ok so here it is its kinda too late for this but i bought an electric fan off ebay it 14in i think 2000cfm.... how much airflow is needed to properly cool a 22re ? ive always heard of the ford taurus fan mod but dont know how much that fan actually pushes any one with an electric fan im interested in what you went with?

 

Think your fan is way on the low side. seems the flexalite 165 is around 2800cfm and the taurus is around 4000cfm. Don't remember numbers for sure but someone else will surely chime in.

caution on controllers as I've burn up three.

 

i bet you will know when you start watching your temp gauge..

 

I have the taurus fan in mine. not sure of the cfm rating but it works great. I used a control from dc controls. they are very nice solid state controls but will take about a month to get it. worth the wait. I got my fan for about 40 at the local wrecking yard.

 

i could imagne you could use just about any thermosatci fan switch to control your fan or you could just have a simple toggle siwtch but that would just look trashy..

 

um it's actually a good thing to have both a thermo switch and a toggle switch. If you wheel enough and do water crossings you will learn that looks isn't everything. Functionality is what counts in the end.

 

Yup get a switch and thermometer control. Do not try to run the fan without a relay.

 

To be fair the Taurus fan does not need to run on High to keep the 22re cool. Does anyone know the CFM of it on slow?

Give your fan a try and keep an eye on temperature, I'd wager you will be alright.

 

well just figure out the rpm of the fan and it should match up to the rpm of the truck which is about 1,000 rpm or less..

 

huh? fan rpm has nothing to do with CFM rating of a fan. Well not between fan models anyway.

 

I'd agree on the switch part

you always want to have an over-ride if the thermostatic switch malfunctions

I had a 3-way switch wired into mine

Down was fully automatic; kicked on once the engine reached a certain temp, or when the AC was kicked on
Middle was over-ride off; completely disabled the e-fan
Up was over-ride on; just turned the fan on, regardless of engine temp or anything

worked good for when the AC was on and you were on the highway; no need to have the fan on if your doing 65mph







my fan was not a Taurus fan though; I spent a little money on my setup

 

You will need some sort of fan shroud, too. The more the rad is covered the better.

 

I had no shroud, and I never had any issues with mine at all

 

ditto, no fan shroud in the past year, not one problem.


and i also have the "trashy" toggle switch

 

that looks good now its just needs a label..

 

interesting.

 

ok so i figured a 4cy shouldnt heed a lot of airflow to cool so the fan i got is a 14" 1500cfm is that a mistake ?

 

first you had said it was 2000cfm not it's 1500cfm? and I would be willing to bet, that since it's an ebay dealy that that 1500 cfm is overrated too. A fan "upgrade" is not something I would be playing around with the cheapest bidder deal.

 

Setup the wiring and hook up the fan. Drive a bit and see if it is adequate for cooling or not. CFM won't mean anything if your wiring is too restrictive. Make sure you set up the wiring for a larger fan. Mine is set up for around 65 amp draw. I have an electric fan mounted to my radiator from a dodge avenger. It has been adequate cooling the 3.0. If I go up a long hill with it a loaded rig, I crank the heat, but I never have boilover or overheating. I used to get hot before I corrected the wiring. I have a mercury villager fan in the garage, but I haven't had the need to install it yet. I will probably do that when I fix my AC in the springtime.

My setup is for a 3.0. You should just install the fan and wiring, and relay(s), and drive. Worst case scenario, you'll notice the temp climbing slightly above normal and have to crank the heater.

 

Worst case you fry your freakin motor.
