The DERALE 17-inch Fan Clutch Fan (part number 17117) is a mechanical cooling fan engineered for reliable thermal management in high-demand applications. This standard-rotation unit features a 6-blade design paired with dual clutch bolt pattern compatibility, delivering consistent airflow control without electronic complexity. The black powder-coated steel construction resists corrosion and withstands prolonged exposure to engine heat, making it a proven solution for vehicles requiring dependable cooling performance across varied operating conditions.
Mechanical fan clutches operate on thermal principles—engaging and disengaging based on engine temperature rather than electric signals. The DERALE 17117's dual-bolt pattern accommodates a wider range of engine configurations, simplifying installation across different platforms. At 5.05 lbs, the assembly remains lightweight while maintaining structural integrity under sustained thermal cycling. The 6-blade configuration balances airflow volume with power draw efficiency, reducing parasitic drag on the engine during normal driving while providing rapid cooling capacity when needed. The steel construction with black powder coat finish delivers durability in underhood environments where salt spray, oil mist, and temperature extremes are constants.
This cooling fan is suited for operators and enthusiasts maintaining heavy-duty vehicles, off-road platforms, and older model trucks where factory cooling systems require reinforcement or replacement. The mechanical clutch design is preferred in applications where electrical integration is minimal or where passive thermal response is desired. Whether managing cooling demands during sustained towing, off-road operation, or high-ambient-temperature environments, the DERALE 17117 delivers straightforward thermal management without sensors or electronic failure points.
The 17-inch diameter positions this fan in the mid-to-large range for light and medium-duty cooling applications. DERALE cooling fans are established OEM and aftermarket solutions recognized for longevity in both street and off-road service. The standard rotation direction suits most conventional engine configurations. Verify dual-bolt compatibility with your specific engine block before ordering to ensure proper fitment.
