Hi  DT,

If I understand your query, you'd like to have a 12v means of circulating
coolant.  This would allow you to rig up some type of external heat source,
say a propane burner with a pot of water on it, and then your van's coolant
going though a coiled copper pipe inside the pot or something to that Idea.

Well, I've located a 12 volt pump that is on the part book or micro fiche
section of 150-50, it's referred to as a additional water pump thermostat for
vehicles with air conditioning.  Perhaps this will be helpful.

BTW, I just got this book from Bjorn, it's a Genuine Parts Illustrated
Catalogue, I love it.  I think he has a few left.

Sincerely,

Mark Keller
