I am looking to upgrade to electric fans for my nova. there going to be going on my stock radiator since it works excellent and i had a few questions before i go any further on it

how much of a cfm fan should i be looking for?

one or two fans?

do i need a fan shroud?

what other things do i have to buy for it? (to wire it up)

can i wire it in with a stock intake?

where do you buy the switches that come on at a certain temperature?

can you change the temperature at which they come on or is it a set temp?

You know, you could go the cheap and effective route.:yes: Wanna know what it is? Go to a junkyard($35-70) or buy a new($100) electric fan for a 3.8L Ford Taurus from the late 80s/early 90s. The LOW speed on a Taurus fan flows almost as much air as this $210 dual fan unit!:eek: http://www.jegs.com/i/JEGS/555/52116/10002/-1


As for the other questions: As far as I am concerned, there is no "over-doing it." The faster the fans can cool the better. About the fan coming on at different temperatures, you can buy switches that have the fans come on at different temps(though I am tempted to rig mine into a 3-way switch:D). You can buy them at Jegs or about anywhere online if you look. YES you need a shroud to make the fan effective. To wire it, all you need is a power source, ground, switch of some sort, and other basic electrical stuff. It will operate independently of the motor, but make sure you only use a wire that is hot when the ignition is on. Wouldn't want missing fingers:D

About using the stock intake, you may be able to find a water outlet with the correct size hole?


Hope I helped.:eek:

2 speed Taurus fan, $20.00 at wreckers. I had just the be cool aluminium rad and standard mech fan, no go, still hot.
The top L brackets are also from the front cowl of the Taurus I got the fan out of. Low speed 2500 cfm, high speed 4500 cfm, that is big air. Some good links on the site regarding install and wiring. Very simple. :cool:

I had 2 peicies of rubber coated metal, that was very bendable laying around. They are bolted to the botom of the rad frame. They hold the bottom in well. I was going to drill holes and screw the bottom tabs into the fan housing, but it is held fast as is. Which makes for quick removal with the top 2 bolts.
