ACDelco V-Ribbed Serpentine Belt 12626076 — GM OE fit, multi-accessory drive, durable ribbed grip

ACDelco GM Original Equipment 12626076 is a V-ribbed serpentine belt engineered and validated by GM to drive multiple engine accessories reliably using one continuous belt.

This serpentine belt replaces multiple older belts with a single ribbed unit designed to maintain consistent traction across pulleys for accessories such as the alternator, power steering pump, air conditioning compressor, and water pump. As a GM Original Equipment part, the 12626076 belt is designed, engineered, and tested to meet the specifications General Motors requires for fit, durability, and compatibility with your Chevrolet, Buick, GMC, or Cadillac vehicle.

How does this belt work to run my car's accessories?

The V-ribbed serpentine layout uses a wide, ribbed surface to increase contact with accessory pulleys so a single belt can transfer torque to several driven components. Its multi-rib profile reduces slippage and distributes load evenly, which helps maintain accessory operation even under varied engine loads.

• Single-belt design drives alternator, A/C compressor, power steering, and more
• Ribbed contact surface improves grip and reduces belt chatter
• Engineered for correct width and rib pattern to match OEM pulleys

What makes this an OE (original equipment) replacement?

ACDelco GM Original Equipment belts are either the same parts used during vehicle assembly or parts validated by GM engineers to meet the same standards. That validation covers dimensions, materials, and performance characteristics so the part integrates with vehicle systems as intended.

• Designed and validated by GM engineering for fit and function
• Manufactured to match GM service part specifications
• May replace parts formerly listed as GM Genuine Parts or ACDelco Professional

How long should I expect this serpentine belt to last?

Service life depends on driving conditions, climate, and maintenance, but OE belts are built to provide long, reliable service when installed correctly. Regular inspection for cracking, glazing, fraying, or rib separation helps determine when replacement is needed before accessory performance is affected.

• Inspect belts every oil change or at least twice yearly
• Replace if visible cracking, rib damage, or excessive wear appears
• Keep pulleys and tensioners in good condition to extend belt life
