Awful noise on cold start... 6.7 cummins

[Kaukerjoe]

So this has happened twice now upon cold start, in massachusetts temp about 40 but sat all day yesterday and now started this morning to an awful squeal/rattle. (Video Attached) Last time it did this was about a month ago same situation very cold. Noise went away today after about 30 seconds and was even shorter duration the first time it happened. Wondering if anyone else has heard or seen anything if the sorts, either way take a listen it sounds like HELL! First thought was that it was from air dam shutters opening/closing but i kind of doubt it based on the noise.
Thanks
Joe
