remove readiator cap, put a bucket underneath to catch the coolant overflow, (bad for the environment), let engine idle for 30mins or longer, coolant would go down as air space is displaced by coolant in the system, keeping the radiator neck full.
Make sure the thermostat is opened, the upper readiator hose should be hot after a while.
somtimes it takes a long time to completely get rid of air in the cooling system.
That is it.

Thanks for the response.
So do I have to actually refill the radiator once the thermostat opens? I know once it opens, it sucks coolant into the engine but with the radiator cap off, it also sucks air.

no, it won't suck air in. Since coolant flow from top to bottom of the radiator into the engine. Just keep it top up with coolant, that is it.
You can also go buy a kit for this purpose. It is like a big funnel with a readiator cap adoptor, so that you can keep the coolant full with no overflowing. You can find then in the big chain auto parts store.

I did read that the system does purge itself via the over-flow tube/tank but I think initially, it's good to purge the system as best as you can if you're changing your coolant.

Usually the need to "burp" the system is caused by the thermostat not opening soon enough because the coolant is not touching it. This can cause the engine to overheat. The solution is to install a thermostat that has a small hole in it to allow air to escape before the thermostat opens. The OEM and Motocraft has this hole but many aftermarket thermostats do not. I recommend installing one with the small hole. The Motocraft is a much higher quality thermostat than many available at auto parts stores.
The other procedures in this discussion thread are also necessary to complete the coolant fill.
