Product Details

The Dayco 89485 is a heavy-duty automatic belt tensioner assembly designed to maintain constant tension on serpentine belt drive systems. This tensioner helps eliminate common belt problems including belt squeal, improper tracking, and accessory failure.

Key Features:

  • Patented flat spring technology provides consistent belt tension throughout belt life
  • Heavy-duty cast aluminum housing and arm for superior strength and durability
  • Smooth pulley design with lifetime lubricated bearings for long-lasting service
  • Automatic operation compensates for belt stretch and wear over time
  • Counter-clockwise rotation with 74mm pulley diameter
  • Serpentine belt type with single flat pulley configuration

This tensioner features Dayco's innovative flat spring design that reduces tension fluctuations and helps prevent premature accessory bearing failure. The rugged construction includes steel locator pins and arm plates built to outperform and outlast OEM components. Engineered for heavy-duty applications requiring reliable automatic belt tension management.

Good so far

I had never heard of Autoplicity before placing this order. I found Autoplicity via Google and decided I'd give them a try as they were the cheapest option. <br>Autoplicity did have the lowest price. The order was shipped promptly and got to me 2 days after ordering and the next day after it was shipped. I am very happy with this purchasing experience and would purchase from Autoplicity again without any hesistation.<br>

good

Thanks my complete order is for a 2000 ford ranger 2.5 thanks
