Product Details

The Dayco 89245 No Slack Automatic Belt Tensioner Assembly is engineered to maintain consistent tension on serpentine belt drives, resolving common issues like belt squeal, improper tracking, and accessory failure. This premium tensioner features Dayco's patented flat spring technology that compensates for belt stretch and wear while maintaining constant tension throughout the belt's service life.

Key Features:

  • Patented flat spring design provides less operating range variation and reduces premature accessory bearing failure
  • Heavy-duty cast aluminum spring case and arm resists cracking, fatigue, and distortion
  • PTFE string wound within the spring resists abrasion and dampens noise for quieter operation
  • Premium thermoplastic rubber spring slot plugs and O-ring seals keep contaminants out
  • Zinc-coated mounting bolts resist rust and corrosion
  • Steel locator pins and arm plates for enhanced durability
  • Single smooth pulley design with 70mm (2.75 inch) diameter

This automatic tensioner reduces the risk of belt noise, slippage, and poor performance caused by improper tension. Built with tough, long-lasting components, the Dayco 89245 is engineered to outperform and outlast OEM parts while enduring the toughest under-hood conditions.

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim
