Solution

1. Preparation

Tools Required: Jack and jack stands or ramps, drain pan, clean cloths, OBD-II scanner.
Ensure the vehicle is on a level surface and secure before starting work on it.

2. Identify Fluid Source

Sub-steps:
1. Use a flashlight to inspect the source of the leak based on the color and location of the fluid.
2. Check common leak areas such as the oil pan, transmission fluid pan, coolant hoses, and power steering reservoir.

3. Repair the Leak

Sub-steps:
1. For Oil Leak:
  - Drain the engine oil if necessary using a drain pan.
  - Replace the oil filter if the leak is from the filter.
  - Tighten or replace the oil pan gasket if leaking from the pan.
2. For Coolant Leak:
  - Inspect and replace any damaged hoses or clamps.
  - Replace the radiator cap if it is not sealing properly.
  - Repair or replace the radiator if leaking from the core.
3. For Transmission Fluid Leak:
  - Inspect and replace the transmission pan gasket if leaking.
  - Check for cracks in the transmission case.
4. For Power Steering Fluid Leak:
  - Replace any damaged power steering hoses.
  - Inspect the power steering pump for leaks.

4. Refill Fluids

Sub-steps:
1. Refill any fluids that were drained during the repair process (engine oil, coolant, transmission fluid).
2. Use the manufacturer-recommended fluids for refilling.
