Caliso 22085 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22085 is a heavy duty thermal engine cooling fan clutch engineered to meet or exceed original equipment specifications. Designed as a direct-fit replacement, this viscous thermal fan clutch precisely controls radiator fan engagement based on underhood temperature, helping maintain optimal engine operating temperatures while minimizing unnecessary power draw.

This thermal fan clutch uses a bi-metallic thermal spring mounted at the front of the clutch body to sense underhood temperatures and modulate fan speed accordingly. When the engine is cold or cruising at highway speeds, the clutch partially disengages to reduce parasitic drag and improve fuel economy. As engine heat increases, the clutch progressively engages the fan to deliver maximum airflow to the radiator.

Key Features:

• Heavy duty thermal design for superior cooling performance
• Standard clockwise rotation
• 4-bolt mounting flange for secure installation
• Flange diameter: 2.87 in. / Bolt circle diameter: 5.35 in.
• Thread diameter: M6 x 1.0
• Hardware included: 4 bolts, 4 nuts, 4 washers
• Engineered to meet or exceed OEM performance specifications

Replace a worn or failed fan clutch promptly — a failing clutch can cause engine overheating, poor A/C performance at idle, excessive fan noise, or reduced fuel economy.
