Product Details

The Dayco 89170 Drive Belt Idler Pulley is an OE replacement component engineered to restore proper serpentine belt operation in vehicles without air conditioning. This precision-manufactured pulley features a 90mm diameter with a 30mm width and accommodates up to 6 ribs with 7 grooves.

Key Features:

  • Constructed from specially formulated glass-filled polymers for high-strength performance and maximum wear resistance
  • Non-flat steel design with flange for secure belt tracking and alignment
  • 12mm bearing inner diameter with lifetime lubricated ball bearings for maintenance-free operation
  • Double high-temperature seals protect bearings from contaminants and ensure peak performance
  • Engineered with tighter dimensional tolerances and smoother surfaces to reduce vibration and extend belt life
  • Designed using advanced 3-D CAD and finite element analysis for optimal structural integrity
  • Single bearing configuration with serpentine pulley type

This idler pulley runs cooler and lasts longer than conventional designs, backed by Dayco's limited warranty. Each pulley is sold individually and designed for truck applications without air conditioning systems.

Very good shopping experience.

Great thanks

Good part, fast delivery

Kind of confusing at first. Home address in Washington, but vacationing in Arizona where the jeep is. Ok now though. Thanks

Ordering was easy ... Now if the 2 day shipping is true it will b awesome

Great service

Very pleased all round.

very easy

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

Very fast shipping, always great prices.

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

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.
