Keep the accessory drive belt tracking smoothly and every belt-driven accessory spinning with the INA US Accessory Drive Belt Idler Pulley (FP08661). This idler mounts in the UPPER position and installs as a direct-fit replacement across a wide range of Mercedes-Benz cars and SUVs, including the 2008-2012 C300, 2006-2011 C350, 2007-2011 E350, 2007-2012 GL450 and 2005-2011 SLK350 — see the Buyer's Guide tab for the full list of 25 applications.

  • What it does: Rides against the accessory drive belt to guide and route it around the pulley system, keeping the belt aligned as it turns on its bearing.
  • Position: Upper idler pulley location.
  • Direct fit: Designed to replace the original idler pulley on the listed Mercedes-Benz applications.
  • Signs it may need replacing: Bearing noise, squeal, chirp or belt wobble can point to a worn idler pulley; if the pulley is the cause, this part replaces it.

A worn idler bearing can let the belt misalign or run rough. If a failing idler pulley is behind the noise or belt trouble, installing FP08661 helps return the belt to proper routing. Inspect the belt and the related tensioner and pulleys before replacing.
