Solution

1. Preparation

Gather tools and materials: OBD-II scanner, torque wrench, socket set, coolant, and replacement belts or hoses as needed.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Damaged Components

Inspect Belts and Hoses:
- Carefully examine all belts for fraying or cracking.
- Check hoses for leaks, cracks, or signs of wear.
- If any damage is found, proceed to replace the affected belt or hose.
Replacement Procedure:
- For belts, loosen the tensioner using the appropriate socket.
- Remove the damaged belt and install the new one, ensuring it aligns correctly with all pulleys.
- For hoses, use pliers to remove the clamps and take off the damaged hose. Install the new hose with new clamps.

3. Coolant System Inspection

Inspect the coolant reservoir and radiator for leaks.
If coolant is low, refill with the manufacturer-recommended coolant type.
If leaks are found, replace the radiator or hoses as necessary.

4. Brake Inspection

Inspect the brake pads and rotors for excessive wear or damage.
If pads are worn down to the backing or rotors are scored, replace them.

5. Clean and Clear Engine Bay

Remove any debris or foreign objects that may have fallen into the engine bay.
Clean any spilled fluids or materials that could contribute to odors or damage.
