2 fans better than 1?

[LameHoof65]

I am sure this has been covered before----and I have thought about it numerous times. Before this last rebuild, I had tried a couple of things to keep my engine cool in the heat of an Oklahoma August and had little success, especially while running the AC or when in heavy traffic. So, I bought a 3 core from dallas mustangs and thought it and a new thermostat would solve my problem---but it did little to help.. So I thought maybe an electric fan on the outside of the radiator and the original fan on the inside would keep it cooler....but of course I will be losing some of the hp benefit with the engine fan still running, right/wrong---not worth it??

Do you have a fan shroud? If not, they help a LOT.

An electric fan is supposed to be better than an engine fan, especially an unshrouded one - and a puller electric fan behind the radiator is supposed to be better than a pusher in front, but I don't see why.

If you've got the room behind the rad (with the engine fan removed), I'd do that - but if not, then put one in front and see what happens with and without the engine fan.

also try a flex fan i hear they are supposed to work pretty well just make sure u dont get a cheapo deapo one

You gotta watch out for those flex fans, they're known to have fan shrouds break off and go flying through the hood.

On my setup I have a 3-row radiator, a stock style fan and a pusher electric fan in front of my radiator that only comes on when I turn my A\C on. Also a 180 thermostat. It keeps things pretty cool, even out here in AZ.

Thanks for the replies, yea, I have heard bad stuff about high reving engines and the flex fans---probably will not go that route. No factory shroud but I had a fabricated one that helped a bit---enough to know it does help. Looks like josh1966 has the answer. Josh--I guess you just connected the fan to the AC switch with a fuse for load?

I would like to do a thermostat, so it will come on if I am idling in traffic. I thought the thermostat would come with the fan? No, probably not---where would I pick it up and how hard would that be.
