Caliso Standard Duty Thermal Engine Cooling Fan Clutch

The Caliso Standard Duty Thermal Engine Cooling Fan Clutch is a replacement engine cooling fan clutch. It controls how fast the radiator fan spins based on underhood temperature. A thermal fan clutch helps the engine warm up and run at a steady temperature. It also reduces the power and noise the fan uses when full airflow isn't needed.

Key Features:

• Thermal operation: A temperature-sensing thermal spring on the front of the clutch responds to heat from the radiator. It engages the fan when more cooling is needed.
• Standard duty design: Built for standard-duty applications that use a thermally controlled, viscous-type fan drive.
• Reduced fan load when cool: The fan is largely disengaged on a cold engine. This supports faster warm-up, lower fan noise and better fuel economy.
• Added cooling when hot: As underhood temperatures rise, the clutch increases fan speed to move more air through the radiator.
• Direct replacement: Intended to replace a worn or failed original fan clutch.

A failing fan clutch can cause overheating, a constantly roaring fan or poor cooling at idle. Replacing it restores proper fan control and helps protect the cooling system. This product line is offered in multiple part numbers, so choose the one cataloged for your application.
