Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety, especially if working on electrical components.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Visually inspect serpentine and timing belts for cracks, fraying, or signs of wear.
3. If damage is found, loosen the tensioner and remove the affected belt.
4. Install the new belt by routing it according to the manufacturer's diagram.
5. Tighten the tensioner to the specified torque (usually around 15-25 ft-lbs).

3. Address Fluid Leaks

Sub-steps:
1. Locate any fluid leaks identified during the diagnostic steps.
2. If oil or coolant is found leaking, replace damaged seals or gaskets as necessary.
3. Clean any fluid stains from components using a degreaser and rag.
4. Refill any low fluids to the appropriate levels.

4. Brake Inspection and Replacement

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads and rotors for excessive wear or glazing.
4. If brake pads are worn, replace them with new pads, ensuring proper alignment.
5. Reinstall the wheel and lower the vehicle.

5. Tire Inspection and Replacement

Sub-steps:
1. Check tire tread depth and look for any embedded objects or deformities.
2. If tires are worn unevenly, rotate or replace them as necessary.
3. Ensure proper tire pressure is maintained according to the manufacturer’s specifications.
