Product Details

The Dayco 89493 is a heavy-duty automatic belt tensioner assembly engineered specifically for International Navistar diesel engines. This precision-engineered tensioner maintains consistent serpentine belt tension to ensure optimal performance and longevity of your engine's accessory drive system.

Key Features:

  • Flat wire spring design delivers concentric internal tension for constant, reliable belt tension
  • Heavy-duty cast aluminum construction resists cracking and corrosion
  • Smooth pulley design with 74mm diameter and 39.25mm width
  • Clockwise rotation direction for proper belt tracking
  • Lubricated bearings for quiet operation and extended service life
  • Engineered to protect other drive system components and prevent premature belt failure

Dayco tensioners feature patented flat spring technology preferred by OEMs for superior performance in demanding diesel engine applications. This tensioner is designed to be replaced during belt service to maintain optimal tension and prevent accessory drive system failure.

great to deal with fast shipping good prices and accurate description

Fast, good price

quick great value

Suggest you add "M.I." box to either or both shipping and billing address boxes.

Although you don't offer free shipping to Alaska at least you will ship and not charge extortionate rates. I was astonished how quickly it arrived.

Wow what a deal on mu Subaru husky liner floor mats and low shipping thanks Autoplicity

Great experience

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Autoplicity has a great selection of parts, great companies and great prices. Shipping was very fast and payment very easy. Will be shopping here in the future.

Greta n fast...
