Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the battery to prevent electrical issues.

2. Coolant Level and Leak Check

Required Tools: Coolant funnel, flashlight.
Remove the coolant reservoir cap and check the coolant level.
If low, fill with the correct type of coolant (Ford-approved) until the proper level is reached.
Inspect hoses and connections for leaks; replace any damaged hoses.

3. Thermostat Replacement

Required Tools: Socket set, torque wrench.
Remove the thermostat housing by unscrewing the bolts (typically 10-12 Nm torque).
Take out the old thermostat and clean the mating surfaces.
Install the new thermostat (ensure correct orientation) and reattach the housing, tightening to the manufacturer’s specifications.

4. Radiator Flushing

Required Tools: Radiator flush kit, garden hose.
Disconnect the lower radiator hose to drain coolant.
Use a radiator flush solution according to product instructions and run the engine as directed.
After flushing, reconnect the hose and refill the radiator with fresh coolant.

5. Cooling Fan Inspection

Required Tools: Multimeter.
Inspect the cooling fan for damage and ensure it spins freely.
Use a multimeter to check for power to the fan when the engine reaches operating temperature.
Replace the fan motor if it does not operate correctly.
