Solution

1. Preparation

Gather tools: socket set, wrench set, fluid catch pan, and a funnel.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues and ensure safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level using the dipstick or markings on the reservoir.
If low, use the appropriate power steering fluid (check owner’s manual for specifications).
Add fluid until it reaches the proper level.

3. Inspect and Repair Leaks

Visually inspect all power steering hoses for cracks or damage.
If leaks are found, replace the damaged hoses.
- Sub-steps:
  - Use the socket/wrench to loosen hose clamps.
  - Detach the hose and clean the area.
  - Install the new hose and secure it with clamps, ensuring a tight fit.

4. Replace Power Steering Pump (if necessary)

If the pump is faulty, replace it:
- Sub-steps:
  - Remove the serpentine belt by loosening the tensioner.
  - Unbolt the power steering pump from its mounting bracket.
  - Disconnect the fluid lines (be prepared for fluid spillage).
  - Install the new pump and reconnect all lines.
  - Reattach the serpentine belt, ensuring proper alignment.

5. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock several times to remove air bubbles.
Check the fluid level again, topping off if necessary.
