The invention provides a control method of an external control type fan clutch able to improve engine performance, fuel cost and cooling performance of a capacitor of an air conditioner (A/C) and restrain fan noises due to associative rotation. Namely, in the external control type fan clutch device constructed so as to control the opening and closing of a supply adjusting hole of oil by a valve member operated by an electromagnet, the opening and closing of the supply adjusting hole of the oil is on-off-controlled with the temperature of a cooling liquid of a radiator, a fan rotating speed, the temperature of transmission oil, a vehicle speed, an engine rotating speed, the pressure of a compressor of the air conditioner, etc. as parameters. |
