A grille shutter actuation system for a vehicle includes a grille shutter, a linear actuator having a cylinder with first and second orifices and a piston. The piston is connected to the grille shutter for moving same. Fluid is pumped into one of the orifices through first or second hoses for moving the piston. A bi-directional motor is connected to the pump, and a controller controls a direction of rotation of a motor shaft in response to an input. A control module provides the input to the controller which determines whether fluid is pumped into the first or second orifice dependent upon the direction of rotation of the shaft. The input is determined by the control module based on information from the controller and/or a sensor associated with the grille shutter. The pump and motor may be remotely mounted within an engine compartment, for example, a distance from the linear actuator(s).
