RE: Electric Cooling Fans

["Rick & Lori" <trinitygadget@alltel.net>]

Bob--Possibly one reason is that in the pusher configuration, all the fan
hardware is directly in the path of the oncoming air and consequently
blocks some of it from entering the radiator.  An additional reason I think
is the pusher configuration is achieved by simply reversing the fan blade
hub on the puller fan.  Perhaps the fan blades were designed for optimum
pulling, not pushing, which is not entirely recovered by hub reversal.
