A governing system of an engine coolant control system in which first and second portions of coolant are pumped from an engine to a regulator and back to the engine and from the engine to a radiator and back to the engine, respectively, is provided. The governing system includes a temperature sensor of the engine to sense coolant temperatures, an ambient temperature sensor of the radiator to sense ambient temperatures, a heating element disposed to heat the first portion of the coolant at one of a location upstream from the regulator and the regulator, a valve operably disposed along a section of piping through which the first portion of the coolant flows from the engine to the regulator and a controller which controls operations of the heating element and the valve in accordance with the readings of the temperature sensor of the engine and the ambient temperature sensor.
