adding a electric fan?

ok i have a 95 ranger with the stock 2.3 in it. i was wondering if it is possible to remove the fan that is turned by the motor and add a electric fan onto it. i just figured that this would be a good spot reduce some drag on the motor and give some more power to the truck.

my questions are:
1. is this possible, and if so where can i find a good electric fan to keep the truck cool? i live in texas and we get some pretty hot summers around here so i want it to stay cool.

2. what do i need to do to wire it up to either come on at a certain temp, or below a certain speed like 50mph and below it will be on and 50mph and above it will be off? i do not want to put a on/off switch on it because i might forget about it and that would not be good, nor do i want to wire it to switched ignition because i dont want it to be on when driving down the highway.

thanks RF for the input.

1. Yes it is very possible. Several people, including myself, have done it. Summit racing equipment carries many different types. Find one that fits on your radiator size wise and has a large CFM. Look around and the CFM rating for a stock fan can be found.
2. As for wiring there are fan switch relays that can be set to various temperature to turn the fan on and off as well has having a manual over ride switch.

like fddriver said the ones out of a taurus are one of the best, and if you go to a junkyard and find one you'll probably be able to get everything you need in one stop.

just so you know you're really not going to tell a difference by deleting the stock fan though. A properly working mechanical clutch displays minimal drag. The stock one is the most efficient for cooling and very reliable. Swaping to an electric isn't very hard, but it's really only worth it in very few situations. and i would not reccommend doing it in a very hot climate.

I wouldn't agree that is most efficient and it seemed to free up a little extra torque for me (although with a larger engine you probably won't notice).

I just got a taurus 2 speed fan from a junk yard for $15 and then the temp sensor and a relay. Wired it up so the sensor gets power when the engine is on, and then if the radiator gets to a certain temp then it flips the relay and turns the fan on.

seth556, have you noticed a increase in MPG? there are two reasons that i want to do this...
1. to get some more power from the little 2.3, without having to do anything to the motor.
2. to help with MPG.

i did the taurus efan search on this forum and it was really helpful. props to the person that figured that one out!!!

Here are my opinions on the e-fan:

1) E-fan offers minimal, if any at all, in performance increase over a mechanical fan/clutch that is working properly

2) Reliability is much worse with an e-fan, due to all the components:
a) electric motor
b) wiring, connectors, and fuses
c) controller (which includes relays)
d) temp sensors

3) E-fans do not have the cooling capacity of the mechanical fan/clutch assembly

And check out this R-F poll on E-fans:

How does the e-fan not have the same cooling capacity? Theres tons of different kinds of e-fans, I don't see how you can generalize and say they all don't have the same cooling capacity.

E-fans are limited to about 2K RPMs, and mave much less blade area than the mechanical fans. Matter of fact, the aftermarket e-fan companies do not recommend an e-fan for primary cooling with heavy towing applications:








And if that isn't enough, Rich (who is heavy into mods) has had cooling & AC problems with his E-fan, and UDP.....check out post #7 in this thread:

No one here does any heavy towing so I don't think that will be a problem.

Why do you always have to bring him up? Also this is a E-fan thread not an UDP thread.

E-fans work fine if you choose quality components and select the proper components for the application.

Agreed. There are more things that can go wrong but if you install it correctly the first time you will be fine.

The point to be made, you won't get the same cooling capacity with an e-fan as a mechanical fan/clutch

I think the e-fan poll tells the story about reliability of e-fans......


And this thread on e-fans is even a sticky:

Why did Ford put electric fans on the 3.8 Taurus's then?

Because it was a transverse engine.....

They could have figured out some ingenious device to keep it belt driven if e-fans were so unreliable.

Funny how you can go to a junk yard and 99.9% of e-fans in cars still work fine. The ones that don't have been damaged decause of a front end collision.

Just for your education, a diesel requires more cooling capacity!

Again, point to be made, an e-fan doesn't have the cooling capacity
that the mechanical fan/clutch has.......PERIOD!

Most of those are relay or control system problems. If you don't watch your temp gauge normally then you deserve an overheated engine.

Simply amazing!! I think I mentioned controller and/or relays as a couple parts that make e-fan systems far more unreliable than a mechanical
fan/clutch........

Yeah but this is coming from you. If someone other than you posted this info then I'd be concerned.
