Abstract
A method of controlling cooling flow through a coolant system of an internal combustion engine having an electronic control module, a cooling throttle, an EGR cooler, and an interstage cooler is provided. A pressure within a coolant system is determined. A temperature within the coolant system is determined. A temperature of exhaust gas exiting an EGR cooler is determined. A temperature of intake air exiting an interstage cooler is determined. A position of a cooling throttle within the coolant system is adjusted based upon at least one of the determined pressure within the coolant system, temperature within the coolant system, temperature of exhaust gas exiting the EGR cooler, and temperature of intake air exiting an interstage cooler being above respective predefined thresholds to adjust fluid flow within the coolant system.
