Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Identify and Repair the Leak

Coolant Leak:
- Inspect the radiator and hoses for damage. Replace any cracked hoses or faulty connections.
- If the radiator is leaking, consider replacing it. Remove the old radiator by disconnecting the hoses and mounting brackets, then install the new one.
Brake Fluid Leak:
- Check the master cylinder and brake lines for leaks. If the master cylinder is leaking, replace it by removing the old unit and installing a new one, ensuring to bleed the brake lines afterward.
Transmission Fluid Leak:
- Inspect the transmission pan and seals. If the pan is damaged, drain the fluid, remove the pan, replace the gasket, and reinstall it, refilling with the appropriate transmission fluid.

3. Clean Up

After repairs, clean any spilled fluid using appropriate absorbent materials. Dispose of used fluids and materials properly.
