2. If oil is leaking, replace the oil filter and tighten loose oil pan bolts.
3. For coolant leaks, replace any damaged hoses or the radiator if necessary.
4. Clean up any spilled fluids with appropriate absorbent materials.

3. Replace Worn Belts and Hoses

Sub-steps:
1. Remove the serpentine belt using a wrench to relieve tension.
2. Inspect the belt for cracks, fraying, or signs of burning; replace if necessary.
3. Inspect hoses for brittleness or leaks; replace any damaged hoses.
4. Reinstall the new belt and ensure proper tension.

4. Repair Electrical Problems

Sub-steps:
1. Inspect wiring harnesses for frayed or damaged wires.
2. Replace any damaged wires with appropriate gauge wire.
3. Check and replace any melted fuses or connectors.
4. Secure any loose connections to prevent future issues.

5. Test Drive and Monitor

Sub-steps:
1. Reconnect the battery and start the engine.
