Product Details

Gates Premium OE Micro-V Belt K061177 is engineered to match OE size, construction, and materials for accessory drive systems that rely on precise belt routing and consistent tension. The K-section profile and 6-rib layout support proper engagement across the pulleys, while the EPDM compound is selected for modern serpentine belt service. This makes the K061177 a direct-fit replacement choice for Chevrolet Express and GMC Savana vans, as well as select Chevrolet Silverado and GMC Sierra heavy-duty trucks listed in the fitment data.

This part cross-references Bando 6PK2995 for the same application.

What It Helps Address

• Squealing or chirping from a worn serpentine belt
• Cracking, glazing, or rib wear on the accessory drive belt
• Loss of alternator drive due to belt stretch or damage
• Improper belt fit on OE-style 6-rib routing
• Accessory drive noise on Chevrolet Express, GMC Savana, Silverado, and Sierra applications

Installation Notes and Tips

Verify pulley routing, rib count, and belt length before installation. This belt is listed for vehicles equipped with a single alternator on Express and Savana applications, and for 2002-2005 Silverado and Sierra models with a 105A alternator and without V.P. Confirm the existing belt number and accessory configuration against the vehicle before service. Inspect tensioners, idlers, and pulley alignment at the same time to help prevent premature belt wear.

Quality Assurance

Gates builds the Premium OE Micro-V Belt line to OE-size and OE-material standards for factory-style replacement performance. The K061177 is specified as an OE-performance belt for the listed Chevrolet and GMC applications.
