What fan and shroud are you using ?

I have a 1 inch body lift and am using a flex fan and a shroud that I had to modify. But it's kinda open at the top. I gotta use the shroud since I have a.c. . What are y'all using ? Is it safe to go to a little bit smaller fan or would that be pointless and lose some of the cooling of s larger fan just so I can use s shroud ?

Electric.....solves lots of issues....I can turn it off when going through water....I can force it full on when I want.

And it doesn't care where my engine is.

Mine is a Ford Taurus fan with a variable speed controller.

There are a few different links on the fan....this one is pretty inclusive....

Don't be afraid to email them....the guy is very responsive.

Flex-a-lite also makes bolt on kits....but pricey

I'm using a Ford Contour/Mercury Mystique dual fan controlled by a Flex-A-Lite controller.

So.....how do you really feel?

I didn't realize he was like that. And I'm also a member on Pirate...not super active....but I think I've been on there for at least 15 years

My CJ had a flex fan when I purchased it, but after re-gearing it was so loud I removed it and went back to an OEM style clutch type that I retrieved from the boneyard.
It's quiet, it's simple, and it works.



I had an issue because I'd dropped the transfer case an inch, which put the engine at a slight tilt.
All I had to do was drill new mounting holes (shroud to radiator bracket) and put it back on - perfect fit.

Bagusjeep has the original fan and clutch but a plastic shroud taken from some unknown junker. A couple of quick holes and some wires and plastic ties and it sits just where it needs to be.

Puthijeep has all original, the blades did start hitting the shroud when I replaced the motor mounts but it is steel so a little bending and it is fine.

Gladys the J20 has no shroud, just the original fan and clutch. Must find one for her.

All these have the 258ci engine and none have ever overheated sitting in tropical sunshine. The mechanical fan pulls a substantial amount of air, even with an old clutch. Apparently the contour dual fans get close.

BagusJeep lives in Bali.

Do you guys think there would be no effect if I went from 17 to 16 inch fan but a more enclosed shroud.
It's kind of a trade going to a smaller fan so lose some air there but I'm going to a more enclosed shroud so I'll get some more intensity there. You think it will be an overall performance because I had to modify this one to work so its partially open at the top

I have a Flexi Lite in my CJ7 258. Fans are nice but their controller is a little janky. Had control problems wit it. I wired to battery so it would run for a while after shutting down. A little obnoxious, and I could take care of it by wiring to accessory.

All that said, the fans themselves are solid. If you could find a used set, and get a good controller youíd likely be happy. I do also like what others are doing with Taurus fans. Sounds like an inexpensive way to get electric fans.

Cj

OEM fan and shroud.
When I did my 1" body lift. I just re-drilled the radiator mounting holes to put it back so the shrould was centered to the fan.
No big deal....

I was a firm believer in electric fans until the relays started hanging up and burning up the fan motor and as a result killed the alternator. I'd bought a nylon flex fan several years ago that didn't fit and was still sitting on the shelf. I trimmed it to fit being careful to remove the same amount from each blade. Lo and behold it ran smooth with no vibrations.

As my neighbor said the real test will be if it cools on a hot day. Yesterday it was 94* and I took a 50 mile round trip through the country and into town. It held steady at 195-200*. In fact at stop I could see the gauge needle tick slightly as the thermostat opened and closed.

Nice. What I'm really looking for is a way to keep the condenser cool.

I am running a clutch fan but having a hard time finding a shroud to fit. my CJ was frankensteind together and the blade sits lower and off the right of the radiator a bit. Need to find someone that can custom a shroud for me. Think a metal fabricator can get it done?
