the alternator is new i used a 5w30 oil my belts look fine and the power steering looked fine vac lines looked fine i did 2 starts with no belts and only alternator belt on  then i put the power steering/ac belt on then it came back so im thinking it might be the  ac's pulley or bearing or something? but i was wondering if i could get a smaller belt and only have it on the power steering so i can isolate the ac completely and see if the noise goes away but im not sure how id find the size belt to even attempt that  cause i wont be able to tension it id have to get something a tad smaller  so it'll be tight  over the power steering so it doesnt fly off  but idk if im overthinking it or not im a bit lost with the noise its driving me insane
