So my alternator died on monday.

I ordered one from kragen yesterday, and it came today. (No one stocks it)

I open the box- Its the wrong one! The box says 13906 (correct) but the alt has a sticker that plainly says 15906.

SOO pissed. They re-ordered it, but I wont have it till tuesday. Very lame.

I decided to make a dual e fan set up, for more efficiency.

I used some 5/16-24 bolts for the fan pulley. It clears with about 1/4- 3/8ths of an inch.

I then used a piece of angle aluminum, slotted for the fan tabs, and screwed into the old radiator mount.


It uses the right most (passenger) side fan tab, and then the other side for structure.


I then used a piece of steel, normally used to tie wood pieces together, to hold the top on.


I had to remove the top radiator support (PITA without removing the front clip), in order to drill the bracket.

To finish-

I went to Oreilly's and stumbled upon a Hayden fan controller, part #3657.
It uses a probe that is stuck into the fins on the radiator. I like this, because I didn't have to do any plumbing, so it's more reliable. I really didn't expect it to be in stock, but there it was.

It is also adjustable, from 90-210 degrees. It has a little dial that can be turned.
All for $35 out the door. Not bad.

Right now, the fan kicks on below 210, runs for about 20 seconds, and turns off. It doesn't run hardly at all when there is decent airflow in the radiator.

I also wired it to a switch, so now I have 2 separate fan switches, as a fail safe.



The controller.


My favorite part- I used the factory pigtail from the junkyard jeep, and wired it to the controller. I also drilled the shroud so I could use the factory harness clip.


And my 2 switches.


It works well, but the controller is wired to the battery. This mean that the fan can kick on even when the key isn't in. I will fix this soon, by wiring to an ignition (on) source.

I also don't know how long my fan will last. It's old!

I definitely feel like the motor spools faster.

I would leave it so that it could kick on without the key, as long as it doesnt have anyother lights or dodads that would just be a pointless paracitic drain. Because at least with mine, the heat soak used to be terrible! And i wonder how it will be with it as just e-fans. Just a thought.

Nice job all around though! I love that you used the factory pigtail! That is how i LOVE to see stuff done! And super clean engin bay, how do you keep it so nice? haha

Haha thanks man. I was moving some stuff today, I parked the jeep in our driveway. The fan kicked on about 2 times for 15 seconds each, within a 2 minute period, then I think it was done.

I'm obsessed with clean work man. Some of the wiring isn't perfect, but I can fix it later. I'm picky about using conduit! Exposed wires are at risk of abrasion, and it just looks hack.

I clean the engine bay after every wheeling trip, and I rinse it often.

Looks awesome so far man. Remember how I told you your XJ was an inspiration for mine? Well I finally got some Moabs. I hope you don't mind if I post a picture of what seeing your build has led me to appearance wise. I still need to to the fender mod you did because I have 4" of lift with 285/75/16:

The duplicolor works great.

Thanks guys. It is my stock 2001 e fan, and a matching one from a 98 xj.

I took it on a 100 mile trip yesterday (55 miles of uphill dirt trail too) and it got a little warmer than usual, but on steep climbs I turned one of the fans on, and the thermostatic fan rarely turned on. I only creeped past 210 on the most gnarly hills.

My rig weighs about 4100lbs, and we had 5 people inside. We were probably pushing 4900 lbs with tools and gas, so I'd say the fans work. and with 4.56 gears I NEVER have to floor it or anything.

Awesome scenery too.




A little dirty.


And if you'd like to google where we went, the trip was from Arcata CA, to Bridgeville Ca.
All lumber/backroads.
Final stop.

Thanks man! 4.56s eventually since Miami has no hills to worry about.

As always, nice work. Interested to see how the fans work in the heat with the ac on. Might be able to ditch my Taurus fan for a stock XJ one!

Thanks.

I probably wouldn't want to sit in traffic in 80 degree heat with the a/c on, but considering that I was cruising up some big hills, very slow, pushing almost 5000 lbs, and the defroster on, it'd probably be ok.

It's amazing though, around town and on the freeway, the ram air effect is enough to cool the radiator without any fans. My area is freaking cold all the time though.

If I run the switches and turn both fans on, the temp drops WAY below 210.
