Hello. Today just before replacing the spark plugs I noticed a strange ticking noise coming from under the hood, and specifically from the belt. What do you guys think?

I would get a stethoscope at the local Autozone and put in on the idler wheel to listen to the noise. You probably have a noisy bearing internal to the idler.
Unless your belt has a cut
