Abstract: Systems and methods are disclosed for determining a temperature of a coolant in a cooling system for an engine and diagnosing a thermostat in the engine responsive to the determined temperature. A system includes a liquid cooling system including a thermostat, the liquid cooling system structured to circulate a coolant, and a controller coupled to the liquid cooling system and the EGR system. The controller is structured to: receive engine heat data indicative of a first amount of heat introduced into an engine; receive heat loss data indicative of an amount of heat loss experienced by the coolant; determine a temperature of the coolant based on the first amount of heat and the amount of heat loss; compare the determined temperature of the coolant to a sensed temperature of the coolant; and determine a status of the thermostat responsive to the comparison.
