Solution

1. Preparation

Tools Required: Socket set, screwdrivers, coolant catch pan, safety gloves, safety goggles.
Allow the engine to cool completely before proceeding.
Disconnect the battery to ensure safety during repairs.

2. Identify and Repair Hose Leaks

Sub-steps:
1. Remove any engine covers or components obstructing access to coolant hoses.
2. Inspect each coolant hose for signs of wear or damage.
3. If a hose is found to be leaking, loosen the clamps and remove the hose.
4. Replace with a new hose, ensuring it is the correct size and type.
5. Reattach the clamps and ensure they are securely tightened.

3. Replace the Water Pump (if necessary)

Sub-steps:
1. Drain the coolant from the radiator using the drain plug and catch pan.
2. Remove any components obstructing access to the water pump (e.g., belts).
3. Unbolt the water pump from the engine block and carefully remove it.
4. Clean the mounting surface on the engine block and install a new water pump with a new gasket.
5. Torque the water pump bolts to manufacturer specifications.

4. Repair or Replace the Radiator (if necessary)

Sub-steps:
1. Inspect the radiator for any signs of cracks or corrosion.
2. If a leak is detected, remove the radiator by disconnecting the hoses and unbolting it from the support.
3. Replace with a new radiator, ensuring it matches the specifications for the 2015-2020 F-150.
