What powers the fan on a 1995 Lexus sc 400?

The fan on a 1995 Lexus SC 400 is powered by the engine's cooling system, specifically by an electric motor. This motor is activated by the engine control unit (ECU) based on the engine temperature and the demands of the air conditioning system. In some cases, a viscous fan clutch may also be used for the mechanical fan, which engages when the engine reaches a certain temperature.
