Abstract
Official abstract text for this publication.
A thermal management module includes a motor with an output shaft, and a gear train connecting the output shaft to a driven gear connected to a valve for controlling coolant flow in a coolant system. At least one grille shutter is movable between an open position allowing air through the grille shutter and a dosed position preventing air through the grille shutter. A linkage connects the at least one grille shutter to the output shaft or the gear train, so that the motor is operable to control a valve operating position of the valve and a shutter operating position of the at least one shutter.
