 You mention your van is running noticeably cooler than before you took
coolant out and re-filled?  That IS one of the symptoms of air in the
cooling system.
 At the cost and hassel of re-building a WBX or transplanting in some other
motor, I would error on the safe side.  It takes me all of about 3 minutes
to pop off the grill, remove the bleeder and stick my little (I use a hard
steel brake line mated to the funnel) device in the bleeder hole and pour in
some coolant till a steady stream comes back out.  I did blow a headgasket
once when I was just learning Vanagons (inline VW motor)  running it with
just those symptoms.
   I did a 3000 mile trip with stop leak in that motor, losing coolant and
topping the system each gas stop.  Didn't even make the other gas station
customers angry, I got so fast at doing the 'funnel in the bleed screw'
process.
