Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Open the hood and locate the serpentine belt routing diagram.
2. Loosen the tensioner pulley using a socket wrench to relieve tension on the belt.
3. Remove the old serpentine belt and check for signs of cracking or fraying.
4. Install the new serpentine belt, following the routing diagram.
5. Reapply tension using the tensioner pulley and ensure it is secure.

3. Check and Replace Worn Tires

Sub-steps:
1. Inspect each tire for uneven wear, bulges, or damage.
2. Measure tread depth; replace tires if tread is below 2/32 of an inch.
3. If necessary, replace with new tires of the same size and type.
4. Align the wheels if misalignment is detected.

4. Brake System Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access brake components.
3. Inspect brake pads for wear and replace if they are less than 1/8 inch thick.
4. Check for caliper operation and ensure it is not sticking.
5. Reassemble the wheel and lower the vehicle.

5. Address Leaks and Fluid Contact

Sub-steps:
1. Inspect the engine for any oil, coolant, or transmission fluid leaks.
2. Clean any spilled fluids with appropriate degreasers.
3. Secure or replace leaking gaskets or seals as needed.
