🔌 Function

Maintains the required belt load and damps belt oscillation as speed, temperature and belt length change.

⚠️ Common Signs of Failure

  • Belt squeal or flutter
  • Weak spring force
  • Tensioner-arm oscillation
  • Pulley bearing noise
  • Repeated belt wear or loss

🛠️ Service Notes

  • Renew the belt whenever the tensioner is changed, and check every pulley in the drive for roughness, wobble or a seized bearing at the same time
  • Wind the tensioner back with the correct tool on the drive provided for it; do not lever on the arm or on the pulley, and release it onto the belt under control
  • Check that the arm swings freely over its whole travel and returns smoothly, and that the mounting face and any dowel or locating pin are clean so the pulley sits square
  • Tighten the mounting bolt to the figure in the workshop manual for your engine — an incorrectly tightened tensioner bolt is a common cause of repeat belt failures
  • Run the engine and confirm the belt tracks central on every pulley with no flutter of the tensioner arm
