    The Derale 17917 is a 17" mechanical cooling fan finished in black, designed for reverse-rotation fan-clutch applications found on many serpentine-belt engines. It mounts on a thermal fan clutch so the fan engages for strong airflow when the engine is hot and freewheels when cool, reducing drag, noise, and power loss compared with a fixed fan. It is a universal mechanical fan for reverse (counterclockwise) rotation engines.

    Specifications:

    • Type: mechanical cooling fan for fan-clutch applications
    • Diameter: 17"
    • Rotation: reverse (counterclockwise)
    • Finish: black
    • Mounting: installs on a thermal fan clutch
    • Part number: 17917
