Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the engine is cool before starting any work.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Coolant

Tools Required: Radiator funnel, coolant catch pan, socket set
Drain the coolant from the radiator using the drain valve located at the bottom.
Open the radiator cap and allow the system to fully drain. Dispose of old coolant properly.
Refill the system with the appropriate type and mix of coolant for the Ford F-150.

3. Replace Thermostat

Tools Required: Socket set, gasket scraper, torque wrench
Remove the thermostat housing bolts and take off the housing.
Remove the old thermostat and clean the mating surfaces.
Install the new thermostat ensuring it is seated correctly.
Reattach the thermostat housing and torque to specifications (typically around 89 in-lbs).

4. Repair or Replace Hoses

Tools Required: Hose clamps, pliers, cutting tool
Inspect all coolant hoses for cracks or leaks.
Replace any damaged hoses with new ones, ensuring proper fit and secure them with clamps.

5. Inspect and Clean Radiator

Tools Required: Hose, soft brush
If the radiator is blocked, remove debris with a soft brush.
Flush the radiator with water through the top and drain from the bottom if necessary.

6. Refill and Bleed Cooling System

Refill the system with coolant as specified.
Start the engine and let it idle with the radiator cap off to allow air to escape until the thermostat opens.
Keep topping off coolant as needed until no more bubbles appear.
