I have this constant tapping or rattle coming from somewhere on my aux/drive belt and I've narrow its down to either the alternator, idler pulley or belt tensioner.
I know its not major as its been making the noise for around a year now, but would just like some someone elses opinion on which it most likely is, or what you think it could be.
Again I'm 99% sure its nothing major as the car runs great and never had any power issues so its nothing like cam belt or anything...and even if it could be its getting changed again next week when i change my head
Thank in advance
Joe
