Product Details

Gates E-Start Micro-V belts are engineered for belt-driven starter generator stop-start belt drives, where consistent grip and controlled operation matter. This K070415EST serpentine belt follows a K-section profile with 7 ribs and OE Exact sizing, making it a direct-fit replacement for vehicles that use this specific accessory drive configuration. The belt’s EPDM compound and aramid reinforcement help it maintain form and tension characteristics in demanding daily driving conditions. This part cross-references Dayco A070416 for the same application.

Common Issues This Belt Can Address

  • Squealing or chirping from a worn accessory drive belt
  • Cracking, glazing, or rib wear on the existing serpentine belt
  • Inconsistent accessory drive performance in stop-start operation
  • Belt stretch or loss of tension from age and heat cycling
  • Fitment problems when replacing an OE-style E-Start belt

Installation Notes and Tips

Verify the belt section, rib count, and measured length before installation. Confirm routing against the vehicle’s belt path and inspect pulleys, tensioners, and idlers for wear before fitting the new belt. For fitment reference, this part fits 2016-2019 Hyundai Sonata, 2017-2020 Kia Optima, and 2024 Dodge Hornet.
