Ford Taurus fan..

[J B]

Or do what I did....I used the bottom portion of my factory ZJ shroud...trimmed everything to kinda half-ass match up....then I used some fiberglass to mate the factory shroud (what was left of it anyway) with the taurus shroud. I filled in the HUGE gaps with triple expanding foam and trimmed the foam, in an effort to "create" a surface for the fiberglass to lay on, since the gaps are huge.

In the end, I left the foam in place, trimming it out of the way for airflow on the radiator side. It sticks really well and adds to the structural integrity of putting the to shrouds together.

Using this method, the fan "drops in" since the bottom of the assembly is the factory shroud. Then you just rig up a way to hold it in from the top and wire it up.

Also, I only run mine on high speed, since that's where I need it most of the time. I'm also piggybacking a big relay from a Hayden electric fan controller, as other have mentioned.

guess i shouldnt have opened my mouth....


the zip ties on my fan just broke and my fan fell on to the motor pulleys....



didnt mess it up tho... caught it in time... got the stuff to do it the right way so i can do it tomarrow...

[jsteves]

or use a 5.9 fan...bolts right in. mine too is wired with a 3 way switch. i used a relay and temp sensor to automatically run the low side. and a ford starter solenoid to run the high side via the switch which includes an off position of course.

Yeah, but the 5.9 fan is $$$, and Taurus fans are a dime a dozen.

And beware - the Ford starter solenoid isn't meant for continuous duty and it WILL fail. I have tried using them in applications like this before, and I always had to keep a spare, because they didn't ever last very long.

The $35 or so for the Bosch relay is worth it.

question: a friend of mine had a taurus fan in his TJ and when he would turn it on high it would suck itself into his radiator and chew it up, has anyone even herd of this b4?

never heard of it, but it sounds like the bushings in the fan motor were toast, or that the fan blade itself had some play on the motor shaft and could move around a bit.

Can somebody tell me what exactly I need to get so I can put this fan on my jeep!!!!
I know I need the fan wires,relays ect...but what sizes wires,relays ect....
How do you make it run so it takes care of its self with teromsat
I hate cluch fans they suck!!!!!!!!!!!!!!!
THANKS!!!!!!!!!!!!!!!!

Did you even bother to read through this thread?
All the information is there, don't expect to be spoon fed.

slight fix and that quote is sig worthy!

i must have f d somthing up when i did mine the fan was drawing way way to many amps i belive . ( never checked how many amps fan was drawing, couldnt find my amp clamp ) it was a pita was drawing hard on my stock alternator . and left me with a dead altnator the other day .. i want an efan but just couldnt wokr out why it drew so much power . do i need to replace the altnator.

Here's a thinker for everybody - running a Taurus fan with a 35 amp DC Control box. In-town with the AC, shitty dash gauge reads 210, nothing more. In my setup, when the AC is on, the fan is getting the full 35A from the box.

On the highway though, temps hold 1 tick above 210 (AC on). Is the Taurus fan running at 35A (full bore that I can hit it with) being counter-productive? AFAIK, there's no clutch to the Ford fan that cuts it out when more air is being pushed at it than it can pull.

Bottom line: Should I wire a cutoff switch into the cab so I can kill the fan when on the freeway (65+ mph)?

I'm thinking one of these buggers:

[TrojanMan]

I have a switch on mine but never turn it off.

[fpkites]

So maybe my issue is a dirty condenser/rad then - I'll hit it with the shop air and water hose this weekend and see what happens.

MY Jeep has always run hot on the highway after I lifted it and added a front bumper, big tires, etc. Unless it starts getting close to 260* I don't worry about it.

This was with the stock fan, a 99 WJ fan and the Taurus fan, so it's not a fan issue for sure.

What continuous duty 40-50amp relay can I grab from the junk yard?

Does anyone know if I could grab said relay from a fuel pump or maybe AC? All the relays I've seen are the plug-kind that wouldn't mount easily.

I can get relays for dirt cheap at the yard- I'm trying to avoid the $30 Bosch new. I grabbed a Ford starter relay today- but after reading this thread, I think I'll forgo the starter variety relays and look for a 100% duty one.

Any thoughts?

For wire size check out this chart: Looks like 5-6 gauge would be ideal for MAX power transmission. On the other hand, you could get away with 12 gauge wiring and probably not melt it.

10 gauge is fine. That is what is stock on the Taurus.

fpkites helped me install my taurus fan a few weeks back w/the DCControl modulator box. Does anyone know which wire going into the A/C Compressor I need to connect my blue wire to? Apparently my wires have a different color scheme then his did...thanks!

What year and motor?

[fpkites]

His is a 98 with the 5.2. Wire colors at the compressor were not colored as obvious as mine.

Thanks! I guess that is good info to know!

It's the dark blue/yellow wire in case anyone encounters the same issue. I got the rest of it wired up today! >

vv ccfcfvvxI actually installed the fan last spring but didn't take any pics at the time. I originally had it setup to manually but recently bought a Hayden controller setup and wired it in. Since it was apart at the time I took some pics.

For the physical install I actually bolted the Taurus into the stock V8 shroud using self tapping screws. The bottom of the shroud opening needed to be opened up a bit but not much. Doing it this way allows me to simply drop the fan assembly back into the stock mounting points, no custom fabbing needed. Also its super fast to pull the fan for repairs(belt replacement, etc) or to hose out the rad at the car wash, just pull the two 10mm nuts holding the shroud on.







The hole was drilled with a hole saw to allow the stock plug to pass thru. I kept as much of the original wiring as possible.

Including the fuse and holder. I'm running a 40amp fuse. You can see it in the pic bolted to the battery hold down bolt.



Sorry thats it for pics. I'll do a quick writeup of the wiring.

Getting a relay that can handle that much power is essential. I've seen lots of people have trouble on the trail because they used a 30amp Bosch relay like for offroad lights. Its no big enough for the Taurus fan. The easiest to find is a selonoid like for a starter, but it must but rated for continous duty, similar to the ones used for winches or dual battery setups. They are easiest to find in the RV section of most autopart stores.

The setup is controlled by a 3 way switch on the center console next to the shifter. Off is center, up is on(override), and down is automatic.

The Hayden controller is powered by the 3 way switch when in automatic. It has of the type that has a probe in the fins on the rad. When the preset temp is reached it triggers the solenoid for the fan. It also has an auxiliary wire tied into the AC clutch wire to activate it when the AC pump is engaged.

The other wire from the 3way switch goes directly to the selonoid and activates it regardless of waht the Hayden controller is doing, no power actually goes to the conroller in this position.

When the 3 way switch is in the off position no power goes to the Hayden controller and the unit will not activate.

I'm actually only using the "high" function of the Taurus fan, wiring in the low side was too complicated as you need a lockout to prevent the low and high from coming on at the same time. Also when I had it wired up manually low didn't seem to do much.

So far its been a good mod, only draw back is that it does suck back the power. I worry about draining the battery at idle and I will mostly likely upgrade the alt very soon. Warm up at cold temps ar super fast, 5 min to operating temp at -25C. I still had some overheating issues with it last summer but I think my rad maybe plugged with mud and I usually forgot to engage the fan till it was getting hot(3/4 mark+). However simply stopping and idling for a few minutes brings the temps back down super quick.

A good upgrade though and I like how easy it is to work on the engine. I've had to do an alt and PS pump since it went on and not having the mechanical fan in the way makes it easy to work on.

I've been carrying the mechanical fan for a a few months now as a back up, since the shroud is still there it would be easy to put back on, but its been working pretty good since the Hayden controller went in so I think I can leave it a home now.

I do think I'll need a bigger alt though. I fried my first one not too long after installing it but I didn't have the Hayden controller on yet so I often just turned it on and left it on. My second alt with the controller seems to be doing fine but I haven't had it in really hot temps yet.

[rtingdds]

I got a question about my Taurus fan. It's making noise, can I spray lubricant directly into the motor or not?

[ZJ TINS]

Big assed relays cheap

[rtingdds]

For people who have Taurus fan, what alternator you use? or you still use the same factory alternator without problem.
