From the service manual:
Cooling System Filling and Bleeding
NOTE: Have an adequate amount of Motorcraft® Orange Antifreeze/Coolant ready to fill the cooling system. Once the
pumps are activated, the coolant level in the degas bottle will fall very quickly. Do not allow air into the cooling system. The
entire cooling system holds 15L (15.8 qt).
1. WARNING: Before beginning any service procedure in this section, REFER to Safety Warnings in
section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.
Refer to: Engine Cooling System Health and Safety Precautions (100-00 General Information) .

3. NOTE: Once the scan tool begins the coolant fill, verify 3 valves are at 50% (raised notch is in the middle) and 3
pumps are running by feeling that each pump is vibrating.
Using a scan tool, navigate to Cooling System Fill and follow the on-screen instructions.
4. Once the Cooling System Fill is complete, using a scan tool, navigate to Cooling System Purge/Degas and follow
the on-screen instructions.
Not that helpful. The coolant flush procedure is more comprehensive, but that is to get coolant out, not in.
Consider a vacuum bleeder. This one is cheap.

Its $28 on ebay.
These things work wonders. It uses shop air blown across a venturi to create a vacuum, that is attached to the top of the degas bottle. By putting a low-pressure environment there, the air (that is at atmospheric pressure) in the rest of the coolant system expands, and in doing so finds its way out of nooks and crannies. As the air leaves that spot, it is replaced with coolant. With the vacuum bleeder on, turn on the pumps and open the valves, and you should air pocket free in about 20 minutes.
