Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Remove any engine covers obstructing access to the serpentine belt.
2. Use a serpentine belt tool or ratchet to release tension from the belt tensioner.
3. Remove the old serpentine belt and inspect pulleys for damage or wear.
4. Install the new serpentine belt following the routing diagram (usually found on a sticker in the engine bay).
5. Recheck the tension on the belt; it should be snug but not overly tight.

3. Check and Replace Worn Tires

Sub-steps:
1. Inspect all tires for uneven wear, cracks, or bulges.
2. Measure tread depth; replace tires that are below the manufacturer's recommended depth.
3. Install new tires if necessary, ensuring proper alignment and balancing.

4. Inspect and Service Brake System

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Check brake pads for wear; replace if they are below the minimum thickness.
3. Inspect calipers for proper operation; clean or replace if they appear to be sticking.
4. Reinstall the wheel and lower the vehicle.
