Probably one of the belts is too loose.

keep in mind that cheap belts stretch.

To figure out if it's a belt making the chirping noise, and not a bearing, drizzle some water from a water battle onto each belt, one at a time. If the noise stops, the check pulley alignments especially the alternator. Washers can be used a shims to correct alignment.

If the chirp remains, then water pump bearing or alternator bearing etc.
