Caliso 22025 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22025 is a heavy-duty thermal engine cooling fan clutch engineered to maintain optimal engine temperatures under a wide range of operating conditions. Designed as a direct-fit replacement, this thermal fan clutch meets or exceeds original equipment specifications for proper fit and reliable performance.

Thermal fan clutches use a bi-metallic spring mounted at the front of the unit to sense underhood temperatures and modulate fan engagement accordingly. When the engine is cold or running at normal operating temperature, the clutch partially disengages the fan to reduce parasitic drag, improve fuel economy, and lower noise levels. As engine temperatures rise, the clutch fully engages the fan to maximize airflow across the radiator and bring temperatures back into the normal range.

Key Features:

• Heavy-duty thermal design for reliable, temperature-responsive fan control
• Direct-fit replacement — engineered to match OE dimensions and mounting specifications
• Bi-metallic thermal spring senses underhood heat for precise clutch engagement
• Reduces engine load and improves fuel efficiency when full cooling is not required
• Minimizes fan noise during normal operating conditions
• Built to meet or exceed original equipment performance standards
• General application coverage, clutch specification, and industry interchange information included on label

The Caliso 22025 heavy-duty thermal fan clutch is a dependable replacement for worn or failed OE fan clutches, restoring proper cooling system function and protecting your engine from overheating.
