Serpentine - Extended Life Accessory Drive

A new automotive accessory drive arrangement known as ‘Serpentine Drive’ has been developed. The said arrangement employs a single, longitudinally ribbed drive belt, “snaking” around all the accessory pulleys to provide the driving force. Belt tension is applied and maintained by an automatic tensioning device, thus, belt slippage, which contributes to belt degeneration through the wear and heat generated in the process is virtually eliminated. Drive belt service life has been considerably increased and maintenance literally eliminated.
