Keep the accessory drive belt properly tensioned with the Dayco Accessory Drive Belt Tensioner Assembly 89284. This spring-loaded tensioner assembly maintains steady tension on the engine-belt-driven accessory system, helping the belt stay seated and turning the accessories it drives. It installs as a direct-fit replacement across the listed applications, including the 2000-2006 Audi TT and TT Quattro, the 1998-2006 Volkswagen Beetle, the 1999-2006 Volkswagen Golf, the 2007-2010 Volkswagen Golf City, the 1999-2005 Volkswagen Jetta, and the 2007-2009 Volkswagen Jetta City — see the Buyer's Guide tab for the full list.
Worn tensioners can show up as belt squeal or chirp, belt slippage, or noise from the pulley. If a failed tensioner is the cause of those symptoms, this unit replaces it; diagnose the source first, since a worn belt or another component can produce the same signs.
