Cooling Fan Rotation

Anybody know what way works best for cooling? Fan blowing towards radiator or blowing towards engine?

Re: Cooling Fan Rotation

fans pull air through radiator and blow toward engine,
otherwise they would be working against ram airflow
when car is in motion.Also puller fans pulling air through
a radiator are much more effective than pusher fans
blowing air through the radiator,the reason is the air
from the discharge side of a propeller fan is rotating like
a vortex and hits the radiator fins at an angle,reducing
airflow.

Re: Cooling Fan Rotation

Thats what I thought. I have all my F-bods set up that way. My little sister has hers the other way. She says she never had an over heating problem. Thanks for proving me right .

Cheers!
