I have a 1986 vanagon, 2 WD.  I'd like to run some Prestone coolant flush
thru it, as after 170k miles I bet it has some junk in it.

1.  Is it ok to use the Chemical coolant flushes in the Vanagon?

2.  I want to install the Flush and fill kit, the one that hooks up to a
garden hose with a tee fitting (which will be needed to assure all the flush
chemical is removed antifreeze)  I was thinking of putting the hose
connection in line with the rear heater core, under the floor.  Is this a
good location?  anyone use another location?

  thanks  dave
