Changing the power steering pump is a moderately difficult job, requiring some mechanical aptitude and the right tools. It's not a simple "bolt-on/bolt-off" situation. Here's a general outline of the process, but I strongly recommend consulting a repair manual specific to your 2002 Saturn Vue's engine. This manual will provide precise details, torque specifications, and diagrams vital for success. Incorrect procedures can lead to damage.
General Steps (Consult your repair manual for precise details and torque specs):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental shorts and electrical damage. Let the engine cool completely before starting.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir. Carefully drain the fluid into a suitable container.
3. Remove Belts: You'll need to remove the serpentine belt (or belts, depending on your engine) that drives the power steering pump. Use the appropriate tools to loosen and remove the belt tensioner.
4. Disconnect Fluid Lines: Carefully disconnect the high-pressure and low-pressure power steering fluid lines from the pump. Have rags ready to absorb any spilled fluid. Be aware that the high-pressure line will contain pressurized fluid. You may need to relieve the pressure before disconnecting. Some use a special tool to accomplish this.
5. Remove the Pump: The pump is usually held in place by several bolts. Locate and carefully remove these bolts. The pump might be a little stubborn due to corrosion; penetrating oil can help.
6. Install the New Pump: Install the new power steering pump, ensuring it's correctly aligned. Tighten the bolts to the manufacturer's specified torque (found in your repair manual).
7. Reconnect Fluid Lines: Reconnect the high and low-pressure lines, ensuring they are securely attached.
8. Reinstall Belts: Reinstall the serpentine belt(s), ensuring proper routing and tension. Use a belt tension gauge if available.
9. Fill Power Steering Fluid: Add new power steering fluid to the reservoir. Consult your owner's manual for the correct type of fluid.
10. Bleed the System: You may need to bleed the air out of the power steering system. This often involves turning the steering wheel lock-to-lock several times while the engine is running. Again, your repair manual will guide you here.
11. Check for Leaks: After everything is reassembled, carefully check for any leaks around the pump and fluid lines.
12. Reconnect Battery: Reconnect the negative battery terminal.
Tools You Will Likely Need:
* Wrench set (metric)
* Socket set (metric)
* Ratchet
* Torque wrench
* Screwdrivers
* Belt tensioner tool (often specific to the vehicle)
* Drain pan
* New power steering fluid
* Penetrating oil
* Rags
* Safety glasses
* Gloves
Important Considerations:
* Proper fluid disposal: Power steering fluid is harmful to the environment. Dispose of it properly at an auto parts store or recycling center.
* Torque specifications: Using the correct torque is essential to prevent damage.
* Repair manual: A repair manual specific to your 2002 Saturn Vue is invaluable.
This is a complex procedure. If you're not comfortable working on your car, it's best to take it to a qualified mechanic. Attempting this without the proper knowledge and tools could lead to further damage or injury.
