Flex-a-lite 274 electric fans verses stock..

Has anyone replaced their stock fan setup with one of these..or similar.
http://www.flex-a-lite.com/electric-...uper-duty.html

I thought I read some issues with aftermarket electric fans not pulling enough air due to the removal of the shroud...but this fits right up against the radiator and since it is somewhat sealed around the fans it should not matter about the shroud....I wouldn't think

I ask as for one I tow a 5th wheel and anything that helps with mileage like removing the stock heavy fan..well helps. But not if it sacrifices cooling obviously.

I would not consider this at this time accept I keep getting fan clutch codes and from what I can tell it is not chafing wires. It appears to be the clutch but due to the fact that it is mid winter in Maine and I dont have a heated garage...I am limited to how much troubleshooting i want to do in this cold. So on it's own I probably would not just swap to an electric just for some small mileage gains etc but...if I have to replace the clutch well...cost between the clutch and the electric fans is close enough "we calls it even".

But if I have to replace the fan clutch in the end I would consider an electric setup like this...if it works well. I like the controller option and the fact it also mimics the clutch signal to eliminate the error code?

Anyone have any feedback.

Actually as I look at the website I see that it is new for 2014 ( this version at least)...so no one would have tried one. But maybe other styles have been tried. ( Edited)

I've always heard that if you tow, just keep the stock fans. The flex-a-lites don't move as much as air as the stock unit does. But that's hearsay. Maybe someone who's had both can give you real world numbers and facts.

I guess one would have to know what the CFM of the stock fan is at max RPM. Maybe I can find that out.

Of course..as you said better if someone who has used one could say for sure.

From doing a quick search, no telling how accurate this is, the stock fans move 10k CFM.

Check this thread out... here

Yah I just read that too.

Also read that Flex a lite does not recommend using their fans if you tow over 10K. So ends that idea.

Not a big deal...if it turns out to be a fan clutch that is gone I have plenty of time to fix it when I do the oil cooler etc. Just a thought while I had it all apart and if the flex a lites worked it would open up some room under there.

Oh well......but then again read several threads where guys were towing heavy( supposedly) and did fine.

Not in the position to be the one guy who did not do fine.

Now the ones I am referring to also are not available yet according to Flex a lite..this was not the older setup....does this make a difference...not sure.

I've ran the flex-a-lite fans with zero issues along with many others. I know guys that have towed with a combined weight(including truck) of22k lbs with no problems what so ever. Even in summer time in stop and go traffic...no problems.

I appreciate the response...I think your responses were ones Iw as referring to in previous threads.

I know this design is new as it is not available yet.....although not sure what exactly is different from the older version unless it was that it was not made specifically for the 6.0 at the time?

Again thanks for the response!!

Correct...they just came out with the 6L kit. It is available right now...summit and jegs sells the 6L kit. Most guys including myself ran the flex-a-lite kit for the 7.3 powerstroke.

How loud are these fans. I would imagin at idle or low speeds it would be louder than a stock fan if they run all the time?
