Weird rattling noise coming from engine bay

Rattling noise in engine bay - 2011 Tahoe 180k miles on this engine

Does anyone know what the is rattling might be? It just started on my 2011 Tahoe. It also continues for a couple of seconds when I turn the truck off. Seems to be at least somewhat intermittent because I have turned it on and off a few times and at the moment it’s not making that sound. Sounds concerning. Any help is appreciated!

Thanks for posting the video. The only things that may stay turning after you shut off the engine are the cooling fans. Give them each a twirl (with the key in your hand) and see if either of them are the source of the noise. Ba careful though because the fans can still start with the ignition off and key out.

take the belts off and give everything a good spin by hand, or go grab a stethoscope and listen, shouldn't be hard to find
