proper specification to avoid leaks and damage.
Steps (General Outline - Consult your repair manual for specifics):
1. Disconnect the Battery: This is crucial to prevent accidental short circuits.
2. Drain the Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into your drain pan.
3. Remove the serpentine belt: This usually involves loosening the tensioner pulley. Consult your repair manual for the correct procedure – this step is *essential* before removing the pump.
4. Disconnect the Power Steering Lines: There will be at least two lines – high-pressure (usually smaller diameter, often with a banjo bolt connection) and low-pressure (usually larger diameter). Use line wrenches to loosen these connections carefully to avoid damaging the lines or fittings. Have rags ready to catch any remaining fluid.
5. Disconnect Electrical Connections (if any): Some power steering pumps may have a sensor or other electrical connector. Disconnect this carefully.
6. Remove the Pump Mounting Bolts: These bolts secure the pump to the engine block or bracket. The number and location of these bolts will vary depending on the specific engine and pump. Use the appropriate sockets and wrenches.
7. Remove the Power Steering Pump: Once all bolts are removed, the pump should be free. It might be a bit stubborn due to corrosion, so gently pry it loose if necessary, using plastic or wood to avoid damage.
8. Inspect the Pump and its Surroundings: Examine the pump for any signs of damage or leaks. Check the pulley for any wear or damage. Also, inspect the mounting surface on the engine for any damage or corrosion.
9. Install the New Pump: Reverse the removal procedure to install the new pump. Be sure to use new gaskets and seals if provided with the replacement pump.
10. Reconnect the Power Steering Lines: Tighten the lines carefully to the proper torque specification (found in your repair manual).
11. Reconnect the Electrical Connector (if any):
12. Reinstall the Serpentine Belt: Ensure it's properly routed around all pulleys.
13. Reconnect the Battery:
14. Refill the Power Steering Fluid Reservoir: Add the correct type and amount of power steering fluid as specified in your owner's manual.
15. Bleed the System (if necessary): Some repairs may require bleeding the power steering system to remove air bubbles. Your repair manual will specify if this is required.
Important Considerations:
* Repair Manual: This is the single most important tool. It provides detailed, vehicle-specific instructions and torque specifications.
* Safety First: Wear safety glasses and gloves to protect yourself from potential hazards.
* Fluid Disposal: Dispose of the old power steering fluid properly according to your local regulations.
This is a complex procedure. If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Incorrect installation can lead to serious problems, including damage to your power steering system and even engine damage.
