G12 is VW OEM antifreeze, the successor to G11 which was used from the
beginning of time to 1997.  I don't use non-OEM antifreeze in any of my
vehicles.  I was only asking because G11 is hard to find anymore, and
generally special order only.  Yes, I do plan to flush this system thoroughly,
seeing as that the van has been sitting since 1999.
