Had this same problem with my 85 the first summer I owned it. I dropped the
spare tire, pulled the valve out (very easy, just two spring clamps, use
vice grips) and although it looked like it closed fully, it still leaked
under pressure.  Replaced it with one from the bus depot (only $7, very
common VW part) hooked the cable back up and no more heat in the summer. The
BEST thing I ever did to the van, because the westy AC doesn't work well
with the heat on.

Once you have done this you will know the easiest way to flush the coolant
out. Buy one of the cheapo T fittings at your FLAPS and put it in place of
the heater valve, no cutting of the coolant hoses required, open the rear
heater valve, turn on the hose and flush out that nasty old coolant.
