Tools Required: Socket set, belt tensioner tool
Sub-steps:
1. Remove the engine cover (if applicable) to access the serpentine belt.
2. Use the belt tensioner tool to relieve tension and remove the belt from the pulleys.
3. Inspect the old belt for cracks, fraying, or glazing.
4. Install the new serpentine belt, ensuring it follows the correct routing diagram found on the engine bay.
5. Reapply tension using the belt tensioner and check for proper alignment.

3. Inspect Tires

Tools Required: Tire pressure gauge, jack, jack stands
Sub-steps:
1. Check tire pressure and ensure it is within manufacturer specifications.
2. Inspect tires for signs of uneven wear or damage.
3. If necessary, rotate or replace tires that show excessive wear or damage.
4. Re-inflate tires to the recommended pressure.

4. Brake System Inspection

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheels to access the brake components.
