Product Details

The Dayco 89342 is an automatic accessory belt tensioner designed to maintain proper tension on your vehicle's serpentine belt system. This OE replacement tensioner ensures reliable operation of belt-driven accessories including the alternator, power steering pump, air conditioning compressor, and water pump.

Key Features:

  • Patented flat spring design reduces the risk of accessory bearing failure caused by over-tensioning
  • Maintains consistent belt tension to prevent squeal, slippage, and poor accessory performance
  • Corrosion-resistant coated flat spring for extended service life
  • Heavy-duty cast aluminum spring case engineered to resist cracking under heat and stress
  • Durable cast aluminum arm provides superior strength and minimizes distortion
  • Direct OE replacement for original equipment specifications

This tensioner is sold individually and includes the complete tensioner assembly. Dayco's precision engineering ensures proper fit and function, restoring your belt drive system to optimal performance.

Fast shipping

Overall gods experience

easy

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

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.
