Solution

1. Preparation

Gather tools: OBD-II scanner, fluid catch pan, socket set, torque wrench, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level; add manufacturer-recommended power steering fluid if low.
Check the fluid condition; if dark or contaminated, proceed to flush the system.

3. Inspect and Replace Leaking Components

If leaks are present, identify the source (hoses, pump, or rack).
Use the socket set to remove the damaged hoses or pump.
Replace with new OEM or equivalent parts. Torque connections to manufacturer specifications.

4. Inspect the Serpentine Belt

Visually inspect the serpentine belt for any signs of wear, fraying, or cracks.
If damaged, remove the belt using a wrench to release tension and replace it with a new belt.

5. Test Power Steering Pump

Connect a pressure gauge to the power steering pump outlet.
Start the engine and turn the steering wheel to check for appropriate pressure readings.
If the pump is faulty, remove it using the socket set and replace it with a new unit.

6. Final Assembly

Reinstall any removed components in reverse order.
Ensure all connections are secure and fluid levels are topped off.
Reattach the power steering fluid reservoir cap.
