Abstract: A system including startup, load, flow, and peak estimation modules. The startup module, during a startup period or in response to a startup of the engine, receives a temperature signal and generates a first condition signal. The load module determines a load on the engine and generates a second condition signal. The flow module, if the first condition signal indicates a temperature of the engine is less than a first predetermined temperature and if the second condition signal indicates the load is less than a predetermined threshold, operates a pump to circulate coolant during the startup period. The peak estimation module estimates a temperature of a hottest metal location on the engine. The flow module increases a speed of the pump if the temperature of the hottest metal location is greater than a second predetermined temperature or the load is greater than or equal to the predetermined threshold.
