Mark,
I have a home-made "tool" for helping bleed the cooling system that could
probably work for your needs also.  Just buy a schraeder (tire) valve with
a surface mount fitting, and a spare burp tank cap (both should be
available at FLAPS).  Drill a hole in the top of the cap and install the
schraeder valve there.  Then you can use a bicycle pump to pressurize the
cooling system to 10psi or whatever, wait a while and see if it held
pressure.  Hope it helps.
best,
