I have a rattling noise coming from the right side if the engine. It does it at idle and when driving. I was told that it could be the pulley for the alternator and was also told it was the AC compressor going out. It's annoying and sometime loud like coins being shaken in a can. What can it be? And what should I ask a mechanic to check?
