I use the Motive European power bleeder (model 0100) on my hydraulic
systems and love it.  I paid just over $40.00 for mine and they're shown
on Motive's site for $49.95 (plus shipping).  Sometimes you can find
them on eBay for less than what Motive is asking.

I don't see why such a power bleeder couldn't be used (with a modified
pressure cap) to bleed your cooling system.

Of course, you could always make your own, too.

The brake fluid reservoir cap shown in the 2nd link (GM) is NOT for
Vanagons.  You would need a 45mm cap such as are found on Alfa Romeo,
Audi, BMW, Fiat, Mercedes, Peugeot, Porsche, Renault, SAAB, Volkswagen,
  and Volvo.
