Caliso 22135 Heavy Duty Thermal Fan Clutch Engine Cooling

The Caliso 22135 is a heavy-duty thermal fan clutch designed as a direct-fit replacement for the original equipment cooling fan clutch. This thermal-style clutch uses temperature-sensitive bimetallic springs and silicone-based fluid to automatically engage and disengage the engine cooling fan based on underhood temperatures, helping maintain optimal engine operating temperature while reducing unnecessary parasitic load on the engine.

Key Features:

• Thermal engagement: Automatically engages the fan when engine temperatures rise and disengages once temperatures stabilize, improving fuel efficiency and reducing noise
• Counter-clockwise (reverse) rotation to match original equipment specifications
• Coil spring type with 4-bolt mounting pattern
• Flange diameter: 1.44 in. | Bolt circle diameter: 6 in. | Thread diameter: M6x1.0
• Includes fan mounting hardware (4 bolts and 4 washers)
• Sold individually
