Product Details

The Dayco 89166 Accessory Belt Idler Pulley is a precision-engineered OE replacement component designed to maintain optimal serpentine belt performance in your vehicle's accessory drive system. This flat steel pulley with flange features an 80mm diameter, 22.7mm width, and 17mm bearing ID, accommodating belts up to 4 ribs wide.

Key Features:

  • Constructed from specially formulated glass-filled polymers for high-strength performance and maximum wear resistance
  • Advanced 3-D computer-aided design and finite element analysis ensures optimal structural integrity
  • Engineered with smoother surfaces and tighter dimensional tolerances to reduce vibration and extend belt life
  • Lifetime lubricated ball bearings with double high-temperature seals for peak performance
  • Single-bearing design with flat steel construction and integrated flange
  • Cooler running operation reduces heat buildup in the drive system

This idler pulley is designed as a direct OE replacement for power steering and accessory drive applications. Backed by Dayco's limited warranty, it provides reliable performance and durability. Sold individually.

Easy order so far

Best price I found on this product by quite a bit. The order process was simple.

Great online shopping experience. Smooth and easy transaction and shipping was fast. I look forward to doing more business with you guys in the future. Thank you!

Excellent product and price.

Fast! Easy to checkout with Amazon.

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.

So far everything seems good.

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.
