Caliso 22612 Thermal Truck Drive Fan Clutch

The Caliso 22612 is a thermal truck drive fan clutch designed to deliver reliable, temperature-responsive engine cooling for heavy-duty truck applications. The thermal fan clutch automatically engages and disengages based on underhood temperatures, helping maintain optimal engine operating temperature while reducing unnecessary load on the engine.

Using a silicone fluid and thermally actuated spring mechanism, this fan clutch engages the cooling fan when high temperatures are detected and allows the fan to partially disengage during cooler operating conditions — improving fuel efficiency and reducing engine strain.

Key Features:

• Thermal activation responds to underhood and radiator air temperatures for on-demand cooling
• Truck drive design engineered for heavy-duty applications and higher torque demands
• Silicone fluid coupling provides smooth, controlled fan engagement and disengagement
• Meets or exceeds OEM fit, form, and function specifications
• Designed as a direct OEM replacement for a simplified installation
• Helps improve fuel economy when full fan engagement is not required

The Caliso 22612 thermal fan clutch is a dependable OEM-replacement component for maintaining proper engine cooling performance in trucks and commercial vehicles.
