Specifications

The Horton K9908504 K32 Dual Pilot Rear-Air Fan Clutch provides an air-operated solution for controlling engine cooling fan engagement in compatible commercial vehicles.

The clutch operates using an on/off engagement system that connects or disconnects the cooling fan according to the vehicle's air-control system. Horton designed the K32 dual-pilot platform to consolidate several earlier fan clutch configurations into a serviceable replacement assembly. Its two-piece friction liner arrangement supports maintenance, while available seal and major repair kits provide additional service options.
