Product Details

The Dayco 89257 No Slack Automatic Belt Tensioner is engineered to maintain constant, reliable tension on serpentine belt drive systems. This tensioner features a deflected arm plate to minimize rotational movement, enhancing stability and extending service life in demanding automotive applications.

Key Features:

  • Heavy-duty cast aluminum spring case resists cracking and rust while delivering quieter performance
  • Specially coated patented flat wire spring allows internal tension to be concentric, providing more even constant tension
  • PTFE string wound within the spring resists abrasion and dampens noise
  • Rust-resistant zinc-coated mounting bolts for long-term durability
  • Built-in locator pin allows for easier installation
  • Lubricated bearings and high temperature seals assure peak performance

This tensioner reduces the risk of premature accessory bearing failure due to high tension and lessens the risk of belt noise and slippage. Designed to meet OE specifications, the Dayco 89257 provides reliable performance across various vehicle applications including cars, trucks, and SUVs.
