Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Allow the engine to cool completely before starting work.

2. Identify and Replace Damaged Components

Engine Oil Leak:
- Inspect oil pan gasket, valve cover gasket, and oil filter for leaks.
- If damaged, remove the old gasket or filter.
- Clean surfaces, apply new gasket material or install a new oil filter, and tighten to manufacturer specifications.
Coolant Leak:
- Check radiator, hoses, and water pump for leaks.
- Replace any damaged hoses or clamps as needed.
- If the radiator is leaking, drain coolant, remove the radiator, and replace it with a new one.
Transmission Fluid Leak:
- Inspect the transmission pan and seals.
- If the pan is damaged, replace it by removing the bolts, cleaning the surface, and installing a new pan with a gasket.
Brake Fluid Leak:
- Inspect brake lines and master cylinder for leaks.
- Replace any damaged brake lines and ensure all fittings are tight.

3. Refill Fluids

After repairs, refill any low fluids to the appropriate levels (engine oil, coolant, transmission fluid, brake fluid).

4. Clean the Area

Clean the area where the leak occurred to monitor if the leak resurfaces.

5. Test Drive

Drive the vehicle for a short distance and check for any new leaks or warning lights.
