- Remove the engine cover if necessary.
- Visually check the serpentine and timing belts for cracks, fraying, or excessive wear.
Replace Damaged Belts:
- If a belt is damaged, loosen the tensioner using the appropriate socket.
- Remove the old belt and install a new one, ensuring proper alignment according to the manufacturer's routing diagram.
- Tighten the tensioner to the specified torque setting.

3. Address Fluid Leaks

Identify and Repair Leaks:
- Inspect the oil pan, gasket, and any seals for leaks.
- Replace any damaged gaskets or seals.
- Clean any spilled fluids to prevent further burning odors.

4. Check Engine Cooling System

Coolant Level and Circulation:
- Inspect the coolant reservoir and radiator for proper fluid levels.
- Replace the coolant if it is low or contaminated.
- Check hoses for any signs of wear and replace as necessary.

5. Electrical Inspection

Check Wiring and Components:
- Inspect wiring harnesses for melting or damage.
- Replace any damaged electrical components or wiring as necessary.
