Product Details

The Dayco 89345 is an automatic belt tensioner designed to maintain proper tension on accessory drive belts in automotive applications. This OE replacement tensioner features advanced engineering to ensure reliable performance and extended component life.

Key Features:

  • Patented flat spring design reduces risk of accessory bearing failure
  • Minimizes belt squeal, slippage, and poor accessory performance caused by low tension
  • Rust-resistant coating on flat spring for enhanced durability
  • Heavy-duty cast aluminum spring case resists cracking under stress
  • Heavy-duty cast aluminum arm provides additional strength with less distortion
  • OE replacement quality for reliable fit and function

This automatic belt tensioner is designed for air conditioning drive applications and is sold as an individual unit. The aluminum construction ensures a balance of strength and light weight, while the advanced spring mechanism maintains consistent belt tension throughout the life of the component.

Easy to navigate, found what I was looking for. Will definitely be back for more.

Purchased my mishimoto heat tape. Cheapest price around and the shipment was delivered in a very reasonable time. Couldnt be happier

Best price on the internet for my parts. Shipped out the next morning.

Very fast shipping, always great prices.

shipped fast, cant wait to put it on the jeep, would buy from here in the future.

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
