Abstract
A method of monitoring an engine coolant system includes modeling the total energy stored within an engine coolant. If an actual temperature of the engine coolant is below a minimum target temperature, the modeled total energy stored within the energy coolant is compared to a maximum stored energy limit to determine if sufficient energy exists within the engine coolant to heat the engine coolant to a temperature equal to or greater than the minimum target temperature. The engine coolant system fails the diagnostic check when the modeled total energy stored within the energy coolant is greater than the maximum stored energy limit, and the minimum target temperature has not been reached.
