Not common, or there would be a FAQ fix on it in
vanagon.com

Have you tried putting 12 volts directly from the
battery??

No cable is commected to this valve, it is done by
hand.

Could be either.  I called around to radiator shops
and  asked who would test the core for free.  Most
wantaed CDN$10, but one said 'sure, bring it on down'.
 so I did, and  he showed the leak to me.  The O-ring
is not very substantial, I tried gasket goop in there
to try and beef it up a bit, but I have yet to install
it.  M
