Product Details

The Dayco 89652 No Slack Automatic Belt Tensioner Assembly is designed to maintain constant tension on serpentine belt drives, ensuring optimal performance of engine accessories including alternators, power steering pumps, water pumps, and air conditioning compressors. This tensioner assembly features Dayco's patented flat spring design that provides consistent tension throughout the belt's service life.

Key Features:

  • Patented flat spring design reduces operating range variations in tension
  • Heavy-duty cast aluminum spring case and arm resist cracking and fatigue
  • PTFE strip wound within the spring resists abrasion and dampens noise
  • Rust-resistant coating on flat spring for extended durability
  • Lifetime-lubricated bearings with high-temperature seals
  • Smoother surfaces and tighter dimensional tolerances reduce vibration
  • Direct OE replacement design for easy installation

This tensioner assembly helps prevent premature accessory bearing failure caused by excessive tension when new belts are installed, while also reducing the risk of belt noise, slippage, and poor accessory performance that occurs when belts stretch and wear over time. The robust construction and precision engineering make this an ideal replacement component for restoring proper serpentine belt system operation.

Fast Shipping. Good packaging. Very good pricing. Will shop from again.

Best price I could find.

Very fast shipping, item as described. Will recommend.

Easy to work with and shipped in three days for my order no. 5770

Great prices hence why after a search on my desired part why I showed up at their store. Had great communication with their staff throughout the entire process.

Excellent seller, super fast shipping and best pricing on the internet. Thank You!!!!!!

Very competitive pricing (within best 2-3 prices I could find anywhere online) on a foam kayak carrier kit. Shipping was a little high relative to competition, but base price was good enough that with this stellar reputation on RR, ordering from them seemed the right way to go. Ordered 2/17, received it on 2/20 - so *excellent* performance on the delivery side. Satisfied with my decision to shop here. Will eagerly consider them again in the future.

Good enough

Nice to be able to pay with Amazon for an easier purchase

Best prices I can find!

I searched for a quality automobile battery charger and found the best priced and longest warranty "smart" charger at Autoplicity and one other seller. Autoplicity carried a wider selection of the models offered by the manufacturer.<br> Looking over the website I entered my vehicles into the fields and found quality offerings. It is worth looking at.<br> Ordering was straight forward, shipping began the next day with a tracking number, and the order arrived on time. I bookmarked the website.

Quick and painless

Fast shipping! would buy from again for sure! Great product at the best price that I could find!

I placed an order and 2 days later it was at my door!!! Very fast shipping and easy to navigate website! I would definitely recommend this site to all my friends. Keep up the great job!
