Caliso 745K6 Poly V Serpentine Belt - 6-Rib 74.5 Inch

The Caliso 745K6 is a K-series Poly V (multi-rib) serpentine belt engineered for reliable performance in automotive accessory drive systems. Measuring 74.5 inches in length with 6 ribs, this belt is designed to drive critical engine accessories including the alternator, water pump, air conditioning compressor, and power steering pump.

Constructed with heat and ozone-resistant EPDM rubber, the 745K6 is built to withstand the demanding thermal and environmental conditions of the modern engine bay. A high-modulus, low-stretch polyester tensile cord provides superior resistance to fatigue and shock loads, while fiber-reinforced rib stock adds stability and helps reduce noise caused by worn or misaligned pulleys.
