Serpentine

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.

Dayco is the world's leading manufacturer of high quality OE-spec engine belts and timing component kits. Dayco belts offer quiet operation, efficiency, and maximum service life through its innovative, self-lubricating fabric that provides superior resistance to abrasion. Dayco belts also feature a molded cog design and glass fiber non-stretch cord that are more economical and are designed to run more quietly.
