  • Includes bearing
  • Direct replacement
  • Built to strict quality control standards
Note for Sprinter Vans: This listing is for one (1) pulley. Sprinter vans have two (2) pulleys mounted directly to the timing cover (upper center and right center). This part would replace either one of those pulleys.

If you are hearing a whirring noise from the front of your engine or if your belt often screeches you may be in need of a new belt tensioner or idler pulley. The idler pulley is typically used to redirect the serpentine belt, or help to apply tension against the belt tensioner.

If you are replacing your serpentine belt tensioner, it is usually a good time to replace the idler pulley as well.
