Fan Clutch

[premirr]

Just wondering if this is normal or not. My fan never stops running. Just to add, it is between 15-25F here in Michigan so its not hot and this is after the engine gets to ambient temperature. It stays at a constant speed and then turns faster, slows back down and then up again. Cycles like this every 6-8 seconds, constantly. I've heard that this may be the "unique fan clutch" that is part of the snow plow prep package. Just wondering if others run like this. Thanks for any help.

Snow plow package? Is that what it says on the window sticker? That maybe the case, but I would think the fan would only kick up like that if the truck was under a heavy load, like pulling or plowing ......also remember it is super tight in there and just because its cold outside don't mean its cold inside that engine bay. To be safe I'd take it in and see what the dealer says

I am having the same problem. Just posted the same thing you are seeing. Truck as been in shop for over 2 weeks. And they still have no idea why the fan is doing that. The computer is telling it NO FAN. But yet its still running a full speed. The Ford Engineer has been out twice in the last week running test. They said its really showing some wacky stuff when Driving down the road with the computer connected to it. There are going to be running more test on the truck tomorrow.

Got General Manager envolved today.

I had the same problem and they just changed the clutch to an updated style and the problem was fixed.
