VW sells Autobahn phosphate free coolant (what I use) other mfr's sell
some also, I believe Prestone sells some, check the label, it should
explicitly say "Phosphate Free".

Bleeding the system in a Vanagon is a fairly involved task.  I've done
it myself before, but it is really a 2 man task.  The bently has an
excellent procedure for bleeding the system, I believe someone posted it
a while back, it should be in the archives.  The only odd tool /
difficult part is raising the front of the van some 15" or something
like that, I used a hydraulic lift last time, a floor jack and a jack
stand also works well.
