Tools Required: Socket set, screwdrivers, OBD-II scanner, flashlight.

2. Inspect and Replace Worn Components

Belt Inspection and Replacement:
- Visually inspect all engine belts for cracks, fraying, or signs of wear.
- If a belt is damaged, loosen the tensioner using a socket and remove the old belt.
- Install the new belt, ensuring it is routed correctly and properly tensioned.
Hose Inspection and Replacement:
- Check all hoses for cracks or leaks.
- If a hose is damaged, use clamps to remove it and replace it with a new hose.
- Ensure all connections are secure to prevent future leaks.

3. Address Fluid Leaks

Identify any fluid leaks that may be causing burning smells:
- If oil is leaking, replace faulty gaskets or seals.
- Use a degreaser to clean the area to monitor future leaks.

4. Brake Inspection and Service

Inspect the brake pads and rotors for excessive wear:
- Remove the wheel and check the thickness of the brake pads.
- If worn, replace the brake pads and check the rotors for damage.
- Ensure calipers are functioning and not sticking.

5. Tire and Wheel Inspection

Check tires for signs of rubbing or excessive wear:
- Inspect wheel well clearance and ensure there is no contact with suspension components.
- If necessary, reposition or replace tires to prevent contact.
