My 2 cents worth:

I today finished changing the rear heater core.  It
only took 3 weeks (fast for me).  I had a lot of
distractions.

Anyway, I took out the original heater core and
replaced it with a new dealer furnished heater core.
Our friends at VW updated the heater core, the new
model does not have a bleeder port (the old did).  The
parts supplier to VW changed the mold and eliminated
the bleed port.  Darn, I really liked the bleeder vent
concept.  You could use the port to fill the heater
core with coolant and then bleed out the air with the
engine running.  But alas, no more.

First I connected the lower heater hose to the new
heater core.  Then I filled the new heater core with
water using a flex neck funnel at the top hose
connection.  Then I connected the top coolant hose to
the heater core.  I hope that I filled the coolant
system.  I started the van and ran it at idle for 15
minutes to check for leaks.  The new heater core
belched out plenty of heat.  The vehicle did not
overheat so I assume that I let no aid bubbles into
the coolant system.

I will keep my eye on it for the next few days, and
then assume another job well done.  Good luck to all
who attempt this repair.
