Best thing to do is Remove the Belt & Clean all Pulleys & inspect for worn or loose Pulleys, then Replace Belt with new.
Many times road grime, dirt & moisture will get on pulleys & make them squeal, which low RPM's would be worse.
Otherwise I/R allignment may be needed to be sure all Pulleys are aligned
