I didn't check the video, but for a 2002 vehicle, I would suspect all the pulleys would need replacing if you haven't replaced them before. The bearings wear out over time. They usually need replacing around 80K miles. Remove the serpentine belt and spin each one by hand to see which one is squeaking. They shouldn't free spin nor be too tight either.
