Vanagoners:

        I just replaced my coolant using Mark Magee's method that he posted on
9.24.97 (titled as above.)
        It was so easy that I wonder if I'm missing something. Basically upper
hose to plastic pressure tank is ported to reservior (I, too, used the PVC
pipe) and new coolant is added through the top of the tank, the pressure
cap having been removed.
        I first ran 5-10 gallons of filtered water through the system. The
effluent, at the end, was only slightly blue tinged. I drove the van for a
day, then repeated the operation with my 50/50 Autobahn/filtered water mix.
The resultant coolant is probably less than 50% Autobahn, but I can fine
tune that by adding pure stuff.
        This may not be the best method, but it sure is easy. One person
operation.
        What's the downside?
