Product Details

The Dayco 89204 No Slack Automatic Belt Tensioner is designed to maintain constant tension on serpentine belt drive systems, helping to resolve common issues such as belt squeal, improper tracking, and accessory component failures. This professional-grade tensioner is engineered to outperform and outlast OEM parts.

Key Features:

  • Patented flat spring technology provides consistent tension throughout belt life, compensating for stretch and wear
  • Heavy-duty cast aluminum housing and arm resist cracking and fatigue
  • Steel locator pins and arm plates ensure proper installation and durability
  • Reduced operating range variations minimize risk of premature bearing failure
  • PTFE-coated spring resists abrasion and rust
  • Deflected arm plate dampens movement to prolong tensioner life
  • Thermoplastic rubber spring slot plug helps keep out contaminants
  • Meets or exceeds OE quality standards

The innovative flat spring design allows for increased torque transmission to the belt when needed while maintaining constant tension, reducing the risk of belt noise, slippage, and poor accessory performance. Built to withstand extreme drive demands and harsh operating conditions, this tensioner delivers reliable, long-lasting performance.

Great products and price and car fitment check

found what I was looking for fast .

Very quick and easy.<br>I hope the installation goes the same way.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

I was searching for brake rotors on the Internet for over 3 hours tring to find the best prices-- Autoplicity beat everyone hands down! The best deals out there. Quick response and my order shipped within one business day! Bravo. <br><br>Their website could be improved by auto selecting make/model combinations. I had to double check the part numbers for the pads..they matched the rear pads with the front rotors. I only caught this due to the fact that the pads were extremely cheap..too cheap. The low price was for the rear set as front pads usually at more expensive due to their larger size.

I couldn't find this in stock anywhere! Not only did Autoplicity have it in stock they were about $10 cheaper than any other sites list price. Received the package very fast! Will use Autoplicity for all of my part needs!
