Product Details

The Dayco 89352 No Slack Automatic Belt Tensioner is engineered to maintain constant tension on serpentine belt drive systems, ensuring reliable accessory performance and extended belt life. This precision-manufactured tensioner features Dayco's patented flat spring design that provides consistent tension with minimal operating range variations, reducing the risk of premature accessory bearing failure while preventing belt squeal, slippage, and poor accessory performance.

Key Features:

  • Patented flat spring design with Teflon strip wound within the spring to resist abrasion and wear
  • Heavy-duty cast aluminum arm construction offers superior strength and reduced distortion under load
  • Aluminum retainer ring locks the spring case and arm together while sealing against corrosion
  • Thermoplastic rubber spring slot plug keeps out harmful contaminants and debris
  • Rubber O-ring seals against dust and grime for long-term reliability
  • Lubricated nylon pivot tube bushing and spring bushing promote quieter operation
  • Zinc-coated mounting bolt resists rust and provides concentric mounting for even tension distribution

This OE replacement tensioner is designed for alternator and power steering belt applications. The advanced engineering ensures your serpentine belt system operates at peak efficiency, protecting your vehicle's accessories from premature wear while maintaining optimal belt tension throughout its service life.

Specifications:

  • Material: Cast aluminum construction
  • Tensioner Type: Spring-loaded automatic tensioner
  • Application: Alternator and power steering belt systems
  • Quantity: Sold individually

Best price ever, easy to order

Lowest prices I have found and great customer service!

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.
