The diameter of the fan body should be 305mm in diameter.  This is for the
450 watt fan that was used on 87-91 Vanagons with A/C.  If this is the fan
that you have then it is plenty of flow (the thing is like a hurricane).
Anything larger and when it kicks in the van won't need a waterboxer motor,
it will be sucked along by the negative pressure vortex created by this fan.

Subject: What is the size of the cooling fan behind the radiator?

I would like to know what the size of the fan is from someone that has a fan
off and can get to it.  I am looking to change out to a higher flowing fan
to
improve A/C cooling in the heat of AZ.

Thanks,

Robert
