Fan Clutch (Viscous Fan Coupling) for Volvo 240 B21, B23, B230, 740, 760, 780, 940 B230 – 122 mm

Fan Clutch (Viscous Fan Coupling) for Volvo 240 B21, B23, B230, 740, 760, 780, 940 B230 – 122 mm

Fan clutch, also known as a viscous fan coupling, for Volvo 240 with B21, B23 and B230 engines, and Volvo 740, 760, 780 and 940 with B230 engines.

The fan clutch regulates the cooling fan speed according to the engine's cooling requirements and helps maintain a consistent operating temperature.

The viscous fan coupling is temperature-controlled and adjusts the fan speed according to the temperature of the air passing through the radiator. As cooling demand increases, the coupling transfers more power to the fan. When less cooling is required, the fan can rotate more slowly, reducing unnecessary fan noise and power consumption.

A worn fan clutch can cause reduced cooling performance, particularly when idling or driving at low speeds.
