Looked at the truck real quick last night. The K and N filter element had a couple of "folds" on each side of the gaskets where the housing seperates. I had put a little adhesive to hold those in place last summer. ?? Not sure if its enough to make the noise or not??
The fan clutch was able to spin by hand. I rolled it a couple revolutions. There was some pretty heavy drag, but it kept going. I think I was going the right way...from driver's side towards passenger's. I will look at some of the other threads here, someone stated should on be 1/4 turn or so?
Truck was stone cold, hadn't been drove in a couple days AND it was less than 10 degrees.
Still looking...
