Engine Cooling System Draining, Vacuum Filling and Bleeding: Filling

Filling and Bleeding with a Vacuum Cooling System Filler 

1. • NOTE: Use the correct coolant. Do not mix coolant types. Mixing coolant types may degrade the coolant corrosion protection and may damage the engine or cooling system. For the correct coolant specified for this vehicle, refer to Specifications .
     NOTE: Engine coolant provides boil protection, corrosion protection, freeze protection, and cooling efficiency to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.
     NOTE: Do not add alcohol, methanol, or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
     NOTE: Ford Motor Company does NOT recommend the use of recycled engine coolant since a Ford-approved recycling process is not yet available.

     When adding or topping off the engine coolant:

   • Measure the coolant concentration in the vehicle. Use Special Service Tool: ROB75240 Coolant/Battery Refractometer (Fahrenheit).
   • Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.
   • Add, top-off or adjust the coolant to the correct concentration. Refer to: Specifications .

2. Close the radiator drain valve.

5. Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the system. Use the General Equipment: Cooling System Vacuum Tester and Refiller
6. Vehicles driven year-round in non-extreme climates should use a 48/52 to 50/50 (freeze protection -34°C to -37°C [-30°F to -34°F]) mixture of engine coolant and distilled water for optimum cooling system and engine protection.

7. Fill the degas bottle to the MAX FILL line.
8. Install the degas bottle cap until it contacts the hard stop.
9. Turn the climate control system off.
10. Start the engine and increase the engine speed to 3, 500 rpm and hold for 30 seconds.
11. Turn the engine off for and wait for 1 minute to purge any large air pockets from the cooling system.
12. WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

    Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle.

13. Start the engine and let it idle until the engine reaches normal operating temperature and the thermostat is fully open. A fully open thermostat is verified by the cooling fan cycling on at least once.
14. Increase the engine speed to 3, 500 rpm and hold for 30 seconds.
15. Allow the engine to idle for 30 seconds.
16. Turn the engine off for 1 minute.
17. Repeat steps 14 through 16 a total of 10 times to remove any remaining air trapped in the system.
18. WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.
    NOTE: The coolant should be at room temperature when checking the level.

    Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle.

19. Install the pressure relief cap.
