Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, wrench set, fluid catch pan, UV dye and light (if necessary), and a clean cloth.
Safety Precautions: Ensure the vehicle is on a flat surface, use wheel chocks, and wear gloves for protection.

2. Fixing the Leak

A. If it’s an Oil Leak

Locate the Leak Source: Inspect the oil pan and gaskets.
Replace Gasket or Seal: Remove the old gasket and clean the surface. Apply a new gasket with the appropriate torque specifications.
- Torque Specifications: Refer to the service manual for proper torque values.

B. If it’s a Coolant Leak

Inspect Radiator and Hoses: Look for cracks or loose connections.
Replace Damaged Hoses: Cut the damaged section out if necessary and replace with new hoses.
Refill Coolant: Use a 50/50 mixture of coolant and water to refill.

C. If it’s a Transmission Fluid Leak

Check Transmission Pan: Examine for leaks at the pan or cooler lines.
Replace Transmission Pan Gasket: Remove the pan, clean surfaces, and install a new gasket.
- Fluid Type: Use the manufacturer-recommended transmission fluid.

D. If it’s Power Steering Fluid

Inspect Power Steering Reservoir and Hoses: Look for cracks or loose fittings.
Replace Damaged Components: Tighten connections or replace hoses as needed.
