1931 Radiator Fan

(and other substitute years)

The proper fan blade for 1931 was a two bladed fan.

Most people replaced this with a four-bladed fan at some point in time.  The cooling improvement is very noticeable.
In later years, this 4-blade fan was the only replacement available from Chevrolet.
