Clutch Fan disengage speed
« on: September 22, 2010, 04:43:08 PM »
Does anyone know the approximate RPM that a 68 radiator clutch fan disengages.  I'm converting my 68 350 no air to a Vintage Air setup & will be installing the ac radiator & shroud.  Considering a 7 blade clutch fan instead of an electric.  Thanks.

Although a viscous fan clutch never completely disengages, they're calibrated to go to their minimum engagement level over 3500 rpm.
