Abstract
A method for cooling a motor vehicle engine which engine consists in regulating the volume and the flow rate of a coolant in a hydraulic circuit provided with a first bypass hose wherein is arranged a water/oil exchanger. The method comprises a first step of regulating the flow rate of the liquid in the first bypass hose to increase the speed of the increase in the temperature of the oil and a second step of regulating the flow rate of the liquid in the first bypass hose to maintain the temperature of the oil at about a reference temperature. The invention also concerns a device for cooling a motor vehicle engine.
