Product Description

The Gates K100618HD FleetRunner Micro-V serpentine belt is built for heavy-duty truck and fleet applications. With its 10-rib "K" cross-section, reinforced EPDM rubber construction, and robust build quality, the belt reliably powers accessories - such as alternators, water pumps, fans, and compressors - even under high load, harsh conditions, or continuous operation. Its heavy-duty design resists wear, oil, coolant, ozone, and environmental degradation, making it a dependable choice for long-haul fleets, older diesel trucks, and commercial applications.

Featuring an outside circumference of 62.4 inches (≈ 1585 mm), this belt fits longer-layout accessory-drive systems commonly found on heavy trucks. The reinforced core and strong ribbed profile maintain stable belt tension and minimize stretch or slip, which helps reduce maintenance frequency and increases service life - especially valuable for busy fleets and high-utilization vehicles.

Disclaimer: The vehicle fitment list above is provided for reference only, based on publicly available aftermarket catalog data. Actual compatibility depends heavily on engine variant, accessory-drive configuration, pulley layout, and belt routing. Buyers must verify belt length, rib count, and drive-system setup on their specific vehicle before ordering to ensure proper fit - this belt may not fit all trims or configurations even among the same make/model listed.
