Solution

1. Preparation

Gather tools and safety gear.
Ensure the engine is cool to prevent burns.
Disconnect the battery to avoid electrical issues.

2. Identify the Leak Source

Tools Required: Flashlight, mirror (optional).
Use a flashlight to inspect the area where the coolant is leaking.
If necessary, use a mirror to see difficult-to-reach areas.

3. Repair or Replace Components

Hoses: If any hoses are cracked or leaking, remove the damaged hose using a hose clamp tool and replace it with a new hose. Tighten the clamps securely.
Radiator: If the radiator is leaking, remove it by disconnecting the upper and lower hoses, as well as any electrical connectors. Replace with a new radiator and refill coolant.
Water Pump: If the water pump is leaking, remove it by taking off any belts and fasteners securing it. Replace the water pump and ensure the new gasket is properly seated, then reassemble.
Coolant Reservoir: If the reservoir is cracked, replace it. Remove the old reservoir by detaching any mounting clips and hoses, then install the new one.

4. Refill Coolant

Fluid Required: Use the recommended coolant type for the Ford F-150.
After repairs, refill the coolant system with the appropriate mixture of coolant and water.
Bleed the cooling system to remove any air pockets.
