Brian, have you searched the archives for coolant bleeding procedures?  It
sounds like air in the system. I just flushed my system and when adding
coolant to the expansion tank it went in reeeeeally slooooowly ...took a
clean piece of little hose and blew GENTLY on closed expansion cap to help
push fluid in and air out-- out the open front radiator bleeder valve.
Have you been opening that valve to allow air to escape?

There are several good methods of dealing with getting coolant in and out
in the archives;
I recently used the directions Doktor Tim gave Dec 2001
http://gerry.vanagon.com/cgi-bin/wa.exe?A2=ind0112C&L=vanagon&P=R10730
(that should link right to in archive)

Check that out and then see how your method compares.  You might see where
you missed something. If not, then maybe someone can speak to the heads
question.
