Moved Alt to A/C mount & Elec. Fan Setup

First,many thanks to rubix-xj & outlander for getting this mod started !!!!!!!

I have been wanting to pull all the A/C related stuff out for some time now,then I read the thread rubix-xj had about putting Alt up top and that was enuff to get started.

Once I got all the A/C stuff yanked I started mounting the Alt in place of A/C compresser.Since I was moving it to a higher place I decided to use my
180A High Output with adjustable voltage regulator Alt. that I used when I competed in USAC Outlaw SPL.

I used the same method rubix-xj used by using the Alt. mount from below,
then where outlander made a bracket for the right ear, I used a bar pin
from a shock,grinded it a little and works fine.

I then decided to go from closed to open system and get rid of my mech. fan & go with a triple 10" setup.I also got rid of the heater valve as well.

I ended up buying a CSF 2-row from Radiator barn,195 deg Robert Shaw premium thermostat,Stant safety rad cap,new style therm. housing,lower hose,77" belt,brass nipples,brass elbow(these are in place of the old SHORT tube coming from pump)and the triple threat elec. fan system from E-Bay.
Here are some pics



Here you can see the bar pin I used.



Here is the old Alt bracket reused up top.


The Fans



Overflow bottle

I modified the Fan control system I received with the fans by adding two more relays and three switches for more flexibility.
Pics of relays. The blue finned part is my adj. voltage reg.


The switches. Top switch is : Off position is Auto Mode / On pos. is just that
ON bypassing Auto mode. Bottom Left switch is the middle fan,bottom right is
the two outside fans. Normal position is On,but I can drop out the mid. fan OR
drop out the outside fans OR drop out ALL three fans.
Then I thought I needed something to let me know my fans were On or Off while driving down the hwy,because I did not think I would be able to hear them.I gutted the clock(broken anyway)put some tint on the display and used the lamp that was already there.
Auto Mode

On Mode

Sorry for the long post!!
I am very pleased with my new setup!!!!!

Nice. Might try the alternator move on my project XJ this summer

awesome! looks great! I just did the same move, but I left everything else the way it was.

What do you do with the A/C lines when you disconnect them??? right now mine are just hanging there...

That is slick looking! I like the clear coolant tubing!

Look at 7th pic towards firewall,just cut then silicone

This is on my 87 XJ. While I was under the hood I also replaced the O-rings
on the filter adapter,new motor mounts from Brown Dog,all new CCV system,
Oil filler cap,temp switch for temp guage,oil switch for oil guage &
valve cover gasket. Took valve cover off to clean and to install CCV.



This is the reason I was originally down.Don't know how I ended up under
the hood?

wow... playin in the rocks were ya?

Yeah,my son & I had her straight up & down in a ravine.Sure was fun!!!!!!

So what did you use for an idler since you eliminated a component didn't the belt become longer? i would like to try this on my project jeep.

The idler pulley is still there and the pulley for the mech fan is still there
as well.Probably could have taken out the fan pulley but I opted not to.
The belt is 77" now.
See pic

wow... how'd I get a 70 3/4in. belt on there???

Good Q,I bought a 76 & had to take it back for a 77"

So in other words i can remove both the compressor and the mechanical fan with no issue. I will just have to put another electric fan in there. Its a beater jeep and i have deamed it the experimental Jeep aswell so maybe i'll give it a try.

Good write up, Im going outside to get everything lined up like that.
Thanks man.

It works

Looks like it's a good idea to leave the fan pully on in this setup, much tighter wrap on the alt pully!

Also I love my brown dog motor mounts, how about you?

I used my origional stock engine brackets (not the Browndog ones) and I found I had to modify the mount bushing to fit. I hat to trim one of the ends of each bushing in order to get it to slide between the motor brackets.

Other than that they are awesome mounts, the Jeep feels much tighter than before.

I was going to say that as well - the extra little bit of wrap you can get from using the MFan pully as an idler should help keep your output up.

I wrestled the drivers side for a while,but it finally went in.
