Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool
Remove the belt by loosening the tensioner using the tensioner tool.
Inspect the belt for cracks, fraying, or glazing.
If damaged, replace with a new serpentine belt, ensuring it is routed correctly as per the vehicle's service manual.

3. Inspect and Replace Brake Components (if applicable)

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner
Raise the vehicle using a jack and secure it with jack stands.
Remove the front or rear wheels as necessary.
Inspect brake pads for thickness; replace if worn below 3mm.
Check brake rotors for scoring or warping; machine or replace if necessary.
Reassemble the wheels and lower the vehicle.

4. Check Pulley and Tensioner

Tools Required: Socket set, torque wrench
Visually inspect the tensioner for any signs of wear or failure.
Replace the tensioner if it does not maintain proper tension on the belt.
Ensure that all pulleys rotate freely and are not misaligned.
