I have installed a cooling components 2-speed electric fan for my touring engine that also has air conditioning. The standard Model A water pump is too long (I have a Rupert pump) so I installed an 85 HP V-8 water pump with the adaptor. It fits, barely. I am starting to wonder if the V-8 pump is pushing as much coolant as a Model A pump.

The model A engine is 200 cubic inches and the flathead V-8 is 221 cubic inches, but the V-8 uses 2 pumps on the engine. The Model A uses 3 gal of coolant while the V-8 uses 5.5 gal of coolant. Two pumps on the V-8 because it is pushing almost twice as much coolant as a Model A even though their displacements are almost the same??

If anyone has installed an electric fan for the radiator I would like to know what water pump you are using and if it is cooling sufficiently.

Thank you for your assistance, Mark
