Random Tech Questions

Flex fans need rpm to move a good amount of air. How old is your fan clutch? From what I've read a stock fan with a good clutch should pull a lot more air, especially at idle, than a flex fan. You can also look into stock fans from other vehicles. I'm pretty sure I've read about a fan swap before where someone found a fan with more blades from a cadillac or something and swapped it in.

I would go ahead and go with an electric. Seems the jeepers are always ruining a good radiator when the fan gets into it. Just not much room under the hood.

taurus or mark vii

if you get taurus make sure you get the 2 speed as the motor is smaller and go ahead and grap a fan controller out of a volvo while you are at it

I am hoping to try and gain some space between my fan (clutch) and the radiator while possibly helping the engine stay a little cooler. I know 215 isnt causing any immediate damage but when im turning higher rpms the engine stays around 190 so I figured a flex fan might help both issues....

The mark vii fan has weird mounting brackets and will require you to get a bigger alternator. At least I had to on big nasty. Though it was by far the most awesome e-fan I have ever had.

The fan clutch has been on the jeep since i have had it (8 years) for all i know its original.
I thought the idea of a flex fan is that it moves more air at lower rpms and less air as rpms increase and the blades flatten out?

I would really prefer to ditch the clutch. I was hoping a flex fan would be a good option but if it wont be able to do as good as the stock set up than electric would be my next choice. thanks for the advise

ford contour fans are the way to go, they kick taurus fans a$$. look in my build thread

I don't know but it is one unit that has two relays to control a two speed fan built in.

I just saw it an yanked it

I had a flex fan on my jeep. Not sure if it was original. After eating the radiator too many times due to too close clearance, stock skid plate, and stock motor mounts, I swapped to the electric fans from 03 chevy malibu. I will eventually switch back to a mechanical fan.
