BorgWarner 1090-09650-01 K32 On/Off Fan Clutch

Description

Upgrade your cooling system with this genuine BorgWarner Kysor K32 series fan clutch (Part # 1090-09650-01) — a heavy-duty, OEM-quality solution engineered for high-performance trucks and industrial equipment.

When your engine demands maximum cooling — whether it’s hauling heavy loads, idling in traffic, or powering equipment in hot environments — this fan clutch engages the cooling fan with precision and authority. Unlike standard viscous style clutches, the K32 series is designed for On/Off control, delivering better cooling when needed and quieter operation when not.

This unit is built with rugged steel construction, capable of handling bigger fans at higher RPMs and tougher actuation demands. Whether you operate a Volvo D13, Mack MP8, Cummins ISX15 or similar heavy-duty diesel engine, this part is a trusted fit.

At Centark Parts, we focus on OEM and trusted aftermarket components — so you’ll get a quality product backed by expert support. We inspect and ship nationwide with the reliability you expect.

Fits 2 9/16″ (2.56″) (≈ 65 mm) fan pilot hubs—ideal for high-torque, high-duty cycle applications.

Fitment Note: Be sure to verify your fan-pilot size, mounting bolt pattern and system requirements before installation. A proper match ensures optimal performance and long service life.
