Abstract
An engine compartment cooling fan provided in an engine compartment is controlled by a control unit, to be placed in its ON or OFF state, on the basis of an output from an engine compartment temperature sensor. The control unit continues the control of the engine compartment fan for a predetermined period of time after a key switch is turned off, with power supplied from a battery through a by-pass line. This permits the engine to be re-started without difficulty even after a short time of stop of the vehicle. Upon lapse of the predetermined time, the control unit disconnects the power supply through the by-pass line and stops its operation. Since there is no power consumption after the end of the operation of the cooling fan, unnecessary consumption of the battery can be avoided.
