Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid containers, and a flashlight.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt and inspect for wear or damage.
2. If damaged, release tension on the tensioner using a wrench and remove the old belt.
3. Compare the new belt with the old one to ensure proper size and fit.
4. Install the new belt following the routing diagram on the engine bay.
5. Reapply tension using the tensioner and ensure the belt is seated correctly on all pulleys.

3. Check Power Steering System

Sub-steps:
1. Locate the power steering fluid reservoir and check the fluid level.
2. If low, top off with the recommended power steering fluid.
3. Inspect the power steering pump for leaks or damage.
4. If noise persists, consider replacing the power steering pump.

4. Inspect Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level and condition.
2. If low, add the appropriate transmission fluid.
3. If fluid appears burnt or contains debris, consider a transmission fluid change.
