Jim,
True, you can just add water, but think of the corrosion sizzling on the
old Vanagon's notoriously corrosion-prone heads as you are motoring
along without the corrosion inhibitor package. If you read the bottle on
the Prestone long-life Phosphate Free coolant, it reads that it cannot
mix with ethylene glycol or anything other than itself. In fact,
Prestone has colored it orange to remind users it cannot mix with
anybody elees green or pink coolant.
