Caliso Poly V Serpentine Belt K-Section Micro-V

The Caliso Poly V Serpentine Belt line is made up of K-section micro-V belts, also called micro-rib, poly-rib or multi-rib belts. They are replacement belts for automotive accessory drive systems. A single serpentine belt winds around several pulleys. It transfers engine power to accessories such as the alternator, power steering pump, A/C compressor and water pump.

Key Features:

• K-section profile: Multiple narrow V-ribs run along the belt. They combine the flexibility of a flat belt with the grip of a V-belt, so power transfers smoothly and evenly.
• Heat and ozone resistant construction: The EPDM rubber compound is designed for long service life in hot underhood conditions.
• Low-stretch tensile cord: The treated polyester cord helps the belt hold consistent tension over time.
• Quiet operation: Fiber-reinforced rib stock helps reduce noise from worn or misaligned pulleys.
• Flexible design: The belt can run around small-diameter pulleys and tight accessory drive layouts.
• Cross-reference friendly: Each belt corresponds to standard K-section and metric PK belt designations, which makes it easier to match a replacement to the original belt.

Replacing a worn, cracked or glazed serpentine belt helps keep the charging system, steering assist and cooling components running reliably. Each belt in this line is a dependable replacement for passenger car, truck and SUV accessory drives.
