Not saying that I have heat problems with no water pump, but my fan does not look 1923. It looks more like a 1920s house fan (the blades) Then I got to
looking at my 1947 tractor. The tractor 4 blade fan
moves a lot more air. Both seem to be turning the same rpms at idle, both are just about the same or close diameter. Im just wondering what if? anyone
done that or I'm just blowin smoke.
M '17 Torpedo Runabout has a 6 blade fan of unknown origin mounted to a home made ball bearing hub.
Unless you do parades or get stuck in traffic at <5 mph, you don't need no steenking fan.
