Solution

1. Preparation

Tools Required:
- Wrench set
- Screwdriver set
- OBD-II scanner
- Fluid catch basin
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Wear safety gloves and goggles for protection.

2. Fluid Level Adjustment

Check the power steering fluid level; if low, top it off using the recommended fluid type (Toyota PS Fluids).
If the fluid is contaminated (dark or has debris), proceed to drain and replace it.

3. Addressing Leaks

Hoses and Fittings:
- Inspect all power steering hoses for cracks or loose connections. Tighten or replace as necessary.
Pump Replacement:
- If the pump is leaking, remove it:
  1. Disconnect the negative battery terminal.
  2. Remove the serpentine belt from the power steering pump.
  3. Disconnect fluid lines using a wrench.
  4. Remove mounting bolts and take out the pump.
  5. Install the new pump and reverse the removal steps.

4. Inspect and Replace Belts

If the serpentine belt shows signs of wear:
1. Release tension from the belt using a wrench.
2. Remove the old belt and replace it with a new one.
3. Ensure proper tension and alignment before securing.

5. Final Checks

Reconnect the battery terminal.
Start the engine and turn the steering wheel from side to side to bleed air from the system.
Check for leaks around the pump and hoses.
