Which one of your cars are you doing this too?

You do not want a fan infront of the radiator as a pusher. You NEVER EVER want a fan in front of the radiator as a PULLER.

As soon as you start driving, the fan will never be able to pull air against the air movement from driving.

If you have an overheating problem, I recommend getting an alluminum Radiator for about $350.00

Or keep what you have, and use a flex fan with shroud. The cars you have listed should not have any problems cooling any engine you have, just fix what you have for best results.

If your looking to save 10 - 15 HP, most of that savings dose not really happen, unless you have a really crappy mechanical fan now.

 

I had my fan mounted in front of the radiator for a few years as a pusher, and it worked fine. Don't put a 'puller' in front of the radiator. Most fans are reversible and can be used either way, just flip the blade around and reverse the polarity to the fan motor....should be fine.

 

An electric fan mounted in front of the radiator is a pusher, behind the radiator a puller. A front mounted electric fan asm (including shroud and/or guard/brackets) actually impedes air flow over the core. You want it as a puller. The MARK VIII swap is the most popular and requires a big ALT.

 

no problem mounting in front as a pusher, its not as effective as a puller on the other side but it will work if you need to do it that way.

I have twin pushers mounted in front of my radiator and they work perfectly.

 

Thanks for the replies, my Galaxie will be getting a stroker big block soon (hopefully within about 2 months) and i know that i will have to upgrade my cooling system. As for the $350 radiator suggestion i already bought a nice universal one for $152 from summit (theyre made by Northern i believe) im just not 100% sure how much room ill have in front of the engine, but the explanation about how the incoming air will negate the fan trying to pull the air while driving pretty much answered my post. i think The blades on the Taurus/Mark IV fan are shaped in a way that reversing the polarity wil not work too well,i might be wrong on that though. Also do you guys think a 100amp alternator will work with this fan ( i know this fan draws MAJOR amperage,i heard a bit over 30amps after the spike), i wont be running an electric fuel pump or electric water pump, so pretty much this will be the only accessory that will tax the alternator,oh yeah it has a radio but nothing fancy (no subs or amps) and a seldom used heater that i might yank (mild san jose california).

anybody?

 

So, I did read your original post correctly, the way most of the other folks answered suggested I missed something. They must have though you meant you had a pusher fan.

You want to use that fan as a puller in front of the radiator. That will not work.

As far as the alltinator, most fans draw near 10 - 15 amps, some high power fans draw 20 - 30 amps. I would think a standard 50 amp altinator with a 5 -10 amp ignition system and an electric fan would work fine. Should have plenty of extra power for lights and wipers....
