Disconnect the battery before working on electrical components.

2. Inspect and Replace Damaged Belts

Sub-steps:
- Remove the engine cover if applicable using a socket set.
- Visually inspect the serpentine belt and any other belts for cracks or fraying.
- If damaged, remove the old belt by releasing tension using a wrench on the tensioner pulley.
- Install a new belt, ensuring it follows the correct routing and tension specifications.

3. Check and Replace Worn Hoses

Sub-steps:
- Inspect all rubber hoses in the engine bay for signs of wear or melting.
- Disconnect any damaged hoses using pliers and replace them with new ones, ensuring proper fitment and securing clamps tightly.

4. Address Brake Issues

Sub-steps:
- Inspect brake pads and rotors for excessive wear or glazing.
- If necessary, remove the wheel using a socket set, then remove the brake caliper and pads for inspection.
- Replace worn brake pads and ensure rotors are not warped or damaged.

5. Clean and Repair Oil Leaks

Sub-steps:
- Locate any oil leaks by checking the oil pan, valve cover, and other seals.
- Clean the affected area with a degreaser.
- Replace any faulty gaskets or seals to prevent further leaking.
