Keep every belt-driven accessory turning and quiet belt squeal with the Dayco drive belt tensioner (MPN 89618), an automatic accessory drive belt tensioner assembly that applies steady, spring-loaded tension to the serpentine belt. It's a direct-fit replacement for many vehicles, including the 2006-2015 Hyundai Sonata 2.0L / 2.4L and 2006-2015 Kia Optima 2.0L / 2.4L; see the Buyer's Guide tab for the full list.
Over time a tensioner's spring can weaken and its pulley bearing can wear, showing up as belt squeal or chirp, belt slip, or rattle from the tensioner. If a worn tensioner is the cause, this tensioner replaces it and is designed to restore proper belt tension. Diagnose the source of the noise before replacing.
