I am pretty sure most people say that you gain 5hp. I believe 30hp to be a little "high".

i'd recommend it..when i got my jeep it had an electric fan installed already but with wires hanging and not hooked up. I removed the fan clutch, and wired up the fan to a switch...I can definitly feel a difference, i wouldn't say 30hp though..maybe 8-10...but on a 4 cylinder every bit helps if u ask me

I don't know about the 30hp for sure, but it certainly will help take strain of your serpentine belt though for certain, and maybe a little HP gain. But I think it's a good mod.

theres no serpentine

its one beltfor the alternator and one for the power steering

very basic....

good idea to wire it up to a switch...my buddy somehow wired his up to the thermostate sensor or something
he didnt explain much


would i need the fan shroud still? no right?

he used a temp switch which probably cost $30 or more...mine was $5...the only time you need a fan is on a hot day, in traffic, or offroading sometimes...I have a lighted switch mounted right under my temp gauge.

yeah you can ditch the shroud

My set up eneded up costimg me around $45 including the fan, wires, switch, and relay.

You WILL NOT gain 30hp. Maybe 5-8hp, but NOT 30hp.

I noticed a difference in low end power, and being as my engine runs relatively cool anyway, I hardly ever have to use the fan unless I'm idling in traffic. It'll take my temp from 210 to 150 degrees in just 1 minute! Also good for when I go through water, being as my Jeep is stock height, turning off the fan whenever I want is very important.

I say do it, but don't expect there to be any BIG power gains.

Jake

Most people use the fan from a ford Taurus... It's got two speeds and it has a shroud built onto it that fits Jeep radiators perfectly. I have this conversion on my jeep (4.0) and I really didnt notice a HP difference but my engine definatly runs cooler.

A claim of 30 HP is beyond excessive, stock cherokees (for example) get an average of less than fifty HP to the wheel, so 30 HP would be a nearly 50% increase rofl... MAYBE 5 HP... maybe... Those cluch fans really arnt that "hard" to spin and really dont take that much drag off the motor. What is good about electric fans are the fact that they do not slow down when sitting in traffic, your cluch fan speed increases as the engine RPM increases... well, at a light, your RPMs are very low so your fan runs slow. Electric fans continue to pour cool air through the radiator and over the engine even at idle (on the TRAIL )

Anyway, it's a great conversion, frees up tons of space in your engine compartment, looks awsome, cools better, and does offer minimal HP gains. As for "easy" well, it's as easy as wiring offroad lights, you have two wires, a switch, and a battery, and your done. A lot of people (including myself) buy a "thermostat switch" which is a probe that you put between the fins on your radiator and it turns the fan on at a predertimined temperature, this keeps the fan from running while on the highway or before the engine heats up which saves draw on the battery. These switches can be purchased from advance/autozone next to THEIR electric fans, and run around $10.00 to $40.00 depending on if you want to set the temperature yourself or not.

Great mod... go for it! its FUN!

I would definitely recommend a thermostat. It takes the "human" element out of it. You don't have to think about it anymore. There are lots of wiring diagrams out there to do it cheap. You could probably do it for $25 to $30.

Im 90% sure their wouldnt be a HP gain unless you completely remove the fan blade and run only the e-fan
reason: It might be less drag on the serpentine which IS ON yj modles from 92-95 pre 92 had saprate belts for ps pump, alt, ect. I thought about doing this mod for the summer time and just incase an overheating issue. but aafter a long search at local junkyards i cant up empty handed just my $0.02

No you wont gain 30 hp, maybe 5. It's an easy mod, pretty cheap, and can be done in about an hour. I picked up a ford taurus 2 speed fan and an DC Control Fk-35 fan controller. The fan controller helps a lot and gets the job done, but the wiring can be done for cheaper, I believe Mr.B has a good write up, post #9 here in your thread.

Is that not a serpentine belt, when only one belt runs the whole show ?
