You might want to look into the technical page of this web site:

This product actually has a warning on it to be careful about mixing with
prescription medicines because it can accentuate a drugs affect.

The founder had a background in petroluem and per the web site:

Years of searching for relief from fibromyalgia by the company's founder
resulted in the development of proprietary technologies to manipulate the
structure of H2O molecular clusters.  These new smaller clusters allow for
extremely rapid absorption by the cells (end quote).

So the Vanagon point is - this stuff is expensive - if you were to try this
in your coolant tank - you would spend a lot of money....

And another thing to consider - if using tap water introduces salts into
your Vanagon that (speed up/enable/aid) corrosion through electroysis, AND
you add water wetter - then is water wetter improving not only the cooling
ability of your van's coolant system but also the corroding ability of the
salts since in the very least, there is more metal to water contact, or is
there some reason that the reverse is true....

I heard once that Vanagons did NOT have head problems in Europe - was that
true.....?
