Product Details

Built for the accessory drive belt system, this tensioner assembly helps maintain proper serpentine belt tension across the engine-driven accessories. The 76 mm pulley and automatic design support steady belt tracking in applications that require a counter clockwise tensioner layout.

This part cross-references ACDelco 38164 for the same application.

What It Helps Address

  • Belt slack in the serpentine drive system
  • Noise from a worn or unstable belt tensioner
  • Uneven belt tracking on the accessory drive
  • Loss of consistent tension on engine accessories
  • Replacement needs for a worn Chevrolet Cavalier or Pontiac Sunfire tensioner

Installation Notes and Tips

Verify the belt routing, pulley diameter, and counter clockwise direction before installation. Confirm the vehicle application against the existing tensioner layout on your Chevrolet Cavalier or Pontiac Sunfire, and inspect the serpentine belt condition at the same time. Proper alignment in the accessory drive belt system is important for quiet operation and belt life.
