I had an electric fan (similar to the one referenced from classic Car World
but from Vintage Air) mounted in front of the radiator as a pusher. It
worked very well for city driving but at high speeds the pancake motor
blocked too much air to cool the hard working engine coolant. A puller fan
is much, much better.
I did not have room behind the radiator, between the water pump pulley and
cooling fins, to mount the fan with pancake motor. To solve the issue, I
installed a 'sidewinder' electric fan behind the radiator. The sidewinder
style has the electric motor mounted off to the side with an enclosed cog
belt running the fan. I clocked the fan so that the motor sits on the lower
left side of the engine. The location required a short extension of the
lower water hose to place the hose behind the fan motor.
The unit that I am using employs a 16" fan with a built in cast aluminum
shroud. On a hot day, When the fan engages, the fan motor runs less than a
minute to cool down the temperature enough to shut down. It produces a
hurricane. The motor draws 19 amps. The engine stays cool at high speeds
without the fan running.
