Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface and allow the engine to cool completely.
Disconnect the negative battery cable to ensure safety.

2. Locate the Leak

Use a flashlight to inspect all coolant-related components.
If necessary, pressure test the cooling system to pinpoint the exact location of the leak.

3. Replace Damaged Hoses

Tools Required: Hose clamp pliers, socket set
Loosen the clamps on the damaged hose and carefully remove it.
Install the new hose by sliding it onto the fittings and securing it with the clamps.
Ensure the clamps are tightened to prevent future leaks.

4. Repair or Replace Components

If the leak is from the radiator or water pump:
- Tools Required: Socket set, screwdriver set
- Drain the coolant from the radiator using the drain plug.
- Remove the radiator or water pump by disconnecting hoses and electrical connections, then unbolting it from the engine.
- Replace it with a new unit, reassemble, and secure all connections.

5. Refill the Cooling System

Tools Required: Funnel
Refill the cooling system with the recommended type of coolant (e.g., Ford Specialty Green Antifreeze).
Start the engine and allow it to reach operating temperature to circulate the new coolant.
Check for leaks around the repaired areas.
