Accessory drive systems rely on components like the Bando Serpentine Belt to transfer rotation from the crankshaft to multiple engine-driven parts. This 4PK960 belt follows a defined routing path across pulleys, turning systems such as the alternator and water pump. Proper belt alignment and tension keep those components moving together as the engine runs. A worn belt can disrupt that connection and affect accessory function. For systems that depend on steady rotation across multiple accessories, the Bando 4PK960 keeps the drive path active.
