The belt may eventually start slipping if you overlook the tell-tale
indicators of a worn-out pulley. When the pulley is overly worn, this problem
develops. The engine belt begins to bind and rub against the pulley. Squealing
sounds are produced by this contact, and they only become worse until the
pulley is replaced. In addition, if a slipping belt is not changed right away,
other engine parts may malfunction, necessitating additional expensive repairs.

majority of cars only have one idler pulley, while some, depending on design,
