When accelerating in the lower two gears of my 2001 Mitsubishi Diamante, I hear a loud, rotational squealing noise from the right side under the hood (adjacent to the right-front tire). However, when the transmission up-shifts the 2nd time, the squealing instantly disappears. It has gotten progressively worse over the last couple weeks, and I've also started smelling a slight burnt rubber smell from time to time. It seems very likely to me that a belt needs to be adjusted and/or replaced, but if so, which one?

It has been difficult to catch it making the noise in park, but the one time I have caught it so far, the squealing was loudest right next to the washer fluid reservoir (red circle in picture).

I can't get it to make the noise now, even with the wipers/lights/stereo/AC all blasting. Seems like it'll only do it on a cold start.
