Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Identify the Fluid Type

Sub-steps:
- Use a clean cloth to dab the fluid to determine viscosity and color.
- If the fluid is clear and thin, it may be windshield washer fluid; if it's green or orange, it might be coolant; dark brown indicates engine oil.

3. Repair Fluid Leak

Sub-steps for Common Fluid Types:
- Coolant Leak:
  - Locate the source by tracing hoses back to the reservoir and radiator.
  - Replace any damaged hoses or tighten loose connections.
  - Refill coolant as needed and check for leaks after repairs.
- Engine Oil Leak:
  - Inspect the oil pan, valve cover gasket, and oil filter for leaks.
  - Replace gaskets or seals if worn or damaged.
  - Ensure the oil filter is properly installed and not leaking.
- Brake Fluid Leak:
  - Check the master cylinder and brake lines for cracks or leaks.
  - Replace any damaged components and bleed the brake system as necessary.
- Windshield Washer Fluid Leak:
  - Inspect the washer fluid reservoir and hoses for cracks.
  - Replace the reservoir or hoses if leaking.

4. Clean and Test

Sub-steps:
- Clean the area around the leak with a degreaser to remove old fluid.
- Refill any fluids that were lost during the repair.
- Conduct a test drive to confirm that the leak has been successfully resolved.
