Solution

1. Preparation

Tools Required: Jack and jack stands, fluid catch pan, wrench set, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent electrical hazards.

2. Identify the Source of the Leak

Place a clean catch pan under the suspected leak area.
If coolant is leaking, remove the front trunk (frunk) cover to access the cooling system.
If brake fluid is leaking, inspect brake lines and the master cylinder for cracks or damage.

3. Replace Damaged Components

Coolant Leak:
- If a hose is damaged, loosen the clamps with a wrench, remove the hose, and replace it with a new one. Reattach the clamps and refill the coolant.
Brake Fluid Leak:
- If the master cylinder is leaking, remove it by disconnecting the brake lines and unbolting it. Replace it with a new unit, ensuring to bleed the brake system afterward.
Transmission Fluid Leak:
- If the transmission pan is leaking, drain the fluid, remove the bolts securing the pan, and replace the gasket. Reinstall the pan and refill with the correct transmission fluid.

4. Refill and Test

After replacing any damaged parts, refill the respective fluids (coolant, brake fluid, or transmission fluid) to the appropriate levels.
Reconnect the battery and start the vehicle, monitoring for leaks.
