Abstract
A device for controlling opening of a cooling circuit control valve system of an internal combustion engine, containing a coolant, which is automatically opened under effect of a cooling liquid being heated to a standard temperature. The control performs an early controlled opening of the control valve system of a cooling circuit located upstream of a heat exchanger before the temperature of the cooling liquid reaches a set temperature value for activating the opening of the control valve system, which is itself lower than the standard temperature, the controlled opening being performed only when the control valve system is first opened.
