    what a peice of junk. the pully squeals intil thet bearing heats up. it also jumps. i've returned it 3 times and it keeps doing the same thing. save yourself some trouble and go to napa and get the oem replacement for the same money. the pully is plastic on this one.

      does this have a range indicator with it, or is it built in to keep the proper tension at it high and low ranges?

        This Dayco No Slack Automatic Belt Tensioner, Light Duty - part# 89223 is designed to maintain constant tension on serpentine belt drives. Serpentine belt drives consist of a single belt that powers most, if not all, of the engine’s accessories.To maintain the proper tension throughout the drive, an automatic, spring-loaded tensioner is incorporated into the drive system geometry. Dayco’s Automatic Belt Tensioner features a patented “flat spring” design that’s engineered to provide less operating range variations in tension. This reduces the risk of premature accessory bearing failure due to high tension when a new belt is installed. It also lessens the risk of belt squeal and slippage, or poor accessory performance caused by low tension after the belt begins to stretch and wear. A Teflon strip wound within the spring resists abrasion. The flat spring itself is coated to resist rust. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.
