Car is running fine, but noticed this metallic noise every time I shut the car off... Going in shop next week, but any ideas? Not a pulley or idler.. Noise still emits w/ no belts on shut down....

I'm pretty sure GM declared that noise to be normal. Not shitting you.

No noise.. engine running normal... just sounds like that on video.. concentrate on the split second "grrr" noise at shut down..

Sounds like the belt squealing for a split second.
Never mind, you had the belt off and it still does it

Throttle body sweeping on key-off?

sounds like airflow (compression) to me....

is that a clutched alternator? My 07 gt made a very similar noise it was the clutched alternator pulley

its the idle air motor and tb blades

I have lots of various brands of cars i work on in a collision shop, and they do the same thing. I think its something in the drive by wire throttle body.

Almost sounds liquid? Radiator fluid level?
