Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Using a turkey baster or siphon, extract old fluid and replace with new, manufacturer-recommended power steering fluid.
Recheck the fluid level and cap securely.

3. Inspect and Replace Serpentine Belt

Locate the serpentine belt tensioner and use a socket to relieve tension.
Remove the old serpentine belt from the pulleys.
Compare the old belt with the new one to ensure correct size.
Install the new serpentine belt following the routing diagram located on the engine bay.
Reapply tension to the belt and ensure it is seated properly on all pulleys.

4. Check Power Steering System

Inspect all power steering hoses for leaks or cracks; replace if necessary.
If noise persists after fluid replacement and belt inspection, consider replacing the power steering pump.
To replace the pump, remove any accessories blocking access, disconnect the inlet and outlet hoses, remove mounting bolts, and install the new pump in reverse order.
