Well I just finished introducing myself on the other topic and started looking into replacing the fan thats there right now with an electric one and came across this website http://www.creeperjeepers.org/Electric%20fan%20install%20in%20a%202.5L%20TJ.html I will probably be doing it within the next 2 weekends so ill post up pictures and how everything went. hope it helps.

Several of us are already running the FoMoCo fans. Some are using the Taurus while I'm running the even larger Lincoln MK VIII. I haven't even bothered setting up the HS circuit since the LS is plenty fast.

Out of curiosity, how much are you guys paying for these lincoln/taurus fans? The reason I ask is that you can get brand new 2950 cfm metal bladed permacool fans for around $120 and not have to worry about junkyard electronics.

AH! I hate this stupid middle-of-the-desert town! If I even find a working fan (taurus or lincoln mk VIII), it's $60+
Same story for pretty much everything else... ah...
There is one JY that may have a good (cheap) 136A alt from a ZJ, but I think it will require some modification of the lower bracket arm?
Just out of curiosity, does anyone know how big the stock XJ/ZJ 4.0, or ZJ v8 electric fan is? The shrouds on them aren't as square as the taurus or lincon (or so I've heard) and I imagine would be more fitting of my XJ.

car-part.com doesn't seem to be any good at locating fans, and the upull has none. So I grabbed one of the recommended Lincoln fans off ebay today. Just need to get a thermo control and relay for it.

Lincoln fan just showed up and I doubt that it will fit. Didn't realize how fat that fan package is.

The fan isn't 7" deep. You can shave off 1" from the lip to make it more snug as well.

I'll be taking a close look at it, but the fan is about 5.5" deep and that is almost exactly how much space there is between my radiator and crank pulley. One requirement I have with a fan is that I be able to drop the motor back enough to pull the transmission without having to take the fan off.
If it doesn't fit, I'll just get a Hi-perf perma cool like I had on the last jeep and use the lincoln fan for the 460 in my streetrod. They are only 3.75" deep.

Mine is not more than 3 or 4 inches deep (and I think it was more like 3, but I am in Argentina and cannot check at this time; be glad to check for you once I get back to Miami next week).

hey guys how are ya! Havent posted in awhile, but have checked the site a few times as this site is extremely helpful for us 4 bangers. You guys rock :thumb: Went to Hillz n Hollerz last weekend and for the most part was a blast. Good trails and lots of mud. One of the jeeps in the club got stuck in a creek bed sitting on a hornets nest with the sides off and back rolled up, needless to say the entire family felt the wrath of the angry :stick: . But anyways my point to this post i was at a spot on a hill where could have used a little more engine boost (one of the 6cylinder drivers made a comment of 4 pelicans and need some goose, or sumthn like that) and from the previous posts a electric fan would give more engine rev. This maybe what im looking for as i already have the performance chip, throttle body, and kn air intake. Found one of these on ebay and wandering if it would work

not to bring up an old post but figured we have enough threads about electric fans that i might as well add to one... anyways i went to the junk yard today with a friend and decided to get a electric fan from a Taurus... problem being i didn't do as much research as i should have / left the cheat sheet at home... so i ended up with a fan from a 94 Taurus with the 3.0l only to come home to see i wanted the 3.8l... the fan is a 2 speed and 15.5 inch fan. i am wondering if anyone knows if it will have enough flow.. couldn't fine any rating with a Google search (alot about the 1 for the 3.8l). but since from must of what i have read you guys are only using the low speed i would think that this one could work and at worst case have to use high...
long term i would like it to be able to cool a 4.3l v6. but would like to save a trip back to the yard to get the 3.8l fan.... or am i to lazy and i should just go back tomorrow?

I'm running a fan from a Lincoln MK VIII. I run it on the low setting only and it more than does it's job. I did manage to fry the temp. control module (most likely just the relay) over the last week or so. I may need to add a Freewheeling Diode to the circuit to protect it.
As for your problem. I don't think the 3.0l fan is the same part # and it may pull less cfm. I know the Lincoln fan I have sounds like a helicopter when it starts to wind up and it does pull a significant amount of air, even on low.
-
I did the same thing found a 3.0 fan its is a single speed and it will work you can hear it inside the jeep going down the road. BUT it will pull hard on your motor and alternator. I would upgrade to a 136amp alt. It fits real good and works great.
-
my 3.0l fan is from a 94 and was onyl used 94-95 and has 2 speeds, has 3 wires 1 black 1 brown and 1 yellow, it will pull less air but it doesn't sound like id need anymore flow. i think ill just go with it and see how it goes.. but should probably get my temp gauge working again (hasn't worked once since i pulled the motor to fix the slave cylinder), and a better alternator of curse.

(Decided to just add to this thread than start another :nod:)
I just got my Taurus fan a few days ago and it looks like it'll bolt right up. The only issue is that I'm not quite sure how to wire it correctly.
I read Jeffy's post in the FAQ but he only uses the low speed and no thermastat. I plan to run mine that way at first as well (until I upgrade my Alt.) but does anybody have a chart showing a thermastat controlling both speeds as well as what relays/guage wire/fuses are needed? :confused:
I can't wait to get started on this project and free up some power! :weee:
-
The thermostat would go on the power side of the harness between the fan and the relay. You don't need additional relays.
-
3.0 Probe Fan: Freebie
FK35: $150
Kill switch: $3

have the FK35 set to -22 deg and it sits rock solid 210 deg, never above

Well I tested my fan and it works great. Didn't test the Hi-Power but I'm sure it works too.
Jeffy, where is the ignition wire you spliced into? I'm having trouble finding it in the Haynes manual electrical schematics. Or did you just take apart the steering column and wire it to the ignition directly?

It's 3:24AM but the fan swap is all completed! :sleep:
I took the YJ for a drive around the block and WOW! That Taurus fan swap with the 4.0TB I just added a few days ago made one hell of an improvement on my low end torque! :dance:

You can get switched 12v under the hood off the relay socket near the battery tray. that relay is for the auto trans lockup. the socket is empty on manuals so its even easier...just plug a male terminal end into the right hole for switched 12v. this was the easiest source of switched 12v under the hood i could find after studying the fsm wiring diagrams for about half an hour.

pretty good tip :clap: - i guess you could also use a relay in there if you need more amps (never looked at it but now that you mentioned it i might use it for my electric fan)
-
I'll be adding a kill switch for the fan in the next few days for water crossings.
Here's a couple pics of the finished product.
Used a 60amp relay and 12guage wire for the power. Silver marked wire is spliced into the ingnition switch to activate fan.

Here's the engine bay now. Lots of extra room to work on stuff! That was alost worth it by itself. I bent some galvanized steel into L brackets to mount the fan to the radiator. It was a direct swap, just clamped it where I wanted it and screwed it on.
(http://i6.photobucket.com/albums/y211/kavick/Jeep%20Build/DSCN8451.jpg)

I would advise to get some wire covers for the wires. They can prevent the wire from shaffing and shorting out... Plus, it just looks neater!

Is the shroud needed after the swap?
With it i imagine the temp would be lower?

You still need a shroud, but not the stock one. I used the Ford one in mine. As for the temp, it should actually be the same (around 200~210*), but it will not go higher as can happen with the mechanical fan when at slow speeds.
-

The FoMoCo fans all have their own shroud. That's what's holding the fan in place. You do not need to reuse the stock shroud as it does nothing.

It's only on the 3.8L engine and looks very distinct:

if you have 117 amp you don't need to upgrade - you can use either a temp switch (sender) combined with a relay to power the fan or you can use a switch (and it is recommended that you use a relay in this case as well but if your switch has enough amp rating to cover the amp draw of the fan you can get away w/o a relay, but again it is recommneded that you use one).

Running high amp's though a dash mounted switch is a good way to cause a vehicle fire. Do it right the first time and use a relay. Not so much, because of the switch but the wiring. It can get warn, cut, etc and then you have it sparking up.

How many amps does the fan draw. Where do I buy and what temp switch should I get?
What amp relay? Where do I mount the temp switch?
Is there a post that shows how to wire it?
Do I just unbolt the fan and leave the pulley?
I guess just hold my hand thru it :biggrin:
-
What does a relay do?
i missed this question in my first reply
a relay will close a circuit between 2 of its terminals based on a command given to another set of terminals. so to put it in plain english, when your temp switch reaches a certain temperature and closes it's internal circuit will give a ground to it's connector terminal - that ground will be used to close the relay circuit which in turn will power the fan - this is because the temp switch for example could have a rating of 1 amp for its internal contacts and your fan can draw 25 amps - that means if you wire the fan thru the temp switch directly it will destroy the internal contacts - by using the relay you isolate the high current (amperage) thru the relay only, and the temp switch load will only be used to activate the relay solenoid. the temp switch is also known as an electrical thermostat or bimetallic electrical thermostat (not to be confused with the water thermostat that goes before the radiator, that is a mechanical device). There are also adjustable devices that use a temp probe an in that case you can adjust the temperature at which the fan turns on (more specifically at which the command circuit will close) - you can buy one of those and they usually come with a relay wired in, so it could be easier to install but make sure that the relay amp rating covers (is at least) the amp draw of your fan. The temp switches have a set on and off temperature. There is also a company that makes an electronic device which controls the speed of the fan based on the temperature - some guys here have used their product with excellent results (i have not used one personally) - the name of the company is Delta Current Control.
The idea of using a relay is the same for the manual switch (which is used instead of the temp switch).
Since you asked what is a relay I suggest you ask for some hands-on help with this one and don't attempt to do it on your own - you will also need to have matching wiring (that will be rated to support the current drawn by your fan), matching fuse for the power terminals of the relay and if you are not using a fused connection for the solenoid of portion of the wiring (command terminals) you will need a fuse there too.
Like Jeffy said, last thing you want is an electrical melt or fire, so the first time you attempt this you should do it with the help of someone that has experience with automotive electrical wiring.

From what I've read the fans pulls 26-30A on the low speed and 33-43A on the high speed. Initial start up has a peak draw of around 100A from what I've heard. Low speed, is fine for the 2.5L.

Don't run it on the HI-speed circuit. SPAL has even gone as far to say not to use it at all. Although as long as you stay in low-speed, it should be OK.
Speaking of, have you seen the new Delta controller? It's designed for teh 2-speed FoMoCo's and is cheaper then the other units. http://www.dccontrol.com/fancontrol.htm
-
DcControl makes some great products. Turn-around time is pretty long but for me it was worth the wait. I run the variable controller which pulls very few amps, only enough needed to cool the engine. There is no high draw at initial start of the fan either.
-
It seems that the new controller basically has two speeds only; I have their FK35 IIRC, and I am VERY happy with their product, as not only does it control the speed (by the way, it is connected to the high-speed side of the fan), but it also (1) allow for soft starts (increases the speed gradually instead of full-on) which reduced amp draw, and (2) allows me to connect the slow speed side of the fan through a relay as a back up in case the controller should ever fail (almost 3 years and no issues so far, but I prefer redundancy on a Jeep if I am to take it on a trail to the middle of nowhere!).
Like Bounty mentioned, turn around time is a bit long, but well worth the wait.

Is the fan suppose to blow towards the radiator or pull from it?
The Ford Taurus fan I found is only a single speed.
Will that be OK?
I got a Ford Escort fan, it pulls instead of blow.
but it's a 2 speed.
Thanks,
Vance
-
A single speed Taurus fan is from the smaller engined car. It might work but really, if you're going to go through the trouble then you might as well do it right. Especially, if the fans cost the same. It needs to be from a 3.8L and only the 3.8L. You can check the Sable as well. The fan will be a puller.
-
Get the 2spd from the 3.8L Fords, the shroud fits the Wrangler radiators perfectly. They are all puller fans, not many OEM pushers out there.

a puller will be installed between the rad and the motor (on the motor side of the rad). a pusher will need to be installed in front of the rad behind the grill - the reason is to not fight the natural airflow you have when the vehicle is moving (as well as not pulling/pushing the hot air from the engine bay but that is a the secondary reason for not doing this) - so keep in mind that the airflow (natural or forced using the e-fan or stock fan) _needs_ to be
1. thru the grill, thru the rad, and thru the fan shroud (with a puller fan)
or
2. thru the grill, thru the fan and fan shroud, and thru the rad (with a pusher fan)

Delta Current Control has a new controller out specifically for the Ford two speed fans. Its called the 2SP, has two 60 amp relays and sells for $69.95.

by the looks of the pic in there it seems that it includes also the wiring harness and the temp sensor so that is a great price

The only thing it lacks is the PWM which is Pulse-Wave Modulation. That's what gives the variable speed of the fan. Still, for most people, that won't matter as all they want is the fan to turn on and off. The PWM is jsut a added plus. Wish they could lower the cost a bit though. Seems the only two major players are SPAL and Delta.

If I understand you correctly, you are trying to wire your fan up so that the low speed is setup like the diagram, but with the option of turning on the high speed manually with the other position on your switch.
If that is what you are trying to do, you need to have a second relay activated by the switch allowing current to flow from the battery through the relay to the high speed wire for the fan. The power should not be going from the battery through the switch to the fan. Wire the second relay the same as the diagram, but with out the thermostat. The #86 on the relay will just go to ground. Provided you have wired your switch correctly, when you flip your switch from the low speed position to the high speed position the low speed will be de-activated and in the off position both are off.

I have the switched power (in the diagram) going into an on off on toggle switch.
Everything else I have wired just like the diagram.
I have the power going from the toggle switch to the fan.
I want to use another relay so I don't overload the toggle switch.
How do I wire the relay in?
before or after the toggle switch?
Thanks,
Vance
if you wired everything like the diagram i would guess (but still confused by the conflicting statements you made) that you have a relay already in. If you are not planning to use a thermostat then put your switch in the same place as the thermostat in the diagram, keep everything else the same and that is how you integrate the relay (the one that is pictured there is the only one you need - the terminals on the relay are labeled so you can't go wrong). the switched 12v with a 1A fuse is low current so that's how you isolate the high current (amperage) circuit going to the fan, you don't need a second relay. If you want to have both a switch and a thermostat _DO_NOT_ put them in series (you said you put the switch on the 12v switched - the 12v switched means is from the ignition, so you only have power when your key is in RUN position) - you can have the switch in parallel with the thermostat if you want to override it (so you can turn it on earlier or if your thermostat fails). If i were you i would stick with that diagram, it is the way you should wire your fan anyway and you can enhance it later once you got this figured out.
It would help though if you draw what you meant so we can see how you wired your fan, it's pretty hard to understand based on your explanation - as you can see neither St.Chevrolet nor I could figure out for sure what you meant - so draw a diagram and take some pics (you could also take pics of your istalled fan and wiring, that would help too).

Sharpxmen for some reason your quote does not show all of my reply. And for some reason, I'm not sure why, I thought we were discussing a 2 speed Taurus fan not a single speed, my bad.

If I understand you correctly, you are trying to wire your fan up so that the low speed is setup like the diagram, but with the option of turning on the high speed manually with the other position on your switch.
If that is what you are trying to do, you need to have a second relay activated by the switch allowing current to flow from the battery through the relay to the high speed wire for the fan. The power should not be going from the battery through the switch to the fan. Wire the second relay the same as the diagram, but with out the thermostat. The #86 on the relay will just go to ground. Provided you have wired your switch correctly, when you flip your switch from the low speed position to the high speed position the low speed will be de-activated and in the off position both are off.
Yes it is a 2 speed Taurus fan and I want to have a thermostat to turn the low on and a manual toggle switch for the high speed
and also have the toggle to turn it off completely.
Do I dare ask about having a light come on when the fan is on (both low and high)

I understood your reply, didn't understand what he (haulincats) meant - your guess was better than mine, he was referring to the 2 speed Taurus.

I assume you want something like this. I considered that the "low speed" lead and "high speed" lead are both supposed to be connected to "+12v" and not at the same time (someone who has a taurus 2 speed please confirm, i don't have one - also please confirm whether the 2 can or cannot be connected at the same time, to be on the safe side i considered that they cannot which makes more sense to me if the change in speed is not an "in series" resistive load)
(http://i57.photobucket.com/albums/g222/sharpxmen/Misc/EfanInstall_Dual_Speed.jpg)
also make sure the Main Fuse and the relays are rated for the current draw of the fan motor (I think Jeffy posted the amps for it in this thread, i was too lazy to look).
toggle switches: the first one on the low speed can be on(auto)/off, the second one would be high speed override (will be on high speed regardless whether the first switch is off or on and the thermostat can be also on or off - always high speed, it will automatically disconnect the low speed circuit when the relay switches to high speed)
those splice points labeled with A means you will have to feed the solenoid of the second relay with the same 12v switched source as the first relay (low speed) but from behind the fuse, you don't need a second fuse, same for the fan high current circuit, you only need 1 fuse (but that matches the amp requirement for the fan). the Relays need to be matched as well, the high speed one has to be at least the amps that the motor is rated at for high speed, the low speed relay has to match the amps that the motor is rated at for low speed (but it can be the same as for high speed if you want to keep it simple).
there is another solution for this - you can use an on-off-on switch and have the 2 relays in parallel rather than in series, the first "on" position would be in series with the thermostat, the off will keep both speeds off and the other "on" will activate the high speed relay - if i find time i'll post a diagram on that too
-
or like this (this is using a 3 position switch on-off-on) - i made the same assumptions here as for the other diagram (the high speed and low speed leads are both 12v and cannot be connected at the same time) - please verify this first
(http://i57.photobucket.com/albums/g222/sharpxmen/Misc/EfanInstall_Dual_Speed_2b.jpg)
you can also have the switch (EDIT: the on-off-on switch) connected on the +12v side as an alternative right after the 1A fuse and have the 2 connections going to pins 86 on the relays and connect the ends on the other side to ground - same with the thermostat, can be on the other side of the solenoid connected to pin 85.
let me know if you have any questions

here's version#3 with the 3 position switch on the +12v 1A side

I have the 2 speed Taurus fan in my YJ with a on-off-on rocker switch. I have the switched 12v+ (comes on with ignition) supplying the power to the on-off-on switch. The low speed position of the switch activates a relay which allows current to flow from the battery to my DCC controller which is connected to the low speed wire of the fan. The high speed position of the switch activates a heavier amperage relay which again, allows current to flow from the battery but to the high speed wire of the fan. When I switch from low to high the DCC controller is de-activated and the opposite happens when going from high to low. In the off position obviously the fan is off.

Sharpxmen if your drawing is showing the dcc controller ground and the high speed relay ground together you are correct.
Haulincats for real nice good quality switches (labeled) with the light you are looking for go here: www.otrattw.com
jfrabat can vouch for the quality of the switches.

Sharpxmen if your drawing is showing the dcc controller ground and the high speed relay ground together you are correct.
yep, affirmative.

Man you guys are great !!!!!!!!!!!!! to be able to help out a dummy like me, Thanks.
Just one more ? ( I think just one more )
I already bought the relays and they are 5 pin, the 5th pin is 87 A
Can I still use them?
Thanks,
Vance

It would be nice if these wiring diagrams could end up in the FAQ's :whistle:
Great job guy's!

yes, you can use them
87a is the one that is not connected and in the first dual relay diagram i posted was only connected on the high speed relay. It is normally closed (the contacts are connected between terminals 87a and 30) so basically when you activate the relay it would disconnect 87a and 87 would be connected to pin 30.
EDIT: one thing that i did not answer or put in the diagrams was the monitoring lights - you can connect a light bulb between pin 87 on each relay and ground (one wire from the light bulb goes to pin 87 and the other one is connected to ground) - that way whenever a relay is activated (on) it will light up the corresponding bulb.

Can I use just 1 light?
-
Haulincats here is a good site to learn about relays: www.bcae1.com/relays.htm#demo
-
Can I use just 1 light?
yep, take your pick - 0, 1 or 2 lights - between pin 87 and ground - basically whenever terminal 87 will get 12v the light will turn on at the same time with the fan for the corresponding speed. If you only want it on low speed for example just connect the light like i said but only on the low speed relay

I found a Taurus fan for $35 on E-bay. It is a two speed.... I hooked it up (low speed) to a manual on / off switch. I had the temp probe hooked up initially and it went bad and I overheated. To fix it I just hardwired it to the battery to get me home.
Was out at Ocatillo Wells last weekend. 70 degrees outside....runnin hard....but it still didn't get hot enough to turn it on......so no need, so far, for the high speed....low should be fine. I turn it on when my gauge reads 200 degrees. That is what it used to max out at, with the stock engine fan. The temp drops very quickly when I turn it on, and it maintains the temp at arount 180 degrees.
I love it. Follow Jeffy's write-ups and you can't go wrong.

Actually I don't have enough idea on how to install an electric fan. But thank you for the link you have gave because I found out the exact way ob how to install it. Electric fans can be a less expensive and more Earth-friendly alternative to supplement or even replace air conditioning, provided you use them properly.

i think lauretta07 is talking about a ceiling fan, i don't think she's referring to a 15mpg [on a good day] Jeep as Earth-friendly :lol:
that's a good score on the 2 speed Taurus, they seem to be hard to find lately :thumb:

for some reason i could not find a good one here when i looked (found a couple but they were both accident damage in front) - that's why i end up with the lincoln one.
