Product Details

Gates Premium OE Micro-V belts are engineered to match OE dimensions and material construction, helping preserve proper belt tracking and accessory drive operation. This K050757 serpentine belt uses an EPDM compound and polyester cord reinforcement, along with a 5-rib K-section profile, to align with the original belt specification used in the listed Saturn applications. For Saturn SC1, SL, SL1, and SW1 models, the belt supports the accessory drive system where accurate length and rib profile are critical.

This part cross-references Bando 5PK1925 for the same application.
