Inspect the Belts:
- Visually examine the belts for cracks, fraying, or glazing.
- Use a flashlight and inspection mirror to check hard-to-see areas.
Replace Damaged Belts:
- If damage is found, release tension from the belt using a wrench on the tensioner pulley.
- Remove the old belt and install a new belt, ensuring it follows the correct routing.
- Tighten the tensioner pulley to the manufacturer’s specified torque.

3. Address Electrical Issues

Inspect Wiring:
- Look for any melted wires or damaged insulation.
- Use a multimeter to check for shorts or open circuits.
Replace Damaged Components:
- If any damaged wiring is found, repair or replace the affected harnesses.
- Ensure all connections are secure.

4. Check for Fluid Leaks

Inspect for Leaks:
- Look under the vehicle and around the engine for any signs of leaking fluids.
- Pay special attention to oil and coolant, as they can cause burning smells.
Repair Any Leaks:
- Replace gaskets, seals, or hoses that are leaking.
- Ensure all fluid levels are topped off after repairs.
