Serpentine belts and automatic tensioners more than tripled belt life.
Always first diagnose why the belt needs to be replaced. This video is sponsored by Continental.
It’s critical the pulley is in alignment and the belt is not contaminated. This video is sponsored by Litens.

In this Maintenance Minute, Andrew Markel discusses how even 2mm can mean everything when it comes to belts.
Andrew Markel discusses belts made from modern materials, and how signs of wear and slippage may not be as apparent with a visual inspection.
Andrew Markel discusses belt noise and flutter, and how to inspect the belt, pulleys and tensioners for these issues.
Andrew Markel stresses the importance of a properly aligned belt and high quality gasket after a water pump job to prevent premature rapid wear during operation.
On an engineering level, the design of the accessory belt drive is a balancing act of efficiency, force and vibration. The more contact or wrap a belt has with a pulley, the more force or energy can be transmitted without slipping and the less tension the belt will need. But, this is not great for efficiency because it creates more friction and drag.
