Abstract
A method of powertrain thermal control in a vehicle having grille airflow shutters. The method comprises the steps of: detecting vehicle operating conditions including at least a temperature condition for an engine cooling loop and engine load; pumping engine coolant through the engine cooling loop including pumping the engine coolant through a radiator under all temperature conditions of the engine cooling loop; and adjusting the grille airflow shutters relative to a grille to selectively block a portion, none or all airflow through the grille to thereby control airflow through the radiator based upon the detected vehicle operating conditions.
