If you're facing the front of the engine, the fan spins clockwise right? My alternator fan spins counter clockwise? Or do I have the wrong water pump fan?

Think about that alittle harder,,,it doesn't work that waypauly383k10 said:Flip the fan around![]()

...if your still in doubt,(if its not marked)--just start it up--if it blows towards you instead of the motor,its wrong!.. 
... but simply bolting it on the other way will make it look just as it does now, and still blow the same direction. To actually change the direction of airflow you would have to reverse the rotation of the blade or change the pitch of the blades to opposite of what they are now (but simply "flipping" the blade around doesn't change the direction of airflow.) Just a friendly FYI.diesel4me said:Many fans I've removed have the word "FRONT" stamped into the hub where it bolts on......if your still in doubt,(if its not marked)--just start it up--if it blows towards you instead of the motor,its wrong!..

--when I removed them,thats when Isaw "FRONT" stamped in the hub..

Turns out the guy had mounted the flex fan backwards, Id never noticed, and that first time I got on it it flexed forward enough to chew up the brand new radiator. I can laugh about it now.
