Solution

1. Preparation

Tools Required: Safety glasses, gloves, jack and jack stands, socket set, OBD-II scanner.
Engage the parking brake and ensure the vehicle is on a flat surface. Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Inspect and Replace Damaged Belts

Inspect Belts: Check all serpentine belts for cracks, fraying, or signs of wear. If any damage is found, proceed to replace.
Remove Old Belt: Loosen the tensioner pulley using a socket wrench, then remove the old belt from all pulleys.
Install New Belt: Route the new belt according to the belt routing diagram usually found on a sticker in the engine bay. Ensure it is positioned correctly on all pulleys.
Re-tension the Belt: Use the tensioner to apply tension to the new belt and ensure it is tight but not over-tensioned.

3. Address Fluid Leaks

Identify Source of Leak: Clean any spilled fluids and use a dye or UV light to trace any leaks.
Replace Seals or Gaskets: If leaks are found from gaskets or seals, replace them with new components. Use manufacturer-recommended sealant if required.
Refill Fluids: After addressing the leaks, refill any necessary fluids to their proper levels.

4. Brake Inspection and Replacement

Inspect Brakes: Check brake pads and rotors for excessive wear. Look for signs of overheating, such as blue discoloration.
Replace Pads and Rotors: If worn, remove the wheel, unbolt the caliper, and replace the pads and/or rotors as necessary, ensuring proper torque specifications are followed.
Bleed Brake System: If brake fluid was lost, bleed the system to remove any air.

5. Final Checks

Reconnect Battery: After all repairs, reconnect the battery.
Start Vehicle: Run the engine and monitor for any unusual smells or noises, checking that the issue has been resolved.
