Click Noise Help

[StefanoSPQR]

Can anyone identify this clicking noise in my 2009 Toyota Corolla LE (see link below)? Car only has 78k. Clicking increases on acceleration. Clicking occurs with AC turned off. No dash lights and engine idles smooth. Alternator was replaced around 50k. Water pump replaced around 35k. Noise just started and haven’t driven car since. Occurs when engines is cold or hot.

Thank you,
-Stefano

Take the serpentine belt off and spin each pulley to see if one of them is making the clicking noise. I have a feeling it's the alternator pulley.
