Keep your timing belt quiet and correctly tensioned with the Dayco Engine Timing Belt Tensioner Adjuster 85041, a hydraulic timing belt actuator that installs as a direct-fit replacement across a range of Hyundai and Kia V6 engines. It drops in for the 1999-2001 Hyundai Sonata [V6-2.5L] and 2001 Kia Optima [V6-2.5L], plus the 2002-2005 Hyundai Sonata, 2001-2006 Hyundai Santa Fe, 2003-2008 Hyundai Tiburon, 2005-2009 Hyundai Tucson, 2002-2006 Kia Optima, and 2005-2010 Kia Sportage — all [V6-2.7L]. See the Buyer's Guide tab for the full application list.
The timing belt tensioner keeps the correct amount of tension on the belt so it stays seated on the cam and crank sprockets and drives the valvetrain in time. Over time a hydraulic tensioner can lose its damping or leak down, which may show up as belt rattle or whine, often at start-up. If a worn tensioner is the cause of those symptoms, replacing it with the 85041 restores proper belt tension. Because access requires removing the timing cover, many technicians replace the timing belt and related components at the same time. Manufacturer part number 85041.
