So half of the inside (closer to the motor) serpentine belt got ate up when I took it off and inspected pulleys the power steering one was missing half of the backside as well and changed it to a aluminum pulley got a new belt (also installed dp while I waited for parts) first day I put it on the ground it sounds fine for a while and then I started hearing a squeak whenever I accelerated even in neutral I took the belt off cleaned the groves of the pulleys and air pressured all around pulleys got a new tensioner and cleaned alternator (which is where sound is mostly coming from) and still nothing i tried turning the car on without serpentine belt on and it didn't make the noise really could use the help I hate when my car makes noise
Also from the beginning if I sprayed the inside of the tensioner pulley with wd40 the noise would go away

If you spray wd on the tensioner pulley and the noise goes away, doesn't that show where the problem is?

But it's a brand new serpentine belt so I don't think it's that and where I was spraying (the tensioner pulley) is new as well

What brand belt did you use? There’s some manufacturers that are too long and they squeak. Specifically a belt that advanced auto Has.

I changed the belt to a continental and it seemed to go away but rn on my way to work I started hearing it again when pushing on the car more

Belts can be inconsistent in length but 90% of time it's another aspect of the install causing the squeak. I'd double check the tensioner pulley because most likely that's the issue.

The noise went away right as I was down the street from my work place again so if it continues when I leave today I'll take a look at the tensioner pulley maybe I just installed wrong or something

Well it wasnt making the noise after work so after I got home decided it needed a well deserved shower and…. The serpentine belt is now wrapped around my alternator
