Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Identify and Repair the Leak Source

Coolant Leak:
- Sub-steps:
  1. Remove the engine cover (if applicable) to access hoses.
  2. Inspect the radiator and hoses for cracks.
  3. Replace any damaged hoses or the radiator using a new gasket and hose clamps.
Oil Leak:
- Sub-steps:
  1. Clean the oil pan and surrounding area to remove old oil.
  2. Inspect the oil filter and drain plug for leaks.
  3. Replace the oil filter and/or drain plug gasket if necessary.
Transmission Fluid Leak:
- Sub-steps:
  1. Inspect the transmission pan for cracks or loose bolts.
  2. Tighten any loose bolts; replace the pan gasket if leaking persists.
Brake Fluid Leak:
- Sub-steps:
  1. Inspect brake lines for corrosion or damage.
  2. Replace any damaged lines and ensure the master cylinder is not leaking.

3. Refill Fluids

After repairs, refill the necessary fluids to the correct levels.
Use manufacturer-specified fluids for coolant, oil, and transmission fluid.
