If your radiator fan on your van is similar to the one on a Jetta, this is
not a water hose connection, but rather a place where a "cooling air" tube
should be affixed. On the Jetta, the tube runs to in front of the radiator
on the drivers side, and supplies cool air to the innards of the electric
fan motor.

If you decide to route your coolant through this, keep us posted. :)

Subject:        '87 2.1L rad. fan hose nipples?

was flushing and filling the coolant system this weekend (among $300 and 40
hours of other things) and noticed what look like coolant hose
input/outputs on
the back of my radiator fan.  Anyone know what these are?  are my nearby
heater-core lines supposed to run into the back of the radiator fan?  never
heard of such a thing, but then again we are talking vanagon here.  Also,
the
nastiest discharge in the entire cooling system was found in the overflow
bottle; there was boil-over sludge clogging the rad. cap, overflow hose,
and
overflow botle.
