General Description
DESCRIPTIONWhen ignition switch is in On position, system voltage is applied through ignition fuse to radiator fan switch. Fan switch closes when engine coolant temperature reaches 208°F. With fan switch closed, voltage is applied to radiator fan motor. Since the fan motor is permanently grounded, fan operates as soon as voltage is applied. When temperature falls below 199°F, fan switch opens and voltage to fan motor is interrupted.
