Okay lookin at removing my mechanical fan and installing a electric fan or fans. Just wondering how many CFM i would have to push through the radiator to keep it cool. Im mounting the engine in a 79 dodge and the engine driven fan will be too close to the radiator. Its gonna be a mostly offroad truck and see some decent idle times but yet also be a driver when its farm seasonjust wondered if any of you guy have put electric fans on your trucks.

 

as much as possible. some people have got away with lincon mark3 fans from junkyards. the stock fan has a very high cfm. not sure if you tow at all. if u town i wouldnt change it. also some have put 4 fans, 2 pushers(12inch) and 2 pullers(16 inch) and dont have a problem, but they dont tow.
