Silence belt squeal and keep every engine accessory turning with the Dayco Accessory Drive Belt Tensioner Assembly (P/N 89304), an automatic tensioner that applies steady, self-adjusting load to the serpentine belt so it stays properly tensioned across the drive. It installs as a direct-fit replacement for the 2001-2006 Hyundai Santa Fe [V6-2.7L], 1999-2001 Hyundai Sonata [V6-2.5L], 2002-2005 Hyundai Sonata [V6-2.7L], 2003-2008 Hyundai Tiburon [V6-2.7L], 2005-2009 Hyundai Tucson [V6-2.7L], 2001 Kia Magentis [V6-2.5L], 2002-2006 Kia Magentis [V6-2.7L], 2001 Kia Optima [V6-2.5L], 2002-2006 Kia Optima [V6-2.7L], and 2005-2010 Kia Sportage [V6-2.7L].

  • Automatic operation: self-adjusting design maintains consistent tension on the serpentine belt.
  • Serpentine belt type: built for serpentine accessory drive systems.
  • Single flat pulley: one pulley, 82 mm diameter and 26 mm wide.
  • Rotation direction: counter-clockwise.

A worn tensioner can show up as belt squeal or chirp, belt slippage, or a visibly loose belt. If a failing tensioner is the cause of those signs, this assembly replaces it. Diagnose the source before replacing, and inspect the belt and pulleys at the same time. Country of origin: United States.
