Caliso 22182 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22182 is a heavy duty thermal engine cooling fan clutch designed as a direct-fit replacement for worn or failed original equipment fan clutches. Engineered to meet or exceed OE specifications, this thermal-style clutch delivers reliable, temperature-controlled fan engagement to keep your engine running at its optimal operating temperature.

How It Works:

A thermal fan clutch uses silicone-based viscous fluid and a bi-metallic spring assembly to automatically engage the cooling fan when engine temperatures rise and disengage it once temperatures stabilize. This reduces unnecessary parasitic load on the engine, improving fuel efficiency and reducing fan noise during normal cruising conditions.

Key Features:

• Heavy duty thermal design for demanding cooling requirements
• Silicone fluid-filled clutch chamber for smooth, progressive fan engagement
• Bi-metallic thermal spring responds to underhood temperature changes
• Direct bolt-on replacement — no modification required
• Built to OE fit, form, and function standards
• Cross-Reference Part Numbers: 6601, 130-0197, 1550708, 9502110, 281672, 21082-EA200

Common symptoms of a failing fan clutch include engine overheating at low speeds or idle, excessive fan noise, poor air conditioning performance, and reduced fuel economy. Replacing a worn clutch with the Caliso 22182 restores proper thermal management and protects your engine from heat-related damage.
