Solution

1. Preparation

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

2. Inspect Power Steering System

Fluid Level Check:
- Locate the power steering reservoir.
- Remove the cap and check fluid level; add fluid if low.
Leak Inspection:
- Visually inspect hoses and fittings for leaks.
- If leaks are present, replace damaged hoses using a socket set.

3. Examine Serpentine Belt

Belt Condition:
- Inspect the serpentine belt for cracks or fraying.
- If damaged, remove the belt using a socket set and replace it with a new belt.
Belt Tension:
- Check the tensioner for proper tension; replace if malfunctioning.

4. Transmission Fluid Check

Fluid Level:
- Locate the transmission dipstick and check fluid level.
- If low, add the appropriate transmission fluid as per manufacturer's specifications.
Fluid Condition:
- Inspect fluid color and smell; if burnt or dark, consider a fluid change.
