Folks,
The Mudskipper is heading to my local Vanagon expert for a complete coolant 
flush-n-fill on Monday BUT the coolant is getting low and I'm heading on a 
roadtrip this weekend.  I have no idea what kind of coolant the PO put in 
there: it's green, but in our pre-sale discussions he seemed acutely aware of 
the requirement for phosphate-free coolant.
So: what would you top the tank off with?  I've got three bottles of OEM blue 
goo ready for Monday, but I understand that mixing coolant types is bad news.

Best,
d.
