I started the car up and immediately heard a tinking noise. Lifted up the hood and you can tell just by the npise its coming from belt. I don't know if something broke or if the belt needs to bbe replaced or just greased up. It looks fine n not thin but I'm also not good at cars Lol. If you can help it'd be greatly appreciated. Thank you

Noises from serpentine belts can be caused by them being loose or having insufficient tension from spring-loaded tensioner pulleys, but most commonly it's due to a pulley being turned or tipped, usually from a bad bearing. The noise is caused by the belt sliding across a pulley as it goes around it.

Do not put any kind of belt dressing, or "grease" on a serpentine belt. Dirt will stick to it and cause a lot more noise. The only fix for that is to discard the belt, scrub all of the pulleys with soap and water or an engine degreaser, then install a new belt.
