Beschreibung
Zusammenfassung:	A temperature control system for an internal combustion engine, to which a block heater for warming a coolant and keeping the coolant warm is attachable, the temperature control system includes a coolant circulating apparatus circulating the coolant, a fluid temperature detecting device detecting a fluid temperature of the coolant, a block heater disuse estimating portion estimating a possibility of disuse of the block heater under a condition that a circulation of the coolant is stopped, and a block heater usage determining portion determining whether or not the block heater is used on the basis of changes in the fluid temperature under a condition that the coolant is circulated in a case where the block heater disuse estimating portion does not estimate the disuse of the block heater.
