Re: Change of radiator core affecting cooling performance in 1949, 23rd series

The electric fan in front might be an interesting experiment. I know some have added radiator shrouds on the cars to make the original fans more efficient. On postwar AC cars, in addition to the heavy duty fan, they also used a thicker radiator having more cores. Prewar AC cars seemed to only need the larger fan.

I must confess to not totally following the slow water flow theory but then I am not that well versed on some things. I would think it just the opposite. Assuming the passages thru the cores are the same size and the only difference between the large and small radiator is more cores, It seems with the larger radiators there would be more channels so the flow thru would be faster. I could see with flow being faster, the water is passing thru so quickly the heat is not being extracted which I believe was a problem with some Ford models of that era.
