dixau11 What about the stock electric fan from a 2.4l?

dixau11 Ok so I'm still confused on exactly what i need for my TJ to do this mod.
Is there a set list to do the ford Taurus fan?
Obviously the fan but what about the wiring, and sensors. What do I need?

sidebar78 I used the Lincoln Mark VIII fan with a relay system from Ray's Auto. he builds them for Ford off road guys and has for years, I cut down the Lincoln's shroud to fit the Jeep.I then used a trunk type weather seal with a sticky strip to seal the fan to the radiator, fabed up a panel and pop riveted it to the fan schroud to mount the Radiator bottle in the stock position. you can reach Ray at 1-770-265-1004.Ray will build a heavy duty enclosed relay system to meet your Jeep's needs. I got an alternator off Ebay for 45 bucks it's a 160 amp Dodge Durango unit that bolts right on and uses Jeep's stock wiring hook ups

Triple88a Yes you're right it took my own time but after all i'm glad i could share this info with all of u, now you guys can use it too mine ended up being under 100 bucks with everything.
01-11-2009 02:40 AM
NalinMFG but you have to figure the value of all the hours of engineering you put into yours... what were you worth, $.35 an hour?
01-11-2009 01:33 AM
Triple88a expensive.. i mean its nice but still for my wallet thats a bit too much.

A little feedback on my fan.. its all doing well, but i still have not hooked up the thermostat to turn it on and off. I might do it over the summer since now i have the option for my vehicle to have tome down time. I currently use a manual switch.

opinions???

Triple88a No problems with the fan in rain. The other day we got like 4" of rain and my fan took it without a single issue.

The one in the link posted by ATL is not the one that goes in the fins it goes in the upper radiator hose and the little black rubber piece in the picture goes over top the smaller cooper line so the hose will seal around it.

I can do all the mounting, switching, wiring without the kit that comes with the Flex-a-Lites. Is the fan shroud worth the extra 150 bucks?

just go to the junk yard and look for the ford taurus with a 3.8 liter motor
thats a 2 speed fan and will cost around $25

heres some pics of it installed
09-04-2008 01:12 PM
coyote99 Here is a link to a full write-uphttp://http://www.parksoffroad.com/j.../flexalite.htm
its for a Flex-a-Lite but the concept is the same and also shows installing the probe sensor.

Flex-a-lite has another temp control switch Part# 31165-VSC Variable Speed Control that is temp adjustable and increases the fan speed as temperature rises so you only use as much amps as necessary to cool the radiator. You can also attach a bypass on/off switch to the unit(for water fording), and an A/C switch that automatically turns on the fan when you turn on the A/C. A little more $$ but I like to set it up once and not just rig something.

I thought this was the sensor, that on Page 1, goes into the top of the radiator and might leak.

I was worried about the same thing at first but After all the problems with were to put the switch and now that I have had to replace one temp switch already I am thinking a little seepage if any at all would be better than dealing with the threaded type temp switch.Truthfully I am thinking about ordering this.
09-04-2008 10:48 AM
slf41002 Sorry Trip I didn't catch that you had reposted to this thread.I missed it but if it isn't too late then the block shouldn't need to be flushed unless you notice the old coolant is real dirty or rusty color.If the coolant is dirty just flush but if it is rusty colored at all it would be time to check other things like the water pump.I have seen that overlooked before.Anyway yes the switch threads right back in.It is just a pain to get the factory plug out!!!! As far as being water proof I have had no problems with water and I have even hosed my radiator out from the outside and inside and then kicked the fan on right afterwords shooting a mist of water across the whole engine and up the windshield.Hey ALT the ebay link you have is the same fan I have and the other is good cause it has its own shroud but I can't see that much more money when the cheaper one works just fine.

Rawkon i just siliconed all the connections in the wiring and thermo switch. I need to get a overide switch put in for mud/water crossings. so far everything has held up but water and electricty together makes bad things happen
09-03-2008 10:42 PM
tn-yj Wow this was awesome. Just spent time i should have devoted to homework to read this whole thread but it was worth it. I learned alot from this about cooling. Thanks guys
HAs anyone foound out how water proof the fans are though? This is an awesome idea with many obvious advantages but I dont want to waste it driving through some water after I get my snorkel and other scuba gear lol

This link was posted on the first page and would have solved most of the problems that were argued over for so many pages. This solves the "which temperature temp sensor should I use" and the even more amusing "where and how the heck do I mount this temp sensor" This link is for a temp sensor that slides into the fins of the radiator (at the bottom) and is adjustable for what temp to come on. I was hoping that someone would bring this back up, but no one did. Flex-a-lite also has relays to kick the fan on when the A/C comes on, and relays that adjust the amps to the fan to control the speed of the fan according to temperature so it doesnt use spike the amps or use more than necessary.

This has been discussed few pages before in detail so if you'd like to, check it out but of the top of my head... having the fan run only when you need it vs having it run full time.. faster warm up time in the mourning since no air is blown across the engine compartment.. increases rev friendliness of the engine (sort of like lightweight flywheel).. frees up a bit of power mainly noticeable in higher rpms.. Air flow no longer depends on engine speed so you can get rated flow even at idle.. at last doing this mod is cheaper than replacing the stock worn out clutch fan with a new one that will wear out agai.. thats all i can think of now.

I know the original fan has a clutch however even with the clutch disengaged the fan still has a bit of drag.

Triple88a Any special procedures on bleeding the block or do i remove the plug and then try to install the thermostat in there as fast as i could while coolant is shooting out like a crazy water fall (but with coolant)? Also the thermostat bolts right in there? I dont need to use another adapter to match the threads or anything?


I'm just trying to figure out what i need before i open up the block and let the neighbors dog lick the coolant off the ground.
08-18-2008 08:33 PM
Triple88a Thank you
08-17-2008 08:46 PM
slf41002 Yeah I found that out real quick.Just a temporary run of the wire to check everything I noticed the fan kicked on around 160 and went back later to work on it some more and to take a few pics and notice as soon as I turned the key on the fan came on so I found the wire the way I had it ran over the engine had got on the exhaust and melted the coating off so that is why the fan was coming on.But anyway I use a 600 degree shielded wire and ran it across the firewall and down the outside of the intake and then down to the switch so not only is it 600 degree wire it doesn't come in contact with the heat of the exhaust manifold.
08-17-2008 04:47 PM
Triple88a Sherman also what kind of wire did you use? I'm pretty sure most wires dont like to be snaked between the headers lol.
08-17-2008 03:15 PM
slf41002 Well I drove my Jeep today and noticed while coasting down a long road going down hill in the shade the fan did kick off for about a minute and then kicked back on so now I am figuring with a 210 fan switch the fan just may cycle like it should even with the switch in the block.I have a 185 switch so that may be the reason my fan runs more than it should.Even though my switch is a 185 it does not kick on until 195 and off below 195 but my Jeep runs around 195-205 so with a 210 switch the fan may cycle like it is supposed to.While coating in the shade the temps did drop around 190.I am looking for a 210 switch now to see if this is the case.I will let yall know cause I know a few of you have the 210 switch and want to get the most efficiency as possible out of there fan.

I would have to say everything would be pretty close to the same for the 4 as the 6 cyl.I have around $100 in my Efan setup and the same setup would work for the 4 cyl also.As far as gains I could feel a better throttle response right off the batt and have since figured up the MPG gain and was shocked that at either how poor my mileage was before or how much of a gain it is now.

Triple88a My jeep also vibrates a tiny bit (mainly my steering wheel) and you can feel it when stopped however i dont find it annoying at all since my fan only runs when in traffic and to be honest, a small vibration in stop and go traffic is the last thing on my mind .
08-15-2008 10:01 AM
slf41002 It did when I first put it in you could feel the vibrations in the whole Jeep a very little but now with the new radiator the whole Jeep doesn't vibrate anymore but if you are up around the core support when it kicks on or is running you can feel the core support vibrate a little.Right Trip keeping it cool is the whole purpose of a fan in the first place so as long as it is doing that and mine runs about 5 degrees cooler than it did with the stock fan and radiator plus like I said the load from the stock fan gone,the loud turbine sound from the stock fan gone,a noticeable amount of trottle responce not to mention a 1.3 mile per gallon gain in gas milage.I have tested it twice from previous results and came up with 1.4 MPG gain the first time and 1.3 MPG gain the second time.
