Caliso 22172 Heavy Duty Thermal Fan Clutch

The Caliso 22172 Heavy Duty Thermal Fan Clutch is a precision-engineered engine cooling component designed for demanding commercial and heavy-duty vehicle applications. The thermal fan clutch automatically regulates cooling fan engagement based on engine temperature, reducing parasitic power loss and improving fuel efficiency when full cooling capacity is not required.

Key Features:

• Thermal sensing operation — engages and disengages the fan automatically in response to engine bay temperature
• Heavy-duty construction — built to withstand the rigors of high-load, high-cycle commercial and fleet applications
• Direct-fit replacement — designed to meet or exceed OEM specifications for proper fitment and reliable performance
• Reduced engine load — disengages at operating temperature to minimize power draw and improve fuel economy
• Durable internal components — high-quality bearings and fluid coupling designed for extended service life

The Caliso 22172 thermal fan clutch is an ideal OEM-quality replacement for worn or failed fan clutches, helping restore proper engine cooling performance and prevent overheating in heavy-duty service environments.
