Product Details

The Dayco 89393 Automatic Belt Tensioner Assembly is a premium replacement component designed to maintain optimal serpentine belt tension and eliminate common issues like belt squeal, improper tracking, and accessory failure. This 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:

  • Counter-clockwise rotation design with single 90mm diameter pulley
  • Patented flat spring design provides less operating range variation compared to conventional tensioners
  • Heavy-duty cast aluminum spring case and arm resists cracking, fatigue, and distortion
  • PTFE string wound within the spring resists abrasion and dampens noise
  • Steel locator pins and arm plates for enhanced durability
  • Premium thermoplastic rubber spring slot plugs and O-ring seals keep contaminants out
  • Zinc-coated mounting bolts resist rust and corrosion
  • Steel pivot tube on specific designs for enhanced stability
  • Proudly made in the USA

This tensioner assembly reduces the risk of premature accessory bearing failure caused by excessive tension, while also preventing belt noise, slippage, and poor performance associated with insufficient tension. Engineered to outperform and outlast OEM specifications, the Dayco 89393 delivers reliable performance across air conditioning compressors, alternators, power steering pumps, water pumps, and other critical engine accessories.

Ordering was very easy and product was delivered within a week. I ordered a battery and it was received in good condition and works. I would recommend autoplicity to others.

Quick easy site to use

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Shipped very quickly and had the best price I could find!

Great prices on most things. Ordered on a sunday and they processed and shipped the order the next day.

first order fast shipping and great fit

The whole process was some and quick. They also had the lowest prices available. Will be using them more often for sure!!

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.
