Automatic Belt Tensioner
Designed to maintain constant tension on serpentine belt drives
To maintain the proper tension throughout the drive, an automatic, spring-loaded tensioner is incorporated into the drive system geometry.
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.
