System and method for regulating coolant flow through a charge air cooler of a vehicle

A system according to the present disclosure includes a coolant flow request module and a pump control module. The coolant flow request module is configured to determine a coolant flow request based on at least one of (i) an outlet temperature of a compressor disposed upstream of a heat exchanger of a charge air cooler, and (ii) an efficiency of a radiator of the charge air cooler. The pump control module is configured to control an output of a pump based on the coolant flow request. The pump circulates coolant through the radiator of the charge air cooler and through the heat exchanger of the charge air cooler when the pump is activated. The heat exchanger is disposed upstream of an intake manifold of an engine.
