Fan Blade orientation
Working on an over heating problem with a recent complete restoration (1930) - gets hot and boils over within about 10 miles @200°+ - and noticed the (4) fan blade looking like it’s installed backwards - at least to me.
Looks like it is cupped backwards with the ribs to the engine ??
What is the correct orientation ?
Don’t know if this will greatly improve cooling, but it looks wrong to me. Haven’t found any manual or parts pic showing the orientation of 4 blade fans.
