Engine running loud

Video below. Seems like it could be the belt but I’m far from an expert. It’s a 2014 210. Any ideas??

Sounds like it could be belt related, like bearing going bad on idler pulley or something else. Belt itself could also be worn out, have you replaced it?
You need to be looking back there with light while engine running to see if anything is obvious.You can also remove belt and check each pulley by wiggling to see how much play it has. Something is not right
