Product Line Details

For vehicles with accessory drive systems sensitive to belt noise and vibration, the aramid tensile cord helps preserve the OE operating characteristics while maintaining the correct fit and belt profile.

Detailed Description

The Gates K050476A serpentine belt is made for accessory drive systems that specify a K-section, 5-rib belt with aramid cord reinforcement. Gates works with OE manufacturers to develop belt-drive solutions that align with factory requirements, and this part follows that approach for a direct OE-style replacement. It is a strong match for drivers searching for a 2020-2026 Buick Encore GX serpentine belt, a 2021-2025 Chevrolet Trailblazer belt, or a 2024-2025 Chevrolet Trax accessory drive belt.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Squealing or chirping from a worn serpentine belt
• Noise and vibration in the accessory drive system
• Cracking, glazing, or wear on an aging belt
• Loss of proper belt tension or belt tracking
• Replacement needs for OE-specified aramid cord belt applications

Installation Notes and Tips

Verify the belt length, rib count, and profile against the original belt before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life and create noise. Confirm fitment by vehicle year, make, and model before ordering the Gates K050476A.
