Help Needed Please 2017 Rogue engine noise with video.

Longtime lurker, first time poster!
Any want to take a stab at helping me diagnose this noise coming for serpentine belt area.
This had some water damage if that helps.

Thanks if anyone can help. Got lots of time on my hands now

Sounds like pulley bearing noise to me. You can have a mechanic use his stethoscope to determine which one is going bad.

Perhaps the belt tensioner. Check on it.

If not idler pulley.

Or ball bearings.

Casperfun,
Thanks Pal!
I will check them out over the weekend!!!
Thanks again for your time.
Much appreciated!

Take the SERP belt off and spin the pulleys by hand. Another method it to give each pulley a small shot of wd40 one at a time directly on the central bearing when the sound changes or goes away you’ve found the culprit.

How did it encounter water damage? Maybe you can still have it checked by the dealership if it's covered under warranty.

WD 40 can help you identify the bad bearing. Make sure you don't spray it on the belt. It can dry it out and make it wear out prematurely. Also, if you use WD 40 on a bearing, it could thin out what grease that is remaining and make it wear out faster. Anyway, replace it as soon as you can. If the bearing locks up, It will cost you a lot more money and probably leave you stranded.
