Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the recommended fluid type.
If the fluid is dirty or has particles, drain the old fluid and replace it.
- Tools Required: Fluid pump, funnel
- Safety Warning: Avoid contact with skin, as fluid can cause irritation.

3. Inspect and Replace Serpentine Belt

Visually inspect the serpentine belt for cracks or wear.
If damaged, release tension using a belt tensioner tool.
Remove the old belt and install a new belt according to the routing diagram located in the engine bay.
- Tools Required: Belt tensioner tool, socket set
- Torque Values: Ensure the belt is tight but not overly strained.

4. Inspect and Replace Power Steering Pump (if necessary)

Disconnect the inlet and outlet hoses from the power steering pump.
Remove the mounting bolts and lift out the old pump.
Install the new pump and connect the hoses securely.
- Tools Required: Wrench set, socket set
- Safety Warning: Ensure no fluid spills on the engine components.
