So, i'm trying to replace my bolt-to-the-crank radiator fan with an electric fan on my '80 CJ-7, 258 I6.

Any suggestions??? Size, Brand, Model #, rules of thumb??

All input will be appreciated.

I know you already know this but

Get the biggest CFM you can get, and get an electronic thermo. so it will come on and off with out worring about a switch..

I know 4wd hardware sells one that will work with the 258/i6

the el cheapo way (my way <IMG SRC="smilies/biggrin.gif" border="0"> ) is to go to a junkyard and get one out of a camaro/firebird (or any V8 late model ride). I don't know how much air they pull but its enough for the V8 and small grill opening that they have so its enough for us. Be sure to use any elec. fan as a puller, not a pusher. Works MUCH better that way.

I went with a Be Cool fan from 4WD Hardware. The part # is 75014 with the #75023 Fan Control Kit. The fan kit turns it on at 195 and off at 180.

It is a 16" fan and does a great job keeping the motor cool. You'll notice a big difference in horsepower with the electric fan. I will only go back to a mechanical fan when I get a V8.

I would find these same parts(or whatever you choose) through Summit. They are way cheaper than 4WD Hardware and they have free shipping w/ no tax.

Puller fans are supposed to be more efficient the pushing fans. Also a shroud is effective for cooling at idle.

You what else would be neat are hood louvers and vents. Every little bit of effort to keep the engine cool will be helpful.

I have a pusher in front with a mech fan in back and in my 51 with a 350 Chev I run at 190* even crawling around in 95* heat.

Flex-a-lite makes a dual fan set-up specific for I-6 jeeps. Part #575 is a direct bolt on with thermostat, super easy to install. It has a built in shroud that fits perfect, Although it is expensive at $350.00. Clifton <IMG SRC="smilies/jeep2.gif" border="0">

The duel fan by flex a crap is just that. I'm running a 16" Spal and it works great. Give Scotts Manufacturing a cal. They carry all the Spal fans and are very knowlegeable.

I run two 12" fans from speedway motors, with an adj. thermostatic switch, they barely fit behind the radiator side by side. The setup works well. I mounted them thru the radiator with the plastic straps it comes with. This I dont like, I am making a shroud to mount them to out of aluminum. This will also increase the cooling action by directing more air thru the radiator. There is not much room between the water pump pulley and the radiator, but these fans are very thin. I think the whole set up cost me around $70 - $80. They may not be the quality of flex a lite fans, but very nice for the money. Speedway is mostly a custom hot rod supply shop, but I have found many things for my jeep there, ie. heim joints, 24" stainless steel brake lines, fans, etc.

Late model Volvo fans kick ass. Some of my go-fast buddy's run them and they say they're the best swap in they've been able to find. I can try and find out exactly which model.

Thanks for ALL your help. I'm going to the wrecker's first, to look for a pontiac/late model v-8 setup. If i can't find anything, i'm go'n with the dual SPAL fans. Their available locally, and easy to do.

Thanks for ALL your help men. <IMG SRC="smilies/biggrin.gif" border="0">
