Detailed Product Description
This remanufactured alternator from BBB Industries features a brush-type design cooled by an internal fan, ensuring consistent airflow and heat dissipation during operation. The included decoupler pulley reduces vibration and noise by allowing the pulley to rotate independently from the alternator shaft, which helps extend the life of the belt and related components. With a 5-groove serpentine pulley measuring 2-1/8 inches in diameter, this alternator is engineered to fit specific applications requiring a clockwise rotation and negative polarity electrical system.
The internal voltage regulator maintains a steady 12-volt output, essential for the proper functioning of your vehicle’s electrical system. The plug clock position at 9 o'clock ensures compatibility with the wiring harnesses of Cadillac ATS, CTS, and Chevrolet Acadia and GMC Traverse models.
