Sub-steps:
1. Remove the plastic engine cover (if applicable) by unscrewing any screws or clips.
2. Locate the serpentine belt and inspect for cracks, fraying, or glazing.
3. If damaged, use a socket to relieve tension on the tensioner and remove the belt.
4. Install a new serpentine belt following the routing diagram usually found on the engine bay or in the owner's manual.
5. Tighten the tensioner to the specified torque value (consult the service manual for exact specifications).

3. Check Electrical Components

Sub-steps:
1. Visually inspect all wiring harnesses for signs of melting or damage.
2. Disconnect any damaged connectors or wires.
3. Replace damaged wiring with appropriate gauge wire and connectors.
4. Reconnect the battery and test electrical systems for functionality.

4. Address Any Fluid Leaks

Sub-steps:
1. Conduct a thorough inspection of the engine and transmission for any fluid leaks.
2. Identify the source of the leak and replace any faulty gaskets or seals.
3. Clean any spilled fluids to prevent future smells or hazards.
