A small block Chevy (SBC) serpentine system comprises a collection of components designed to efficiently drive engine accessories such as the alternator, power steering pump, air conditioning compressor, and water pump using a single, continuous belt. This setup replaces the older V-belt systems, known for their individual belts for each accessory, with a single, multi-groove belt and spring-loaded tensioner.
The implementation of this system offers enhanced efficiency, reduced maintenance, and a cleaner engine bay appearance compared to traditional setups. The single belt design minimizes slippage, leading to more reliable accessory operation and improved overall engine performance. Historically, upgrading to this system was a popular modification for increased reliability and performance and to modernize older engines.
