Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, fluid check tools, and a flashlight.
Ensure the vehicle is parked on a level surface with the engine off.

2. Inspect Power Steering System

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check fluid level; add the appropriate type of power steering fluid if low.
3. Inspect hoses and connections for leaks or wear.
4. If leaks are found, replace the affected hoses or fittings.

3. Check Serpentine Belt

Sub-steps:
1. Locate the serpentine belt and visually inspect it for cracks, frays, or glazing.
2. If damage is found, use a socket set to release tension on the belt and remove it.
3. Install a new serpentine belt, ensuring proper routing according to the diagram.

4. Examine Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if equipped).
2. Remove the dipstick, clean it, and reinsert to check fluid level.
3. If low, add the manufacturer's recommended transmission fluid.
4. If fluid is dark or has a burnt smell, consider a transmission fluid change.
