electric fan conversion??

[mattzj98]

i know it's been done, I know people like to use a ford taurus one most for whatever reason.. anyone ever done it? how do you make it work with the thermostat? should I just wire it and put in a seperate switch??

I usually have no issues running the jeep BUT Carnage Canyon was very slow, and I was using a lot of horsepower, spinning wheels and not moving a lot.. it got pretty hot.. really hot if u've seen the video..

any info would be apreciated!

[Robert B]

my dad just added an electric fan in front of the radiator on a switch in the cab he could turn on when needed on his old bronco if i remember correctly :) probly easiest

[mattzj98]

problem is, i have no room in front of the readiator my grile is very close to it..

[Squshiee1]

Can you cut away the inside part of the grille?
I have an electric fan on the passenger side of my radiator, it cools the trans lines, oil lines, power steering lines, and the main radiator tube! The fan is very loud but it works wonders!

[mattzj98]

im gonna have to look at that.. I have a grille pieces still from the last jeep I rolled so i can prolly check it out

[Squshiee1]

mine is hooked up to the thermostat and the trans temp sensor, the fan usually comes on when the trans gets hot, my engine never gets to hot.

[ROKTAXI]

I put one on my '94 XJ. Got all the info from NAXJA.

[mattzj98]

would it be the same for a big dodge truck V8?

[ROKTAXI]

The wiring is the most important part, as the fan has 2 speeds. You have to decide when you want the fan to come on. I put a thermostat on mine (for the low speed) and that is what switches the fan on / off. Then I use a toggle switch for the high speed.

edit: Be sure to use quality relays!!!

[transplant87]

i picked up a high speed fan from auto clone and its pretty thin and works great. i just have mine wired to a switch

[mattzj98]

thanks for the info

[4Runninfun]

The taurus fan is used because it's a very large fan and Taurus's are very common to find in most wrecking yards. Also what marty said you definitely want to use a thermostat, with good quality switches and relays. I would also wire in an interrupt so if you find yourself in deep water you can stop the fan from deflecting and hitting your radiator.

[Fordguy77]

I've got a tarus fan on my 70 just wired into a switch. Tarus fans work pretty damn good. Ever been next to a tarus in traffic? **** the only thing you can hear is its fan.

so i wonder if i can just somehow add that Fan as a secondary and wire to a switch.. but where to put it? how to mount.. so many questions.. seems so simple

[Fordguy77]

You might be able to reverse the polarity in the wiring and make it a sucker and not a blower? So you can run it on the back side of your rad.

You also may just want to leave the existing fan set up and run an after market fan on the front of the radiator controlled by a simple switch. If the rig starts to overheat, simply flip the switch on and pull air through the radiator.

You may also want to add some hood louvers/vents to the heap's hood to dissipate some of the heat.

A lot of people do both...as well as turning the heater on when the engine starts running hot. That last has only been common practice for 60 years or more...

What year Taurus has one big fan? I ask because I just did a waterpump on my 2003 Taurus this weekend and it has two small ones, not one large one.

[Jim]

Taurus fan conversions have been hashed, extensively, on JeepForum.com Here are my URL's that I have specifically saved as I may one day do the mod (I don't like the noise the stock fan has - though it seems the mod fan is loud too).

Reviewing a few - this thread might be decent help (tho it doesn't say years)

I have a junkyard fan from some Yota I got for $17 and set it up to run as a puller on a switch. It has worked just fine for years. I have used the double fans and single fans on a mess of different makes and models and didn't notice any real difference in temps between the single or double. I have also spent big bucks on the Black Magic fans and noticed no difference from a junkyarded fan. All were set up with a simple switch and were wired for either a push or pull.

The addition of some sort of louvers, whether you junkyard some $30 ones or spend $180 on some, are supposed to dump about 30 degrees of heat. I don't know about the claims, but they work well. What you are concerned about is the low speed heating up, too. The highway stuff sorts itself out. Using a different pulley on the water pump, much like on the PS pump, gets more fluid pumping through the system faster at low RPMS.

[mattzj98]

Thanks, what kind of vent is it?

[Fordguy77]

By big it is meant in terms of CFPM, and tarus fans pump some pretty good cfpm. It is however a dual fan set up, but its one unit.

Spend a few bucks and wiring gets a little more simple. With electric motors on DC current, you can change the wiring to make a fan either a pusher or a puller, so you can adapt them to be used on either side of the radiator. The only issue with that is if the design of the fan will a low it to move air like that. With a little time even it can be adjusted and be corrected to work.
Heres a link to a wiring kit:

They can get more or less expensive depending on what you wanna do. Hope that helps Matt.

Nice write up here:

http://www.higherground4x4.com/Tech%20Cooling.htm

And more information here:

http://www.jeepz.com/forum/cj-yj-tj-jk/22011-elec-fan-upgrade-junk-yard-option.html

If you need more information that what I just added to the huge list that Jim Williamson posted to understand how to do this rather simple add on, then you pretty much need to hire someone to do it for you. There is stuff all over the internet, no matter what 'fan/Jeep' combination you google.

[mattzj98]

Wow, somehow completely missed Jim's post.. thanks Pete and Jim..

Chris, ill take a look at some fans and see how it can be wired, thanks

[Brody]

You should be dealing with just a + and - wire unless you are wiring in a thermostat. Not much more to it than wiring in a light or CB. I never bothered to run more than a simple in line fuse, but I suppose you could wire in a relay if the fan is going to be running for long periods of time. I just bump mine on and off, so a fuse has worked fine.

In addition to the vents and additional fan, you can also scavenge a reservoir and pump for a windshield washer (from pretty much anything), and grab the sprayer parts. Rig the power source the same way, again dealing with just a + and -, to a switch(using a momentary on switch that you have to hold in the 'on' position), plumb the sprayer part so that it sprays down or up onto the front of the radiator, fill it with plain water, and when the temps starts to rise, simply hose some water onto the radiator. This also works well. If you can't find a sprayer nozzle that works for you, grab some small brass tubing that fits the rubber hose and dimple the center with a small screwdriver so that it 'sprays'. This was common on a lot of the older van sprayers, BTW.

Hope that this helps.

Still do that every time I come home from Aspen. Every hill I pull. Not really sure if it's necessary, but all the S-10 has is an idiot light and better to be safe than sorry.

[Meatloaf]

FYI I would go without the thermostat. I've got one in mine, and really don't need it. Put a switch in the dash so you can turn it on and off. Having it run 100% of the time will not hurt anything. Will save you some money.

[Hypoid]

Apples and oranges!

A thermal switch can cycle after you shut the engine off and the internal temps spike. With the thermostat open, and the fan running, convection cycles the coolant, stabilizing engine temps.

+1 for relays! I just can't think of any good reason to route that many amps into the passenger compartment, when the device used is not mounted in the passenger compartment. One of my favorite places to find relays is the cooling fan circuit on JY cars. You get a nice high-amp relay for cheap!

[Molley]

i might of missed it but are you running a clutch fan ? if so maybe just switch for solid ..

[Molley]

i might be late to the show ..this is my findings . i have fought hand to hand with cooling . i have run without a hood installed thinking more air to engine ,, no help . i have messed with timing , adding fans , change to hi flow water pump . changed pulley size , made a bigger shoud for fan ,, added stuff to rad fluid ,, raped headers with heat tape , added cooler to engine oil , used rad bag on front of rad ,, run with out therostat ,, all this kinda helped but not with big gains ,, i regeared diff gears and went with under drive transfer case and ...wow cooling fight was over , hope this saves you time money and sleepless night

[mattzj98]

Thanks for input! However, if I regear any lower, I will not be able to drive over 10mph..

[4Runninfun]

I don't know about ZJ's, however I know that the Disco I's have a known issue with their clutch fans. should be a cheap swap, and possible fix.

[mattzj98]

It is a clutch fan

[rudycon]

I ran a lincoln mark VIII (taurus) fan on my 4runner. No mechanical fan at all (The "fake water pump" fan bracket on the 3.0 cost more than going all electric.)

I wound up with a DCControls fan controller after talking to the Mustang guys in Arizona (hot down there!)
http://www.dccontrol.com/constant_temperature_controllers.htm

There are 3 wires on the Ford fan itself. ground, low and high speed. I used the low speed wire. 10 gage wiring was fine.

The auto parts store hayden fan thermostat and relay didn't last more than a year.
I ended up with a dc controls pulse width modified fan controller. These are built in the USA. Thermistor was on the cold side of the radiator. The hotter the coolant got, the faster the fan would run.

The fan would rarely run on the highway. It would run slowly in town traffic and sometimes it would kick up a bit faster on the trail, but never to the full howl you hear on the taurus next to you in traffic on i-25 with the AC on. Sooooo much less noise than the guys with the aftermarket black magic pancake fans on running flat out all the time. Flip on the AC and the DCControls unit will run the fan about 10% faster and never stop running it either.

The DC controls unit never broke. I can't say it is waterproof, but it doesn't seem to mind general 4x4 use. It was easy to hook up and solid state. No relay to hang.

Another great fitting junkyard fan is the volvo electric fan. the shroud is a little bigger for a better fit than the taurus fan on a toyota.
