Systems and methods can determine whether an air conditioning (AC) system of the vehicle is being operated under a maximum cooling condition. Responsive to determining that the AC system is being operated under the maximum cooling condition, it can be determined whether vehicle fluid temperatures meet associated predetermined thresholds. If none of the vehicle fluid temperatures meet the associated predetermined thresholds, a heater core valve can be switched to a closed position to reduce a flow rate of the coolant through a heater core. If one or more of the vehicle fluid temperatures meet the associated predetermined thresholds, the heater core valve can be switched to an open position to increase the flow rate of the coolant through the heater core. Such systems can force coolant to flow through the heater core to reduce vehicle fluid temperatures even when the AC system is being operated under the maximum cooling condition.
