so saterday i plan on replacing my radiator, and ripping out my mechanical fan and replacing it with and electricall on. Im doing this to try and rob more power out of my little four banger. Any tips or words of wisdom from the jeep gods (you guys).
-
make sure the mounts have rubber on them or it will vibrate bad. and if you just put it on a toggle switch, tape a note on the dash board for a while so you don't forget turn it on. other than that go for it any power helps.
-
my motor mounts are maybe 4 months old, they got replaced when i fixed my exhaust manifold, and as for the power to it i ordered a thermostat today, so till it come im gonna run it on a toggle switch, but once its here thermostat will take care of it.

Once you rip out the fan and fan shroud, then you are going to be left with a huge "gap" between the 4 banger and the radiator.
The "gap" in question is termed by the scientific community as the "Time-for-a-V8-Swap" gap. :hump:
-
hmm yea i realized i was thinking more along the lines of a 4.3l vortec, but a v8 could work :D
-
i meant make sure the fan is mounted on rubber or it will vibrate not the motor and a v8 is just giving up too easily

Having done this same modification to my jeep, I would suggest using a relay in your system. You do not want to send 30+ amps through a cheap wal-mart toggle switch if that is the way your are going. I personally have a 2 speed Taurus fan with a toggle stich for which I ran 2 relays. One for high, one for low. I actually never even use high.

Aww ya beat me to it. Definately a relay system. I have had an electric fan on my Jeep for most of a year now and I had a electric fan on my 91 Mustang GT Vert too. I have gone through multiple used electric fans until I got these last ones. I think I went through 5 electric fans on the Mustang until I bought a Volvo V70 Fan and shroud, and it worked AWSOME! It never failed.
The Jeep has been through 3 electric fans, all off of Ebay. They would work for a few months and then give out. I finally bought a BRAND NEW 16" fan from AZ and mounted it. It did fine until I went over a bump in on my property and almost jumped the Jeep and the fan came loose from its mounts and ended up destroying itself. Luckily I had a Brand New 12" that I immediately installed. It has been doing MUCH better. I mounted the 12" much sturdier than the 16". I plan to take the 16" back since I have only had it for 3 weeks and the mounting pieces that came with it were what failed to keep it secure on the radiator.
The main thing is to get a NEW Fan to begin with and Mount it with a good solid mount but with rubber bushings or foam between the fan itself and the mouting brackets. Most of the new ones come with foam to go between the fan and the radiator, USE them if you have them and make sure there is nothing obstructing the fan spinning.
For my Jeep a 12" is plenty because I am running a 165 degree thermostat but I would usually run at least a 14". The 16" blew A LOT of air. You could hear that thing coming it was pushing a ton of air.
I have mine wired through a relay that is connected to the ignition through the fuse box behind the dash to come on when I turn on the key. Works great. My Jeep stays at a constant 165 all day long in traffic.

aw the 4.3 vortec.. we have 2 at our house.. 1 in my s10 still runs good with power(needs a clutch but thats erelivent) and 1 is siting in our garage wating for a home... my dad wants to put it in our extra cj2a butu i kinda want to put it in my jeep.. were will it go only time will tell.
-
yea i kno a bout the relay, also im putting a fuse, comn guys im not a noob, i just disappeared off this site for a while. I ripped the radiator out, and a/c system it was dead anyway, now im gonna go fab up my brakets to hold my fan to my radiator. ill be done morow so ill post some pics up then.

What is that fan from?
-
is that fsan realy big enough to keep the motor cool.. cuz i have to fans about that size in my shed form a ford torus and i thougfht i had the wron ones cuz they were so smal
-
no idea what the fan is from my friend didnt use it when we swaped a 350 into his nova so he gave me it. It keeps the temp around 190, and it has a 190 degree thermostat in it so it seems to be good, if it becomes bad ill let yall know.

Is this Mod any good for the high temps of Las Vegas??? Gowd i would hate to do this and have it over heat over the next summer. nothing worse then 110+ and running low on water....
-
what intake tube do you have on that motor? i have never seen one that sticks out over the front like that.
-
its some ghetto one i got off ebay, the way its designed its soposed to go cross the valve cover, but it does have the height, so i just ziptied it out front, still work the same. I got it off ebay for like 40 bucks a year or so ago. Work fine, and its beat the hell outta spending 200+ on a k&n setup. Didnt come with the K&n filter tho that i bought last month.

I'd make sure you get one with a large fan. A ford Taurus/3.8L fan is popular. One guy used a Mini's fan. THe main thing is to try to get a fan that covers as much of the radiator as possible and has enough CFM to pull air though.
I've heard of some people going to electrics and haven't overheating problems but those are with off the shelf FLex-a-lite universals. I haven't heard of any complaints from the Ford fan other then the huge starting load.

well i had my first problem today. I was crusing down the road, and went to turn off my fan b/c i was getting on the highway, so i flipped the switch, and my stereo went dead. Turns out my relay was back feeding my acc line which i wired the fan switch into. So i went toradio shack spent a whole 74 cents and bought and wired in a diod. worked like a charm.
