someone help, this is my problem... couple of weeks ago my car been in an accident with the front end. total to fix is 8K. besides that point when i got my car back my alternator pully was swap out for another pully that have four groves in it, lucky when i confronted the shop that fix my car i got the pully change for no charge but my problem is this. after they had change it, every time when i start the car there is a weird belt or grinding sound coming from the the alternator side of the car. (when they put the pully on, the shop pull out the AC compressor and the idle screw-not sure what to call it, its that wheel that goes on top of the belt to tighen it- i am not that mechiancally learned)
if anyone have any idea how to fix it, tell me. dont want to pay anymore. thank you in advance
