Sub-steps:
1. Remove the serpentine belt using a socket to relieve tension.
2. Inspect the belt and replace if cracked or frayed.
3. Remove and replace any hoses that show signs of bulging or cracking.
4. Reinstall the serpentine belt according to the routing diagram.

4. Repair Electrical Issues (if applicable)

Sub-steps:
1. Inspect wiring for any fraying or melting, especially near heat sources.
2. Tighten or replace any damaged terminals or connectors.
3. Use electrical cleaner to remove corrosion from battery terminals.

5. Clean Exhaust System (if applicable)

Sub-steps:
1. Inspect the exhaust system for any signs of melting.
2. Remove any debris or foreign materials that could catch fire.
3. If necessary, replace damaged exhaust components.
