Fan clutch question...

I think the stealership is at it again, but before I go back at them with both barrels, I'm looking for an opinion from you guys.

The fan clutch seems to be sticking at startup for a couple of blocks, when the engine temp is low, like below 100 degrees and I take off down the road. The fan starts roaring like it might do when it extremely hot, which its not.

It didn't do it this winter, but now that is hot outside it does this. But the motor is not hot.

The stealership is telling me the this annoying roaring noise is normal. I say BS.

Do other 6.4's do this?

It is normal for this motor. Because it it electronically controlled it will do some with stuff. Mine does it year round.
You have to remember all the electronics and stuff, fuel cooler too. Turbo electronics.

Mine will usually roar but if I start off the then let up and coast it will disengage right away.
This stragey pays off when towing and it is really hot. This coolant system moves 100 gals a minute.

I towed cross country loaded to 24K combined all last summer in 100 + temps.
