Abstract
A device for regulating the cooling of a motor-vehicle internal-combustion engine has a fluid-cooling circuit coupled to a fluid pump feeding an installation for heating and/or air conditioning the passenger compartment of the vehicle, with adjustable air-heating parameters, including an air heater. It also has a device for establishing an engine-starting state on the basis of chosen conditions and a device which acts in this starting state for either stopping the pump if the heating demand is below a certain threshold or else for driving the pump as a function of a saturation rotational speed.
