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 if working on electrical components.

2. Identify and Repair Leak Source

A. Oil Leak

Inspect the oil pan for cracks or loose bolts.
Tighten or replace bolts as needed.
If the oil pan is damaged, remove it and replace with a new gasket and pan.
Refill with appropriate oil type.

B. Coolant Leak

Check hoses for cracks or loose connections.
Replace any damaged hoses.
If the radiator is leaking, drain coolant and replace the radiator.
Refill the system with the correct coolant mixture.

C. Transmission Fluid Leak

Inspect the transmission pan and gasket.
If the gasket is leaking, replace it after draining fluid.
Tighten any loose bolts on the transmission pan.
Refill with the correct transmission fluid.

3. Clean Up

Clean any spilled fluid on the ground and under the vehicle to prevent slipping hazards.
Dispose of old fluids properly according to local regulations.
