• Precision-molded ribs for smooth, quiet operation and reduced vibration
• Engineered for consistent grip and power transfer to accessory drives
• Meets or exceeds original equipment specifications
• Designed for use with standard serpentine belt tensioners and idler pulleys

The Gates 12339 serpentine belt drives critical engine accessories including the alternator, power steering pump, air conditioning compressor, and water pump. Replacing a worn or cracked belt proactively helps prevent unexpected breakdowns and costly repairs. Gates belts undergo rigorous testing to ensure durability and reliability across their full service life.
