Perhaps David Brodbeck should have said "there's no room for an expansion
bottle NEAR the radiator in the Vanagon."  Add another technical prob - they
would have to have put in hinges and a latch one one of the grills for
access.  Probably cheaper to put it in the back.

I've seen a number of vehicles with expansion tanks lower than the top of
the radiator H20 level - many fords and mercs, for example.  As long as the
outlet from the radiator is controlled by a functioning pressure cap, there
shouldn't be too much worry about it siphoning out coolant when it
shouldn't.
