Wag Electric Fan Conversion

We have done two electric fan conversions, one was on my 88' (mech. fan went through radiator ) and one on my dads choptop.

*Donor Vehicles*
~95-99 Plymouth Voyager (Dodge Caravan, Chrysler Town and Country) year 1995 was a changing year, so some have this fan, some don’t, so take a tape measure.

~80's Chrysler New Yorker

*Background Info*
- The Plymouth fan i run on my 88' gw (daily driver). this fan requires *some* trimming to the shroud. we had to trim the top of the shroud and the corners to fit it on the radiator. this fan is run on a stock alternator, and so far has kept the jeep nice and cool -on and off road.

- The New Yorker fan is an *exact* fit. i think we MAY of taken the dremel tool to a couple edges to push it against the radiator a little better. not sure if this fan will run on stock alternator, as in the choptop we have a hi-output alternator. NOTE: this fan as of now, is UNTESTED. we have wired it up and turned it on and it seems to have sufficient air flow, but as of now, the choptop is sitting in the garage.

*Procedure*
- Remove all hoses from radiator, and unbolt the radiator from the valance w/ the mounts on, set aside.
- Remove mechanical fan and the double sided bolts that attach to the pulley.
- When double sided bolts are out, insert in a bolt with a flat head into the pulley (gets more clearance).
- With the radiator on a table, set the new fan and shroud against the inner side of the radiator.
- You want the fan to fit flush with the "fins" on the radiator, so do the necessary trimming on the shrouds corners, tops, etc. *NOTE* on the Plymouth fan the shroud should need trimming along the top and corners, and on the bottom where one of the hose necks are.
- Once it the fan sits flush, your going to want it attached securely to the radiator. Drill holes through the side radiator mounts (that hold it to the valance) and into the shroud. We used long bolts and nuts to fasten the fan to the mounts.

Reinstall the radiator/fan and wire according to following wiring diagram: (will post in a few along with pics)

If I may,
AC uses a chemical (somewhat akin to your radiator coolant) flowing through a system (somewhat akin to your engine’s cooling system) which must be cooled in a set of fins (somewhat akin to your radiator) in order to work. AC doesn’t bring cold in, it transfers the heat from the interior of your rig to the exterior where the fan is used to blow “cool” outside air over the fins of the AC system so that the heat that your AC system just brought to the exterior doesn’t get brought right back into the interior as it cycles through the system. If the fan weren’t on when the AC was on, your AC would only work when you were hauling booty down the freeway. Clear as mud?

additionally the ac being on causes an increase in load to the engine(which causes the temp to rise). having the fan come on with the ac helps ofset this load (or heat increase)

i've got a fan from a 90's grand am. it is fairly small, and i *think* there is enough room to mount it next to the aux. trans cooler. i'll let you know how it goes.

Has anyone put an electric fan on a I6 258?
I imagine that the double fan dodge minivan or new yorker fits the 360's and not the 258's...

oh yes good point, i do have a 360 engine, which has a bigger radiator then a 258. i guess if you have a 258, just goto the junkyard with a tape measure...you can still use my wiring diagram/directions. i was actually luckey enough to find a GW radiator at the junkyard to compare my fans too

i also need to add the plymouth fan, is a SINGLE large fan, w/shroud covering around it, the new yorker fan is a dual fan setup

I did a dual fan conversion, worked fine, but if I still had a/c, I might consider adding a third pusher fan in front of the a/c condenser. Mercedes does it like that.

If you have a 258, I know for a fact a tuarus electric fan out of a car with a 3.8 engine will work perfect. It is two speed and readily has enough power to use as a primary fan

It is a rather "trendy" swap on Pirate 4x4 right now.

I have not tried it in a fsj, but in a cj, and if I can fit it in my CJ, where I have less than 5 inches between the water pump pulley and the radiator, I know you can fit it in a FSJ.

Why is an electric fan conversion necessary? Is it a much more efficient way to cool? I live and 4 wheel in the desert so any upgrade to my cooling system would be great.

I am considering a body lift so I was thinking that I wouldn't have to relocate the radiater if I did the conversion, right?

HeepofaJeep, I have that same fan (from the tuarus) but I was told that it draws at least 100 amps at startup then runs at 35 amps. Since my stock alt is only about 60-70 amps I need to find another alt.
Anyone want to chime in with what the Grand Wags (with 360) stick alt is rated at?

SJ, i run electric b.c i never wanna go through what i went through the first time again. i broke a motor mount and the mechanical fan went through the radiator, i was 7 hours from home...to be electrical is more covienient too, you can turn it on whenever you want and turn it off too. also when you turn your jeep off you can keep the fan running for extra cooling.

Thanks Youngjeeper. I was thinking of ordering an electric fan from summit, but with your info I may be able to save some cash for otherthings!

The biggest advantage of an electric fan is the ability to turn it off when crossing deep water. The water will do the work of keeping the engine cool, and the fan won't get pulled into the radiator and shred it.
