When people hear the word "clutch," the first thing that comes to mind is usually the device that allows one to shift from one gear to another with a manual transmission. In fact, a clutch is used for any machine application in which two components are spinning at different rates of speed and need to be synchronized in order for them to connect to each other. Many devices use a clutch, including the wife's washing machine. Another device on your own car that often has a clutch is the cooling fan. By using a Behr Fan Clutch, your cooling fan is no longer tied to a belt-driven pulley that rotates in lockstep with the crankshaft. Basically, a Behr Fan Clutch allows (or forces) your fan to run as fast as it needs to for optimum cooling. It saves on engine power as well - because the fan is no longer operated by the engine itself, there is more power available to actually run the vehicle. The engine no longer needs to waste energy running a fan when not necessary. On the other hand, it kicks on when you punch the accelerator and need extra cooling fast. Try a Behr Fan Clutch today.
