Clutch fan and electric fan combo

Has anyone used an electric fan and clutch fan somehow? Just curious if it can be done, and if any cooling benefits can be achieved in doing so....

im sure it could be done. just mount the electric fan in front of the radiator and leave the clutch fan where its at.

actually thought about this today as well haha
Don't the early WJ's have both?
probably not enough room though. It's pretty snug back there with my Taurus fan swap

I think mechanical fan as a puller and an electric fan as a pusher could be done, but the pusher would have to be small and since they aren't as efficient as a puller fan, it's probably not worth it. Is this to keep engine temps in line or to improve ac performance?

I was possibly thinking of moving the shroud, and putting an electric fan in front of the mech fan (if it'll fit), then putting the shroud back into place.
I guess if it'll improve cooling and help the a/c, why not...
I'm mainly curious if anyone has attempted this.

My friends durango has this set up stock, as well as another friend of mine with an xterra. Pretty sure the early WJ's come this way as well, not 100%.

RENIX XJ's had both. The electric was activated by the A/C. But they were side by side.

That's what my 87 XJ had. It was a fifty fifty chance it ever worked, among everything else on that jeep.

Not even for an ultra thin aftermarket fan?

All the OEM setups like that that I've seen were side by side.

I don't see how it would help in any case. A properly sized clutch fan with a good fan clutch should be able to cool just fine. I know a lot of guys have troubles cooling a ZJ with the factory setup but in my opinion adding a pusher to the front probably won't help much. Pushers are very inefficient unless they have very good shrouding. Adding that shrouding would be very difficult in front of a ZJ and with two shrouds you'd probably loose a lot of air flow.

Plus, the electric fan becomes a restriction at roadway speeds. The clutch fan will still be there causing drag on the motor. Sounds to me like you'd get the worst of both fans.

I may be wrong though, only one way to find out.

Another thing I was thinking if it could be accomplished would in fact be restriction like you mentioned.
I probably won't attempt this, it was mainly just a thought, and if anyone has tried this out.
I changed the water pump, 195 thermostat, radiator, hoses, and clutch when I bought the jeep (all appeared to be original) just for safe measure.
All is normal with the cooling, just thought of an updated upgrade like some newer vehicles contain, just to keep the temps a little more stable per say.
