ABSTRACT:
In order to predict a system malfunction which will lead to overheat and thermal damage of the engine the operation of a level sensor which controls the level of coolant in the coolant jacket of the engine is monitored and in the event that frequency or the time for which the level sensor indicates a low level, falls outside of a predetermine range which defines malfunction free operation, a warning of impending engine overheat or the like is issued.
