Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, wrench set, power steering fluid, and a funnel.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery if working on electrical components for safety.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level and fill it to the required level if low.
If the fluid is dirty or contaminated, proceed to flush the system.

3. Inspect for Leaks

Visually inspect power steering hoses and connections for any signs of leaks.
If leaks are found, replace the affected hoses or connections.
Clean any spilled fluid to prevent confusion during future inspections.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump from the hoses and electrical connectors.
Remove the pump from its mounting bracket.
Install the new power steering pump and connect hoses and electrical connectors securely.
Reinstall the serpentine belt, ensuring all pulleys are aligned.

5. Bleed the Power Steering System

Fill the power steering reservoir with fresh fluid.
Start the engine and turn the steering wheel fully left and right several times to bleed air from the system.
Check fluid levels again and top off if necessary.
