ok this may seem like a dumb question, but which direction does the clutch fan blow? does it suck air from the engine bay through the radiator or does it suck air from outside through the radiator into the engine bay....i tried to feel which way it blows but im still not sure as the air sorta just swirls around...i have installed a push type thermo fan on the outside of the radiator pushing air in but i'm affraid the 2 fans will cancell each other if the clutch fan blows inside out lol.

It pulls air into the engine bay.

thanks
