Abstract
A temperature comparison module generates a temperature difference between an engine coolant temperature and a radiator coolant temperature. An energy determination module determines an energy value corresponding to heat energy generated by an engine. The heat energy increases at least one of the engine coolant temperature and the radiator coolant temperature. A diagnostic module generates a comparison of the temperature difference and the energy value and determines a status of a thermostat associated with the engine based on the comparison.
