Detailed Description

Dayco 5080660 is a serpentine belt engineered for accessory drive system service where correct belt length, rib count, and profile are critical. Its EPDM rubber construction helps resist heat and wear, while aramid reinforcement adds strength for high-load operation. This makes it a practical choice for supercharger-driven setups that require stable belt tracking and consistent grip.

What This Belt Helps Address

  • Belt squeal from wear, glazing, or loss of tension
  • Cracking or fraying on an aging accessory drive belt
  • Incorrect belt length on supercharger-equipped Cadillac CTS models
  • Reduced accessory drive performance caused by rib wear
  • Heat-related belt deterioration in demanding engine compartments

Installation Notes and Tips

Verify belt routing, rib count, and effective length before installation. Confirm supercharger application details for your Cadillac CTS, since fitment is specific to the listed model years and position. Inspect pulleys, tensioners, and idlers for wear before installing the new belt to help maintain proper tracking and service life.

Quality Assurance

Dayco manufactures accessory drive components to meet SAE J1459 and SAE J2432 standards. The 5080660 belt uses EPDM and aramid reinforcement for strength and temperature resistance in automotive belt drive service.
