ACDelco 97300657 GM Original Equipment V-Ribbed Serpentine Belt

The ACDelco 97300657 is a GM Original Equipment V-Ribbed Serpentine Belt designed, engineered, and tested to rigorous OE standards and backed by General Motors. This direct-fit replacement belt drives multiple engine accessories — including the alternator, power steering pump, and water pump — using a single continuous belt routed through the accessory drive system.

Constructed from EPDM (Ethylene Propylene Diene Monomer) rubber with a reinforcing cord of polyester and aramid, this belt resists hardening, cracking, and glazing far longer than traditional neoprene-based belts. The result is quieter operation, reduced slippage, and a longer service life even under high underhood temperatures or harsh cold-weather starts.

Key Features:

• GM Original Equipment — designed and validated specifically for GM vehicles
• EPDM rubber construction — stays soft and pliable longer than neoprene alternatives
• Polyester and aramid cord reinforcement — resists stretching and maintains consistent tension
• V-ribbed multi-groove design — creates secure pulley contact for reliable traction and minimal slippage
• Broad temperature tolerance — performs reliably from cold winter starts to sustained highway driving
• Black finish — standard OE appearance
• Limited Lifetime Warranty (parts only)

This ACDelco OE serpentine belt is the GM-recommended replacement for worn or failed drive belts, ensuring proper system harmony with your existing tensioner and pulleys for durable, quiet accessory drive performance.
