Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Serpentine Belt

Remove the engine cover (if applicable) using a socket set.
Locate the serpentine belt tensioner and release tension using a wrench.
Remove the belt from the pulleys.
Inspect the old belt for cracks or fraying; replace if necessary.
Install the new serpentine belt following the routing diagram located near the engine bay.
Reapply tension with the tensioner, ensuring the belt is properly seated on all pulleys.

3. Check Fluid Levels

Locate the power steering reservoir and check the fluid level; add fluid if low.
Check the transmission fluid by removing the dipstick, inspecting the color and smell, and adding the appropriate fluid if necessary.

4. Inspect Alternator and Power Steering Pump

Use a multimeter to check the alternator output while the engine is running (should be around 13.8 to 14.4 volts).
Listen for any unusual noises from the alternator or power steering pump while the engine is idling.
Replace the alternator or power steering pump if any excessive noise or operational issues are detected.
