Sub-steps:
- Examine the ground beneath the vehicle for fluid puddles.
- Identify the type of fluid (oil, coolant, brake fluid) by checking its color and consistency.
- If coolant is leaking, inspect the radiator, hoses, and water pump for damage. If oil is leaking, check gaskets, seals, and oil pan.
Tools Required: Fluid catch pan, rags.

3. Replace Worn Components

Sub-steps:
- If any belts or hoses show signs of wear or burning, remove and replace them.
- Use a socket set to remove any necessary brackets or components to access the belts/hoses.
- Ensure new components match OEM specifications for size and quality.
Tools Required: Socket set, belt tensioner tool (if applicable).

4. Repair Electrical Issues

Sub-steps:
- Inspect the electrical connectors and wiring for any signs of melting or burning.
- Repair or replace damaged wiring using electrical tape or wire connectors as needed.
- Ensure all connections are secure and free from corrosion.
Tools Required: Multimeter, wire strippers, electrical connectors.
