This viscous fan clutch regulates radiator fan blade engagement based on engine temperature, helping balance cooling demand and engine efficiency. A failing clutch may lead to overheating or wasted power under different load conditions.

Built with a sealed fluid coupling and internal thermostatic sensor, it’s designed to withstand vibration, heat, and contaminants common in engine compartments. It’s sold as a direct replacement clutch unit.

• Thermostatic viscous coupling for engine cooling fan module
• Automatically engages fan speed as temperature increases
• Sealed design to guard against leaks and debris intrusion
• Drop-in replacement for original fan clutch assemblies

Installation Tip: Align the clutch precisely with the drive hub before tightening. Reinstall fan blades exactly as removed, torque evenly, and test by running the engine to operating temperature to verify proper engagement.

A dependable replacement unit to restore proper cooling control and support engine performance across varied conditions.
