Fan Clutches were installed on a few JH roadsters as part of dealer-added Air Conditioning packages; and of course to all of the GTs which came with factory air.  The standard fan should be a strong yellow color with relatively few wide blades, while the A/C equipped cars had a white fan (plus fan clutch) with a larger number of narrow blades.

The biggest concern with a factory fan (which provides PLENTY of flow) is damage to the water pump.  An out-of-balance fan will stress the water pump bearings and cause premature failure.
