Jay,
   air can get trapped in a hose junction, the heaters
as well as in the radiator.   In very rare cases it
can get trapped in the waterpump itself.   The point
here Jay is that when you empty and fill your cooling
system you want to purge the system with one  complete
cycle of flow which passes through all the hoses and
heaters and pipes.   You need not get all of the air
but just move enough to bleed out the trapped air.
Small bubbles will bleed out over time.   The only
certain way to know this is accomplished is if the
hoses up front get hot which is more important than
the speed of the engine.
