US Motor Works 22319 Thermal Fan Clutch

The US Motor Works 22319 is a thermal fan clutch engineered to regulate engine cooling fan operation for 1981-1985 Mercedes-Benz vehicles. This fan clutch uses a temperature-sensitive bi-metallic coil that engages and disengages the cooling fan based on engine heat, ensuring optimal cooling performance while reducing parasitic power loss and fan noise during normal driving conditions.

Key Features:

• Direct-fit replacement for 1981-1985 Mercedes-Benz applications
• Temperature-activated design engages fan only when additional cooling is needed
• Helps improve fuel efficiency by reducing unnecessary fan drag
• Reduces fan roar and noise when cooling demand is low
• Quality engineered construction for reliable thermal control

This thermal fan clutch is a critical component of your Mercedes-Benz cooling system, automatically modulating fan speed to match cooling requirements. The bi-metallic spring responds to radiator air temperature, increasing fan speed during high-heat conditions and allowing the fan to freewheel when extra cooling isn't necessary.
