Caliso 888K5 Poly V Serpentine Belt K-Section - 5-Rib 88.8

The Caliso 888K5 is a K-section Poly V serpentine belt (also known as a Multi-V or micro-rib belt) featuring a 5-rib design with an 88.8-inch pitch length and an outside circumference measurement of approximately 89.55 inches. This belt is engineered as a direct OEM-equivalent replacement for vehicles requiring the industry-standard 888K5 belt designation.

Key Features:

• EPDM rubber construction — heat, ozone, and abrasion resistant for long service life
• Polyester fiber tensile members — provide high modulus, low-stretch performance with superior resistance to fatigue and shock loads
• 5-rib K-section profile — ensures precise belt-to-pulley contact for efficient power transfer
• Fiber-reinforced undercord — improves belt stability and reduces noise from worn or misaligned pulleys
• Oil and chemical resistant — maintains integrity in demanding under-hood environments
• OEM equivalent fit — meets or exceeds original equipment manufacturer specifications

The 888K5 serpentine belt is a critical engine accessory drive component, transferring power from the crankshaft pulley to accessories such as the alternator, power steering pump, air conditioning compressor, and water pump. Replace at the first sign of cracking, fraying, or glazing to prevent unexpected accessory failure.
