I haven't done it yet, but I plan to give these directions a whirl:

I don't know if a flush with a garden hose is a good idea. I thought you
were supposed to do it with distilled water or deionized water. Tap water
can have some stuff in it (so it's good enough for us to drink, but not good
enough for the vanagon's cooling system??).
And here's a another contraption that just might work for a flush or a
refill - the "Libby Bong":

Best of luck,
