Engine Fan Cycling Issue?

Lately my truck has been cycling the engine fan CONSTANTLY... its been 20 degrees here for a month now and the truck is not getting hot and barely up to temp and it cycles constantly no matter what. If im cruising at 40mph the fan will come on and off every 5-10 seconds and run for about 5-10 seconds and then shut off and do the same thing. It does it at an idle or driving through parking lots as well. Brought it to the ford dealer... replaced the fan, pcm, and fan clutch and still can't get it to stop. Now they are trying to tell me its normal? Just want to see if im crazy and if this is normal although my truck definitely has never done this before this past month or so. If its not normal if anybody knows what the issue could be I would be glad to steer the dealer in the right direction on this one... Thanks in advance!!!

They claim a ford engineer came out and said it was "normal when compared to a like unit". I didn't think it was normal either I will go back Monday and complain some more. Over the past 3 weeks its been there for about 12 days total... I will suggest the sensor also. Thanks!

Mine does the same thing. Almost pointless to leave it idle to warm up.

My truck used to do this all the time, (Being that I live in South Texas and the heat is pretty up there at times) I would think that it was a "normal" thing but at times it would be constantly on. For example driving on the highway it would come on at times and at every other stop lights. It just wouldn't stop. Until one day on the road it began to overheat (was getting on it pretty hard). Took it to the dealer and they performed a coolant system pressure test and found leak coming from the EGR cooler. They found a faulty hose clamp. Im assuming this leak would cause the engine to run a bit hotter at times (not major overheating issues) hence making the fan come on. Truck has been running fine since then and hardly ever hear the fan come on. But since your in much colder temps I would assume it has nothing to do with heating issues.
