Drive belts, typically serpentine or V-type, transmit power from the engine’s crankshaft to various accessory drives including the alternator, power steering pump, air conditioning compressor, and water pump. These reinforced rubber components utilize a ribbed or grooved design to maximize contact and minimize slippage within the pulleys. Modern serpentine belts often employ EPDM rubber compounds for durability and resistance to cracking, while older V-belts are constructed with reinforced polyester cords. Tension is maintained via a spring-loaded or hydraulic tensioner to ensure consistent performance and prevent overheating. Proper belt alignment and tension are critical for optimal system function and longevity.
