Detailed E-Fan Install

[xtrememeasures10]

Alright so i finally bought my E-Fan Today. I got a 14" TorqFlow fan from autozone. The part number is 733690. It draws 11.5 amps and puts out 1250CFM. I would have got a fan at a junk yard but Im up there all the time so they cut me good deals all the time. Then i got a Preset Electric Fan Control Module. Its preset at on at 185F and off at 170F.

I know this fan doesnt put out as many CFM's as the taurus fan. But the guy there looked in TorqFow's application book for a 2.2L w/ ac and this is the fan it recommends.

I have read a lot about the install on here and theres tons of questions people always have. Mostly in the wiring. Theres tons of pics of the hardware install but none of the wiring. Im going to try and clear some of these questions up to the best of my ability. Tomorrow ill be beginning the wiring install and im going to wait on the fan install until i make a bracket at work to mount the fan to.

I want to try and make this as detailed as possible to maybe reduce the number of efan threads popping up here. I am open to suggestions about it so dont be shy. So heres some pics of what i have to start with.

[jesse6]

awesome dude, thanks!

[S-10Driver]

i hope it flows enough to keep it cool. probably should have at least went with the 16" version.

[suicidal]

how much did this fan cost you?

its what the company recommends. But i might see what kinda deal they can work w/ the 16" one just so i have that extra cooling on those really hot days.

[n8rsk8r]

hey post up the wire bundle part number also! That thing is money!! Oh and how much for that?

[xtrememeasures10]

Wire bundle part number 733652. It is also made by torqflo.
I thought i put that in my first post but i guess not!

Well im trying to figure out how many cfm's the 16" model puts out cause i might swap the 14 for the 16. Even though the manufacturer of the fan recommends the 14 i would rather my truck have more air to cool on hot summer days.

Ok just got off the phone w/ autozone. the 16" model only puts out 1400cfm's. and the stock fan is about 16" as well. and the 16" fan is 5 bones cheaper so im gonna go get it.

[n8rsk8r]

Hell yeah man! I REALLY interested in this, cause I may do this instead of the Taurus fan Keep us posted!!!! Total cost was???

[JaR3d]

if you could possibly explain (in detail if possible) how you went about with the wiring. That would be awesome dude! good looks

[xtrememeasures10]

Alright I had to help my buddy get a washer and dryer to his place now im back home ready to do the electrical install. Pics step by step once im finished!

Like i said im going to try to be as detailed as possible. This harness looks like its going to be a breeze to install.

.

Right on. yeah the normal cost of the 16" fan is 64.99. Like i said i got a good discount and now i got it for 30 so. 30 plus the harness at 24.99. I needed some heat shrink and i bought a bunch for like 5 bucks. I already have soldering iron, solder, flux so im ready to go. but you can get a soldering iron at the parts store for like 10 bucks probably.

thanks dude, the only real problem i ever got stuck with was when i tried to find a 12v ignition without constantly frying wires, i gotta admit, i am horrible at wiring. do what you gotta do and git r done

[Chris0nllyn]

hate to tell you but that fan wont work...i had the same one, it couldnt keep my truck cool

run a wire from the t-stat relay to the fuses box...theres a spot for 12v aux...bam, theres your switched 12v

Im not wiring mine to the ignition switch. Since this one will only come on when the temp switch senses that the truck is too hot. Kinda like how a honda is wired. The fans will stay on to cool the car after you shut the car off, but will only run for a min or so. and since its only a 16amp draw fan it wont drain the battery too much running for a min or so after the car shuts off.

See i was hoping someone had gotten this fan before to give an insight. Did you do that 95 taurus fan instead?

[xtrememeasures10]

ID the wires so i wouldnt be like wtf when i got out to my truck.

[xtrememeasures10]

F it this think is pissing me off. it wont let me upload fotos. ill try tomorrow hen im not drunks as hell

[n8rsk8r]

Could you post up a pic of the wiring diagram also man? That would be pimp if you could! Good luck man! Hope it works for you!

yep, taurus fan ftw

[xtrememeasures10]

So i emailed the manufacturer today this message

"I purchased your 16" Fan from autozone for my 97 s10 pickup 2.2L motor 2X4 w/ a/c. And i have heard on a forum that someone else installed it and it didnt cool enough to keep the truck from overheating. I was wanting to make sure this was the correct fan for my vehicle thank you!"


And this is the response.

"There are several possible problems that can be encountered when of an OE Fan/thermal clutch assembly.
First is the amount of air flow that is necessary to cool a particular engine. That determination should be computed first.
The amount of air flow of the replacement fan is spec'd as a specific flow thru a typical radiator. A typical radiator is considered to be 1 in thick. Adding additional cooling efficiency by increasing radiator thickness may actually restrict air flow when using an electric fan.
Our 16" fan operates at app. 1150 CFM (16-17amps)across a typical rad or or app. 1350 CFM
The amount of current (amps) necessary to operate the fan @ a given amount of air flow is another consideration. Normally, a fan will require app. 16-18 amps to operate at max speed. These must be 'free' amps. This can be determined by operation of the vehicle with all electrical draws operational. Engine idle, all lights on, a/c on, wipers on, blower on high...etc. Load the system down completely. Measure the amount of amps being produced when these drains are evident. If less than 20 amps the fan will not operate at max efficiency.
Consider the possible heating problems that may exist within the engine cooling system. An electric fan, or any other fan will not overcome a possible engine cooling system problem.
Vehicles with A/C may require more than one fan to properly cool the radiator (engine) and condenser.
Of course proper installation is always required for proper operation.
It is possible that the best cooling will occur with the standard OE fan/clutch assembly. The use of an additional fan may provide additional engine cooling.
First considerations would be determination of engine heating problems and a evaluation of OE Fan/Clutch assembly. Determine is sufficient alternator output is available for proper fan operation. This is key and should be a major determining factor for installation of electric fans.
Thank your for your support of CWI/TorQueFlo and Autozone products."




Is it just me or did i not receive an answer to my question. lol. I got blah blah blah amps, blah blah blah Cfms blah blah blah. They have to have had someone ask about this in the past or had a customer w/ a problem w/ it. Oh well well see.

I figured out a way to mount the fan when i was at work today. still havent finished the electrical install. Im going to mount the fan to the OEM shroud inside the shroud in almost the exact spot the OEM fan is located. I just have to yank a couple things from work this week.

[Chris0nllyn]

make sure you switch the blade so its a puller fan...if i remember right my fan came out the package as a pusher

[xtrememeasures10]

Yeah this one came out as a puller. Im having problems w/ this harness. the fuse keeps blowing and i know for a fact that i have no shorts b/t the relay and the motor where the fuse is located so i might have a bad motor. I swapped in a 30amp fuse and watched it carefully. My fan is not auto turning on when the engine reaches operating temperature but it does when i turn the ac on. Tomorrow im going to get the stuff to make the bracket to put it in the shroud.

Did you mount yours directly against the radiator?

[xtrememeasures10]

Alright well i think i got all the kinks worked out of the harness.

Here goes the electrical install.


Wiring harness w/ wired tagged according to schematic.

mounting location for temp sensor.




Foam Padding added.


Retainer clip for sensor.


Sensor two pads and clip installed.


Removing back of shroud to drill hole for wires to go through to the sensor.


Hole drilled for wire to come though.


Power wire going from battery to sensor then out of the sensor to the relay to engage the relay.


Wire coming out from sensor through panel. temp mounting location for relay.

[xtrememeasures10]

disconnecting ac clutch engage wiring.


Wire cut and stripped ready to be tinned and soldered.


Shitty soldering job. I didnt have flux. I came back the next day and re soldered and heat shrinked it.
Harness came w/ same color wire kinda a greenish blue color.



Heat shrunk and ready to have a longer wire spliced into it to go to the relay.


All protected back up.


Pretty obvious ground wire off relay harness and ground location.


extra length of wire spliced in. Make sure you splice in a extra foot or so that way if you have to change your head gasket or something you can cut zip ties and move it out of the way. I just used some extra wire i had, color of the wire doesnt matter as long as you dont get confused wiring it up.

IMPORTANT!!! the blue green wire that comes w/ the harness has a diode soldered and heat shrinked into it. YOU MUST USE this wire if you dont your ac will always turn on. The wire also must be installed correctly so the polarity of the diode is not reversed. If its reversed the fan will not turn on when the ac is turned on. The end of the wire that comes bare wire must be the one thats spliced into the ac control wire.


Again used snake skin to protect the wire, zip tied it to support it around. this is just a temp location im going to move it after everything is all working well. I just want easy access in case i need to work out a problem.


Ground inplace for relay.


Hook harness into relay.


Red main power wire for input to relay then power will travel through relay into orange wire to the fan.
Yellow wire power input for sensor in radiator core.

NOT SHOWN YET. The orange wire off the relay harness has a fuse then goes to the fan. then run a black wire from the fan to a ground and your all done w/ wiring. I have pics of that install once the fan is installed.


And a teaser. Im going to bolt L shaped brackets on the inside of the fan shroud. Then rivet nut plates to the backside of the L bracket and a bolt through the mount on the fan will hold the fan in place. I still need to get some more hardware from work. Hopefully ill have this done by the weekend since im going out of town. I would like to see and increase in gas mileage for the trip.

[Chris0nllyn]

good luck with that sensor...mine never kicked the fan on at the right temp...try grounding the relay to the frame...

[xtrememeasures10]

Hmm well see dude. maybe ill get lucky for once. If not what sort of temp sensor did you use?
I have a grounding jumper on the lower part of my core support to the frame from when i installed my fogs and hids so im getting a good ground on the core support too. but yeah for other ppl that would be a really good suggestion.

[wip_customs]

FINALLY i been wanting to do this just a little weary thanks for the writeup

well you might want to wait until its completely done so you can be for sure all my hard work is going to pay off ya know.

If not i will modify it and make the sob work

[Chris0nllyn]

i used a thread-in type sensor from derale...works great, and its adjustable

[xtrememeasures10]

and where is it threaded in? pics?

[xtrememeasures10]

alright long due for an update

I decided to get a taurus fan. Going to the junk yard tomorrow after work to pull one.
Anyways i havent updated cause i went on vacation, tree branch fell on my truck when i was out of town, didnt damage it thank god. Anyways tomorrow ill be getting the efan and maybe putting it in depending on whether or not i have to modify the wiring setup for a dual fan. If i do ill have a new diagram and start from scratch with the wiring. I promise im gonna make a good how to here. Its just time and money right now are hard to come by.

Anyways what year taurus efan fits best????

[freddy1.0]

Xtreme,

This is the fan, comes on taurus, lincoln (mainly on Mark VII), and mercury sables, The engine your searching for are 3.8L. If you find yourself having to choose pick the earliest year. And Chris is right these things are way more powerful, I'm talking 4000-4500 cfm on full load. There is a 700+hp mustang out there that this thing cools.

And this is the relay Chris was talking about for derale..

http://store.summitracing.com/partdetail.asp?autofilter=1&part=DER%2D16739&N=700 +115&autoview=sku

I found this one on eBay, it comes with a 30 amp circuit breaker. Comes in handy if you don't mined spending on fuses all the time!

http://cgi.ebay.com/ebaymotors/FAN-C...spagenameZWDVW

I haven't done it yet, but I and the rest of the crowd are eagerly looking on, so get to it!

[S-10Driver]

where do you thread that screw-in stat into?

[BudRacing]

For a 2.2, the taurus fan is overkill IMO. Just about any fan from a FWD car will work if it fits. The taurus fans are pigs anyway. I got a fan from an Aurora to replace a POS permacool (I went through two of those). Even with it hooked straight up to ONE 30A relay it hasn't fried it yet and it cools my 4.3 with the AC on in traffic.
The Aurora is a FWD v8 car with no grille and two radiator fans. However, the fans come out separately and I took the fan with more blades on it--which I'm thinking may be the low speed fan. Anyway, I paid $13 for it and wish I'd gone that route from the beginning.

i tee'd off the coolant temp sensor...you can kinda see it in this pic, its the brass piece coming off the t-stat housing

[xtrememeasures10]

Well damn I got there and saw 2 different types of fans. a single one w/ a shroud and a dual setup. All the wiring harnesses and shit i always remembered 2 relays so i figured two fans. Called nick z he said he wasnt sure but thought it was 2 fans and another guy from the forum and they said they thought the same thing. So i have the dual fan setup. Am i gonna need to go get the single fan dual speed setup? I figure 2 fans will work just as well.

[xtrememeasures10]

Dual fan setup isnt going to fit. TOO big. It might work if i put one fan in front and one in back of the rad. but i think ill just go back monday and get the single dual speed fan. damn it i was ready to set it up.

[freddy1.0]

S-10driver, you can use this or make a T-fitting like chris, his is probably the cheaper way to go.

http://store.summitracing.com/partde...5&autoview=sku

My thing with taurus fans are the junkers are going to charge me the same no matter what car it comes from, so why not get the most bang for your buck? Any fan that cooled a engine with a larger displacement then a 2.2, would probably just do fine.

Well thats somewhat true. But your cooling the aintfreeze in the radiator. With the fan your more worried about the size of the radiator it has to cool.

Btw that t fitting would be perfect. Imma go that route if my sensor setup doesnt work.

[AVTekk]

ya you need the single fan setup, the dual is way too big. also the taurus fan draws like 50amps, youll need a new heavy duty relay. i learned that the hard way on my first install.

[Chris0nllyn]

i have my fan hooked up just to the low speed...cools my truck fine...and i havent blown any fuses or burnt up any relays

[S-10Driver]

the low sp of the taurus fan draws right at 30A at startup and runs around 11A constant speed from what i've read.

the high sp of the fan draw upwards to 90-100A at startup and runs over 30A constant i believe.

JEEzz 100amps???? good lord.

Hmm i got it working on the low speed but i forgot my crescent wrench to take my old fan off at work today..... I have had a long week and its beginning all over again. Im just happy the junk yard swapped out the fan for me no hassles. I also got an extra upper shroud so that way i can work out any kinks and still have my old shroud. It was a 4.3 shroud tho so i had to section it w/ a cutting wheel. Well i worked on it for a while today and had nothing but problems. Im exhausted ill mess with it tomorrow. I think i might have to get a relay harness w/ much thicker gauge wire.

Yeah i took the dual back today. It was HUGE! lol I could have probably fit one in front and one in back but why bother when the single design works just as well. Yeah i think thats why it wasnt engaging. I think the relay just cant handle the amp draw. I already directly connected the fan to the battery to verify the fan is working.

all this talk about problems makes me dread doing it.

There are other e-fan threads that don't have problems.

my install went smooth....except fot the fact that the junkyard gave me a bad fan at first...but i got it exchanged no problem

[xtrememeasures10]

Alright I had a bad relay. I got it all wired up and working. Only thing is the sensor turns on the fan at too high of a temperature. Tomorrow im going to go get an adjustable sensor. Ill have some pics tomorrow. I kinda rushed to get it done tonight. The fan kicks on as soon as the ac compressor is turned on. and keeps it really cool. It actually isnt a slug when the ac is on too!!!!! cant wait to see the gas mileage gains. How many mpgs should i expect to see?

[BudRacing]

The compressor really isn't the best place to have the fan wired. The high pressure switch on the backside of the compressor is ideal. When you have the fan wired to the clutch switch, then the fan turns on and off with the clutch. Once the system has a high pressure the clutch begins to cycle to maintain that pressure. Now, once your system is under pressure your fan is going to be constantly switched on and off and will potentially kill your relay pretty quickly with all of those high amperage off/on cycles. The high pressure switch on the back keeps the fan on as long as there is enough pressure in the system, which is ideally when you want the fan to be on.

[xtrememeasures10]

Alright I wanted the low speed fan to run for like a min once the truck shut off. But i am going to need a timer circuit for that. For now Im pulling the fuse lol. Where is a switched ignition source under the hood?
