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 avoid any electrical mishaps.

2. Identify and Repair the Leak

A. Engine Oil Leak

Locate the source: Check the oil pan, filter, and valve cover gaskets.
Replace gaskets: If a gasket is leaking, remove the old gasket and clean the surface. Apply a new gasket with appropriate sealant.
Tighten bolts: Ensure all bolts are tightened to the manufacturer’s specifications.

B. Transmission Fluid Leak

Inspect transmission pan: Look for signs of leaks around the pan gasket.
Replace pan gasket: Drain the transmission fluid, remove the pan, clean the surfaces, and install a new gasket.
Check seals: Inspect and replace any leaking seals (input/output shaft seals).

C. Coolant Leak

Examine radiator and hoses: Look for cracks or loose connections.
Replace damaged hoses: Cut out the damaged section and replace it with a new hose, securing it with clamps.
Fix radiator leaks: If the radiator is leaking, consider using a radiator sealant or replacing the radiator if the damage is severe.

3. Refill Fluids

Refill engine oil, transmission fluid, or coolant as necessary to the correct levels.
