The fan should always pull the air thru the radiator if on the engine side. If ahead of the radiator, the fan should push the air thru the core. Be aware that electric fans draw a lot of current, and should be controlled by a relay and thermostatic switch . The direction of rotation is determined by the pitch of the blades.

The direction of the fan rotation depends on where you are going to install it and the pitch of the blades. If you are going to install the fan on the motor side of the radiator, it would probably run clock wise, looking from the driver's seat.

I hope you have a 12 volt alternator. I don't see a 6 volt generator keeping up. Mine hardly keeps up with the heater fan and radio on at the same time.

Three months ago I installed a 6 volt alternator and electric fan on my stock 36. Not only did it cure my over heating problem, it cured my long standing charging problem too. Buy a 2 wire altrrnator and mount the fan behind the radiator where it is the most efficent. You don't need 12 volts. Old Henry is right. A 6volt generator won't keep up; a 6 volt alternator will. henery weezer

Here's a 6 volt alternator that looks like a generator. A bit pricy but looks cool: http://macsautoparts.com/early-v8-powergen-alternator-ford-flathead-powder-coated-black-6-volt-positive-10346-82016/camid/F30/cp/JS0R3CHL1129446/ Here's a cheaper 6 volt alternator that looks like one: http://macsautoparts.com/early-v8-alternator-conversion-kit-6-volt-positive-ground-ford-01a-10000-a6v/camid/F30/cp/JS0R3CHL1113138/ The day may come when I am finished "nursing" my 6 volt generator (trying to keep it charging at stop lights) and get the generator looking alternator.

The important info is "two wire alternator". The common one wire unit will usually not accomodate a constant current draw. The common load for an electric fan at 6 volts is above 30 amps. This is one area where a 12 volt conversion starts to make sense. We have installed electric fans in vehicles where there is no room for the stock fan, usually because of an engine transplant. Otherwise, the stock fan should be adequate if the cooling system is in good condition.
