Solution

1. Preparation

Tools Required: Safety glasses, gloves, flashlight, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is turned off. Allow the engine to cool down before beginning inspection.

2. Inspect and Replace the Serpentine Belt

Sub-steps:
1. Open the engine compartment and locate the serpentine belt.
2. Visually inspect the belt for signs of damage such as cracks, fraying, or glazing.
3. If damaged, remove the tensioner bolt using a socket wrench and carefully release tension on the belt.
4. Remove the old belt and install the new belt by routing it according to the belt routing diagram usually located on a sticker in the engine bay.
5. Reapply tension by tightening the tensioner bolt to the manufacturer's specifications.

3. Check for Fluid Leaks

Sub-steps:
1. Inspect under the vehicle for any fluid leaks, especially oil or coolant.
2. If any leaks are found, identify the source and replace damaged gaskets or seals as necessary.
3. Clean any spilled fluids from the engine or exhaust components to prevent burning smells.

4. Examine Tires and Alignment

Sub-steps:
1. Inspect each tire for uneven wear or damage.
2. If any issues are detected, consider rotating or replacing the tires.
3. If alignment is suspected, take the vehicle to a professional for a wheel alignment check.
