Re: Correct Mounting of a 1941 120 Fan Blade

You want the blade positioned so when it turns the air is being blown backwards toward the engine. Mounted on the pump, the sort of hollow or concave face of the blade will be toward the engine. The leading edge is near the radiator and bites into the air and curves it until the trailing edge can force it toward the engine. If you mount incorrectly, it will try to blow air forward against the airstream.
