I went out this morning and took some measurements.

From the tip of the fan blade to the center of the fan is 8". It has four blades.

From the center of the fan to the top of the fins (NOT the top of the radiator) is 13".

From the leading edge of the fan to the face of the radiator fins is 1 1/4".

Maybe the fan is too far away from the radiator? Maybe I need spacers? I don't know how far from the radiator the fans should be.

I didn't measure the pitch of the fan blades.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
