Product Details

The Dayco 89629 Automatic Drive Belt Tensioner Assembly is engineered to maintain constant tension on serpentine belt drives, ensuring optimal performance and longevity of your engine's accessory system. This tensioner features Dayco's patented flat spring design that provides less operating range variation, delivering consistent tension throughout the belt's service life.

Key Features:

  • Patented flat spring design minimizes tension fluctuations and operating range variation
  • Heavy-duty cast aluminum spring case and arm resist cracking, fatigue, and distortion
  • PTFE string wound within the spring resists abrasion and dampens noise
  • Rust-resistant coated flat spring for extended durability
  • Thermoplastic rubber spring slot plugs and rubber O-ring seals keep contaminants out
  • Zinc-coated mounting bolts resist corrosion
  • Steel pivot tube design provides increased stability

This tensioner reduces the risk of premature accessory bearing failure caused by excessive tension when installing a new belt, while also preventing belt noise, slippage, and poor performance from insufficient tension. Engineered to exceed OE specifications, the Dayco 89629 delivers reliable operation even in harsh conditions, promoting quieter performance and extended component life.

Great pricing, fast shipping, A+++

Checkout was easy and quick.

Once i installed the BULLY DOG GT TRIPPLE DOG GAS TUNER PROGRAMER on my newerbody style 07 gmc sierra 1500, My mpg average went from 12 to 18. Instant improvement and performance. Not to mention the truck is lifted 7.5 in with 37 in tires. Easy programing settings takes minuets. The power the 5.3 puts out after my Bully Dog gas tuner was installed was fanominal. I will deff get my money back in fuel over about a year. Can't go wrong purchasing. This item. MUST HAVE PRODUCT.
