Belt Driven Flex Fan17in - Silver

The Belt Driven Flex Fan 17in - Silver from FLEX-A-LITE is a mechanical cooling fan engineered for vehicles requiring reliable, efficient engine temperature management without electrical complexity. Designed for law enforcement, military, and tactical vehicle operators who depend on mission-critical equipment, this belt-driven fan delivers consistent cooling performance in high-demand applications where parasitic electrical load must be minimized. The 17-inch diameter provides optimal air displacement for mid-size engine compartments while maintaining a compact footprint suitable for custom and retrofit installations.

This six-blade cooling fan features a steel hub paired with stainless steel blades, delivering durability and corrosion resistance essential for harsh operational environments. The 5/8-inch pilot bore accommodates standard engine shaft configurations, while the adjustable 1-3/4 to 2-1/2 inch bolt pattern ensures compatibility across multiple platform applications. Belt-driven operation means the fan runs mechanically without relay dependency—critical redundancy for vehicles operating in remote or austere locations where electrical failures cannot compromise thermal management. The silver finish provides visual consistency with aftermarket cooling system components while protecting against oxidation.

This fan benefits tactical vehicle builders, off-road enthusiasts, and operators maintaining older or custom platforms where electronic cooling control is either unavailable or undesirable. Installation requires proper alignment with the engine's serpentine belt system and verification of clearance in the engine bay—dimensions of 18 x 2.5 x 20 inches should be validated against your specific vehicle platform. The mechanical design eliminates thermostat and sensor calibration concerns, reducing maintenance overhead in field conditions while ensuring immediate cooling engagement proportional to engine speed.
