Product Details

The Dayco 89017 No Slack Idler Pulley is a high-quality OEM replacement component designed to maintain proper serpentine belt tension and routing in your vehicle's accessory drive system. This idler pulley features Dayco's No Slack technology, which helps eliminate belt slippage and ensures consistent performance throughout the pulley's service life.

Key Features:

  • Durable plastic construction for lightweight, corrosion-resistant performance
  • No Slack design maintains optimal belt tension
  • Precision-engineered for smooth, quiet operation
  • Direct OEM replacement for easy installation
  • Helps prevent premature belt wear and accessory failure

Idler pulleys play a critical role in guiding the serpentine belt around various engine accessories including the alternator, power steering pump, air conditioning compressor, and water pump. A worn or failed idler pulley can cause belt squealing, slipping, or complete failure, leading to loss of power steering, charging system problems, or engine overheating. The Dayco 89017 restores proper belt operation and helps extend the life of your serpentine belt system.

everything was perfect from the ordering to the repair

I have attempted to order this item on a few occasions and each time it has been canceled by your business. I hope this time the order can be fulfilled.

Took a little longer to come then expected but the part fit perfectly and is working properly

Fast and easy navigation of the site

Beat all competitions prices and good quality exceeded shiping time was surprised how fast it revived, easy and simple check out thank you

Lightning fast service! Good prices.

Fun enjoyable easy and quick shipping

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

Autoplicity, was very easy to use, very fast, and an enjoyable experience. I would recommend to my closest friends!!
