Q: What is a fan clutch?
A: A fan clutch is an intelligent thermostatic or electronically controlled device mounted between the engine fan and its drive source (e.g., the water pump pulley). Its core function is to automatically engage, disengage, or modulate the speed of the cooling fan based on the engine's cooling demands, thereby optimizing the engine's thermal management efficiency.

Q: What is the main purpose of a fan clutch?
A: Its primary purposes are fourfold: 1) Save energy and reduce fuel consumption by minimizing unnecessary fan rotation; 2) Help the engine warm up faster, reducing cold-start wear; 3) Provide powerful cooling on demand to prevent engine overheating; 4) Reduce fan operating noise, improving comfort.

Q: How does a viscous (silicone fluid) fan clutch work?
A: Its core components are silicone fluid and a bimetallic thermal spring. When the engine is cold, the spring contracts, a valve opens, the silicone fluid is stored in a reservoir, the clutch slips, and the fan spins slowly. When the engine is hot, hot air from the radiator causes the spring to expand, closing the valve and trapping the fluid in the main working chamber. The shear force generated by the fluid's viscosity transmits power to the fan, causing it to spin at high speed.

Q: How is an electromagnetic fan clutch different from a viscous one?
A: The electromagnetic type is controlled by the engine's computer (ECU) based on signals from temperature sensors. The ECU sends on/off commands to an electromagnetic coil, which creates or eliminates a magnetic field to engage or disengage the clutch. It offers more precise control and faster response but is more expensive and complex.

Q: What is the difference between "normally engaged" and "normally disengaged" fan clutters?
A: Normally Engaged: The clutch is engaged (fan on) when power is off; it disengages when powered. Often used in machinery where safety is paramount. Normally Disengaged: The clutch is disengaged (fan off) when power is off; it engages when powered. This is the most common type for energy saving.
