After I started my 07 5.9L I got out and walked around the front & heard a noise best described like when you were a Kid and you used a clothespin to attach a Bicycle playing card to the fender brace or frame and when you rode you had a sound as the card struck the spokes. This is what it sounds like to me.
I looked to see if the fan blade was hitting anything but don’t see any thing. So I shut it down looked every place I could see & I rotated the fan blade several times & no noise of it hitting anything. Before I take it in does or has anyone heard anything like this? I don’t believe this sound is anything I have heard before as standing in front while running it is obvious so it would be hard to miss. I can feel some vibration when I touch various locations like Valve Cover, Alternator etc.
