Solution

1. Preparation

Gather tools: socket set, screwdrivers, OBD-II scanner, and flashlight.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Belts

Inspect the serpentine belt:
- Remove any covers obstructing access to the belt.
- Check for cracks, fraying, or signs of melting.
- If damage is found, proceed to replace the belt.
Replace the serpentine belt:
- Loosen the tensioner using a socket wrench.
- Remove the old belt and route the new belt following the belt routing diagram.
- Reapply tension and ensure it is secure.

3. Brake Inspection and Replacement

Inspect brake components:
- Remove the wheel to access brake components.
- Check brake pads for wear and rotors for overheating discoloration.
Replace worn brake pads or rotors:
- If worn, remove the caliper and bracket using a socket set.
- Replace the brake pads or rotors as necessary.
- Reinstall the caliper and ensure it is torqued to manufacturer specifications.

4. Address Fluid Issues

Check and top off or replace fluids:
- Inspect engine oil, coolant, and transmission fluid levels.
- If fluids are low or contaminated, drain and replace with manufacturer-recommended fluids.

5. Final Assembly and Cleanup

Reassemble any components that were removed for inspection.
Reconnect the battery and ensure all tools and debris are cleared from the work area.
