Detailed Description

The Gates Accessory Belt Drive Kit line is built to simplify full serpentine drive service by addressing the belt and related wear components together. Replacing the belt without servicing the tensioner and idler pulley can shorten belt life and leave worn front-end accessory parts in place. Gates 90K-38112A is engineered for the listed Saturn SC2, SL2, and SW2 fitments and follows the OE-style component layout for a direct repair approach.

This part cross-references Continental K49212A for the same application. Use Gates 90K-38112A when searching for a Saturn SC2 serpentine belt drive kit, Saturn SL2 accessory belt drive kit, or Saturn SW2 belt, tensioner, and idler pulley service solution.

What It Helps Address

  • Squealing or noisy serpentine belt operation
  • Visible belt wear, cracking, or glazing
  • Weak or inconsistent belt tension
  • Idler pulley roughness or bearing noise
  • Front accessory drive service on Saturn SC2, SL2, and SW2 models

Installation Notes and Tips

Verify the vehicle’s year, model, and air conditioning configuration before installation. Match the belt routing and component part numbers to the existing system, and inspect adjacent accessory drive components for wear while the belt drive is apart. The included installation instructions and tech tips support accurate installation on the listed applications.

Quality Assurance

Gates positions this kit as a complete serpentine service solution using OE-equivalent components and application-specific hardware selection for the listed fitments. The goal is to restore the accessory belt drive system with matched parts rather than replacing the belt alone.
