Detailed Description

Dayco 89611 is an accessory drive belt tensioner assembly engineered for the serpentine belt system used on 2002-2008 Mini Cooper vehicles.

What It Helps Address

  • Belt squeal caused by weak or inconsistent tension
  • Serpentine belt flutter or misalignment
  • Accessory drive noise from a worn tensioner pulley
  • Reduced belt control in the engine accessory drive system
  • Premature belt wear from improper tension management

Installation Notes and Tips

Verify the vehicle application before installation and compare the existing tensioner to the listed pulley diameter, width, and linear automatic design. Inspect the serpentine belt, idler components, and pulley surfaces for wear before completing the repair. For best results, replace the tensioner when belt wear or pulley noise is present on the Mini Cooper accessory drive system.
