19in Fan Clutch Fan Standard Rotation

The DERALE 19in Fan Clutch Fan Standard Rotation is a mechanical cooling fan engineered to maintain optimal engine temperatures through thermostatic engagement. This 19-inch, 6-blade clutch fan operates on standard rotation, making it a direct replacement for OEM cooling systems in light-duty trucks, SUVs, and performance vehicles where precision temperature control is essential. The clutch mechanism engages automatically as coolant temperature rises, drawing maximum airflow only when needed—reducing parasitic load on the engine and improving fuel economy during normal operating conditions.

Built with steel construction and finished in durable black paint, this DERALE unit weighs 5.45 pounds and is designed to fit standard fan shroud configurations. The 6-blade design balances airflow efficiency with noise reduction—a critical consideration for street and off-road applications where engine bay acoustics matter. The thermostatic clutch engages progressively rather than locking in solid, which extends bearing life and reduces wear on the water pump compared to older fixed-blade designs. Standard rotation (clockwise from front) makes this a universal fit for most domestic and import platforms without requiring reverse-rotation variants.

This fan clutch is ideal for builders and enthusiasts upgrading aging cooling systems, restoring classic vehicles, or addressing overheating issues in modified engines. Those running higher-output alternators, intercoolers, or tighter engine bays often encounter stock fan inadequacy; the DERALE 19-inch clutch fan addresses airflow demands without the constant cooling drag of mechanical fans locked in full-speed rotation. The part is commonly selected for engine swaps, supercharger builds, and high-altitude applications where thinner air requires increased radiator airflow.

DERALE is recognized for precision thermal management products. This 19-inch fan clutch represents a middle-ground solution—more efficient than fixed fans, more affordable than electric fan conversions, and proven reliable in daily-driven and competition vehicles. Verify your shroud mounting diameter and fan blade clearance before ordering to ensure fitment with your specific application.
