Caliso 22613 Heavy Duty Thermal Truck Drive Fan Clutch

The Caliso 22613 is a heavy-duty thermal truck drive fan clutch engineered to deliver reliable engine cooling performance in demanding truck and commercial vehicle applications. This thermally activated fan clutch automatically engages and disengages the radiator cooling fan based on engine temperature, optimizing cooling efficiency while reducing unnecessary parasitic load on the engine.

Key Features:

• Thermal activation — engages the fan at elevated temperatures for active cooling and disengages at normal operating temps to reduce drag
• Heavy-duty construction — built to meet or exceed OEM specifications for durability in truck and commercial use
• Counter-clockwise rotation — correct directional engagement for intended applications
• Direct-fit replacement — designed as a drop-in OEM-style replacement requiring no modification
• Includes mounting hardware — comes with necessary fan mounting hardware for installation
• Industry interchange information — cross-references to OEM and competing part numbers for easy identification

Cross-reference part numbers include Hayden 2839, GM 6008664, and GM 6009791. The Caliso 22613 thermal fan clutch is a cost-effective solution to restore proper engine cooling and prevent overheating in trucks and commercial vehicles.
