Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, mechanic's gloves, safety glasses
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is cool before beginning inspections to avoid burns.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (usually found on the engine cover).
2. Use a socket set to relieve tension on the serpentine belt tensioner and remove the belt.
3. Inspect the belt for cracks, frays, or signs of glazing. Replace if damaged.
4. Install the new serpentine belt, ensuring it follows the routing diagram correctly.
5. Recheck the tensioner to ensure proper tension is applied.

3. Inspect and Replace Worn Brake Components

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for excessive wear or overheating. Replace if necessary.
4. Check the brake caliper for proper operation, ensuring it isn't stuck.
5. Reassemble the wheel and lower the vehicle.

4. Inspect for Fluid Leaks

Sub-steps:
1. Check under the vehicle for any pooling fluids that may indicate leaks.
2. Inspect hoses and connections for signs of wear or damage.
3. Repair or replace any damaged hoses or seals to prevent leaks.
4. Clean any residue from the engine or undercarriage to monitor for further leaks.
