Craig,
I strongly disagree with your method of removing the radiator bleed screw.
 The bolt should be notched down the threads so it only takes half a turn
to burp the system.  As coolant appears close it. No need to fill from
this location. Leaving the screw off while the vehicle cools will only
draw in air as the liquid contracts.
