Abstract
A method for preventing an engine overheat based on a coolant temperature applied to an engine systemis provided, in which a controllerchecks if a coolant coming from an engineis distributed to any one of a heater coreB and an ATF warmerA as a radiatoris switched from a distribution blocking state (i.e., radiator closed) at a diagnosis start to a distribution state (i.e., radiator open) during the diagnosis under the control of an opening degree of an ITM valve, diagnoses lack of a coolant amount using factors B determined by an inlet/outlet coolant temperature difference T of the enginethrough first and second water temperature sensorsA andB as a factor cumulative value A, and then controls the ITM valveto a full open state in a state where a coolant temperature increase is predicted.
