Paul,

	Re: Bleed valve, that's exactly right.  Same as one on the
bottom of a car rad.  Jim M and I have both used these with no problems.


If the neck of you expansion tank is higher than the elbow, just opening
the valve while filling will do the trick.  (there's a little hole in
the thermostat that will allow air and fluid to pass through it slowly)

Hi, Neil....thanks for your suggestions.  Probably the easiest mod for
me to
make would be to install a 1/4 NPT plug in the top of the elbow (highest
point in the system).  It would probably be fairly easy to finish
filling
the final pint or less with a small hose inserted into that hole.  Not
exactly sure what you mean by a bleed valve. Is this similar to the
bleed
valve that is normally on the lower tank in a radiator in most cars, and
used for draining the coolant from the radiator, or flushing the
radiator?
Thanks again for your comments and suggestions.  Paul Conner
