Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid catch pan, and flashlight.
Park the vehicle on a level surface and engage the parking brake.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with manufacturer-recommended power steering fluid.

3. Inspect for Leaks

Use a flashlight to inspect hoses and connections for signs of leakage.
If a leak is found, replace the damaged hose or seal.

4. Examine the Power Steering Pump

Disconnect the negative battery terminal to avoid electrical shorts.
Remove the power steering pump by loosening the mounting bolts using a socket set.
Inspect the pump for noise or damage; if defective, replace the pump.

5. Inspect the Serpentine Belt

Check the serpentine belt for cracks, fraying, or signs of wear.
If the belt is worn, replace it with a new belt, ensuring proper tension is set according to manufacturer specifications.

6. Test Drive and Final Checks

Reconnect the battery terminal and take the vehicle for a short test drive.
Monitor for any residual noises while turning and ensure fluid levels are stable.
