    Abstract: A system according to the principles of the present disclosure includes a pump control module, an actuator control module, and a torque reserve module. The pump control module switches a water pump between on and off. The water pump circulates coolant through an engine when the water pump is on. The actuator control module controls a first actuator of the engine based on a first torque request and that controls a second actuator of the engine based on a second torque request. The torque reserve module adjusts a torque reserve before the water pump is switched on or off based on a change in engine load expected when the water pump is switched on or off. The torque reserve is a difference between the first torque request and the second torque request

    Abstract: A system includes a coolant management module that, determines whether an engine of a vehicle is off, determines, in response to a determination that the engine is off, whether a heater associated with the engine is on, receives one of a plurality of engine coolant temperature (ECT) measurements and a respective location associated with the received ECT measurement, and communicates the respective location and an instruction to direct engine coolant flow from the respective location to one of the heater and engine. The system also includes a coolant control module that selectively actuates one or more coolant control valves based on the respective location and the instruction.
