The air will bleed out wit the engine running the heater on and the radiator cap off, you can buy radiator neck extensions that clip on the radiator with a container that will hold coolant above the radiator. This in efect becomes the highest poit of the cooling system and all the air will bleed up, you may get some air pockets, but these will only be bubbles, these will bleed out into the radiator with in a few hrs or so, just re check the coolant the next day and all should be good, that is if there is no problem with the system.
