To address Steve's cause of the diesel Vanagon pump's heat/cavitation
caused erosion, wouldn't switching to a "one belt" system from the
diesel "two belt" setup be the answer.  The pump would then turn
slower.

If you were to do this, you would need a 30mm pump and pump pulley
(biggest diameter that will not rub on the crank pulley), and a non-air
alternator pulley off an A1 or A2 alternator.  This ought to align OK.
We'll want other opinions on the adviseability of doing this though.

Could be that, if the cooling system is doing its job, including a clean
and properly functioning radiator and a quality German waterpump, the
heat/cavitation issue with the waterpump is moot though.
