Believe it or not, the system will purge itself after small amounts of
coolant loss.  I've done it many times--after rear heater core
replacement, heater valve replacement, t-stat replacement, even after
replacing the expansion tank; just make sure the overflow bottle is up
to the full mark and drive it.  In a day or two you will notice that the
level has dropped, indicating that the air has been replaced with
coolant.
