Solution

1. Preparation

Gather tools and parts.
Ensure vehicle is parked on a level surface and engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level.
3. If fluid is low, add the recommended power steering fluid type (typically Dexron III or CHF 202).
4. If fluid is contaminated (dark or has debris), proceed to flush the system.

3. Check and Repair Leaks

Sub-steps:
1. Visually inspect the power steering hoses and pump for signs of leaks.
2. If leaks are found, replace the affected hoses or seals.
3. Tighten any loose connections and ensure the pump is securely mounted.

4. Inspect and Replace Power Steering Pump

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Remove the serpentine belt from the power steering pump.
3. Unbolt the power steering pump from its mounting bracket.
4. Disconnect the fluid lines and remove the pump.
5. Install the new pump and reconnect the fluid lines, ensuring no cross-threading occurs.
6. Bolt the pump back onto the bracket and reinstall the serpentine belt.

5. Final Steps

Reconnect the battery.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check fluid levels again and top off if necessary.
