Abstract
A method for cooling a motor vehicle engine consists in regulating the volume and the flow rate of a coolant fluid in a hydraulic circuit provided with a degassing bypass hose equipped with an electronically controlled proportional actuator and with means forming direct return of fluid or bypass. The method comprises a step of determining the temperature of the cooling liquid, a step of comparing the temperature of the cooling liquid with a first and second threshold temperature, and a step of controlling the opening of the actuator such that, when the fluid temperature is between the first and the second threshold temperatures, the degree at which the actuator is opened is at least temporarily proportional to the cooling fluid temperature. The invention also concerns a device for cooling a motor vehicle engine.
