best fan

[DansGreyMj]

i wanted to run another electric fan under the hood and was looking for one that was kinda compact for better fitment, what would be the best car to pull one out of at the 'yard

Are you talking about adding an electric fan to a truck that doesn't have one, or replacing the mechanical with an electric?

[DirtyComanche]

The stocker aux fans work if you want to add a fan.

 

 

To do a conversion you're going to need to run duals just because the rad is such an awkward shape. Well, or one big one that hangs down kinda low.

 

 

 

 

Personally I've got two taurus fans that are supposed to go in once I find time. I'm only doing it so I have the choice of not running them in the winter, and running them while the truck isn't on (short periods). That and I need a little more clearance in that area for something else...

Before I switched to gages in my MJ I got the idiot light to come on a cpouple times last year while out on te trail. I am unsure what the temp was..only that the light came on.

 

I added a factory fan from a AC equipted 4.0 XJ. Now all I have to do is thropw a switch and the temp drops back to about 200 while out on the trail. Works perfectly!! I have the temp sender for the rad in just need to finish rewiring.

 

This is what I would do if I was you,

good luck!!

i meant as in running a second fan, and when u put in regular gauges did they just plug right in or did u need to wire some of them up

I AM also talking about a second fan. The FACTORY added aux fans on XJ/MJ's that left the fact with A/C. If you need an additional fan to those two, you likely have a larger problem than another fan will rectify. I would do a flush and refill and maybe a new radiator. just be sure you get one from a A/C equipted jeep!!!

 

 

For the gauges, just plug in the correct year unit and change out two senders and your done!!!

 

Change out the OIL sender located just below your dist:

 

Then change out the temp sender at the back of the block. be careful there are TWO. the one you want is the harder of the two to change:

 

NOT THIS ONE!!!

 

THIS ONE!!

 

Then its just a bunch of serwes and a bit of cursing and you will have the factory unit out. One tip, the cable is routed thru the dash to a point under the drivers feet. there is a solid mount that attached to the upper control armbolt. Slide this off and you will get about another 6" of usable space to get the speedo cable off!!

 

 

 

All done!!

 

Good luck!!

Before you start your gauge swap, it is important that the donor vehicle (XJ or MJ) is compatible. 91 and 92 MJ's are all electronic (no speedo cable), therefore the donor vehicle should be a 91-96 XJ or 91-92 MJ. If your MJ is a 87-90 the donor vehicle should be 87-90. Am not sure, but i think the 86 MJ has a different speedo cable than the 87-90 models. :idea:

CW nice pics and post. This too should be a sticky, as it is a common swap. For me my idiot lights and no gauges work fine as if I burn Pong up, I have a reason to do a 4.3 swap :nanner:

 

As for running dual electric fans. The horsepower savings in minimum at best and it puts more strain on the notoriously weak stock alt (unless you have the 105 amp one) The only advantage to running 2 fans is if you run in a lot of water or mud, where the mech fan is thorwing mud and water all in your engine bay anyways, but if that was the case you would fry your alt petty darn quick as they don't function well under water :nanner: :smart: Call me carzy, but dual fans jsut don't seem worth it to me :dunno:
