Solution

1. Preparation

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

2. Identify and Fix the Leak Source

Engine Oil Leak:
1. Remove the engine cover (if equipped) to access the valve covers and oil pan.
2. Inspect valve cover gaskets for wear; replace if necessary.
3. Check oil pan for cracks or leaks; replace the oil pan gasket if needed.
Coolant Leak:
1. Inspect hoses for cracks or loose connections; tighten or replace as necessary.
2. Check the water pump for leaks; replace if faulty.
3. Examine the radiator for cracks or damage; replace if needed.
Transmission Fluid Leak:
1. Inspect transmission pan for damage; replace the gasket if leaking.
2. Check the transmission cooler lines for leaks; tighten or replace as necessary.
3. If the transmission pan is damaged, remove it, replace the filter, and install a new gasket.

3. Refill Fluids

Refill engine oil, coolant, or transmission fluid as appropriate, ensuring the correct type is used.

4. Reassemble Components

Reinstall any components removed for inspection and ensure all fasteners are torqued to manufacturer's specifications.
