Product Details

No Slack™ Heavy Duty Automatic Belt Tensioner Assembly (89419) by Dayco®. Serpentine belt drives consist of a single belt that powers most, if not all, of the engine’s accessories. Designed to maintain constant tension on serpentine belt drives, the Dayco Automatic Belt Tensioner features the original flat spring design engineered to provide less operating range variations in tension. This innovative design reduces the risk of premature accessory bearing failure due to high tension when a new belt is installed and lessens the risk of belt noise and slippage, or poor accessory performance caused by low tension after the belt begins to stretch and wear. A PTFE strip wound within the spring resists abrasion and the flat spring is coated to resist rust.

When you need to repair your accessory drive belt system you can battle the traffic and stand in line at the auto parts chain store, only to be told that what you need is out of stock and has to be ordered.

You won’t have those concerns with our replacement drive belt parts. We carry only top name products from well-known OE and aftermarket suppliers. In fact, many of our manufacturers are suppliers to the vehicle manufacturers, so the parts you get from us may be the same as the ones that came on your car or truck. We carry everything from replacement belts to pulleys and tensioners, which will restore optimal rotation speed and quiet to all your underhood accessories. And unlike many other on-line vendors, we don’t just have the big items and let you scramble for the details. We carry everything needed to complete the job.

And the best part is you can have these top quality parts, at the best prices, with just a few clicks of the mouse or a call to one of our knowledgeable sales associates. No traffic, no standing in line, order from the comfort of your home or office. With our drive belt parts you can schedule the repair when it’s convenient for you.
