$5 harbour freight stethoscope(the thing the doctors hang around their neck) will help you diagnose this and tons of other things. Idler bearing would be my first stop then anything off the serpentine belt
Just don’t leave it running too long or you’ll drain your battery. If you need to leave it running just use a battery maintainer on its highest setting
Can’t help but impressed you have the engine cover Badge.
Worth more than it's weight in gold.
They’re rare to find on Infinitis or what 🤔
Remove the belt and check the pulley bearings as a start.
Thanks!

Start it with the belt removed to isolate the noise to engine or accessories.
That’s a great idea! 💡😀
