Anyway what I did when filling up was remove cap from expansion tank and plug from radiator and fill radiator till it was full before replacing plug and topping up expansion tank. squeezed a few of the pipes trying to get any air out and that was it.

Maybe there a better way I don't know but would like to hear what others do to try to prevent air in the cooling system
I just made and installed a "t" piece in the inflow pipe to the heater. Unscrew the plug that I wait until pure coolant and no air passes through the little breather hole I drilled into it. Works everytime!
