Caliso 845K6 Serpentine Belt 6-Rib 845mm Poly-V PK Belt

The Caliso 845K6 is a heavy-duty 6-rib Poly-V serpentine belt engineered for reliable power transmission in automotive accessory drive systems. Built to K-section (PK profile) standards, this belt measures 845mm in outside length with six longitudinal ribs, delivering efficient, low-slip performance across a wide range of operating conditions.

Poly-V (multi-rib) serpentine belts like the 845K6 are designed to simultaneously drive multiple engine accessories — including the alternator, power steering pump, air conditioning compressor, and water pump — from a single compact belt. The ribbed profile provides maximum surface contact with the pulley grooves, resulting in superior grip and reduced heat buildup compared to traditional V-belts.

Key Features:

• Belt Profile: K-section Poly-V (PK / Multi-Rib / Serpentine)
• Number of Ribs: 6
• Outside Length: 845mm (approximately 33.3 inches)
• Construction: High-strength cord reinforcement with durable rubber compound for heat and wear resistance
• Flex-resistant design for smooth, quiet operation under load
• Oil and heat resistant compound extends service life
• Meets or exceeds OEM specifications for fit and performance

The 845K6 serpentine belt is a direct-fit replacement designed to restore proper accessory drive function. Always verify belt length, rib count, and cross-section profile before installation to ensure compatibility with your specific application.
