Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool to prevent burns.
Disconnect the battery to avoid electrical issues.

2. Identify and Access the Leak

Tools Required: Pliers, socket set, and screwdrivers.
Use the pressure tester on the cooling system to locate the source of the leak.
If necessary, remove components obstructing access to the leaking area (e.g., air intake assembly).

3. Repair or Replace Damaged Parts

Hoses:
- If a hose is damaged, loosen the clamps and remove the hose.
- Install a new hose and secure it with clamps, ensuring proper tightness.
Water Pump:
- If the water pump is leaking, drain the coolant from the system.
- Remove the water pump by unbolting it from the engine block.
- Clean the mounting surface and install a new water pump with a new gasket, torquing bolts to manufacturer specifications (typically around 18-25 lb-ft).
Radiator:
- If the radiator is leaking, drain the coolant and remove it from the vehicle.
- Install a new radiator and reconnect all hoses and the coolant reservoir.

4. Refill and Bleed the Cooling System

Refill the cooling system with the appropriate type of coolant (typically Ford Motorcraft Gold).
Start the engine with the radiator cap off and allow it to reach operating temperature while monitoring for air bubbles.
Once air is purged, replace the radiator cap securely.
