Abstract
A motor-vehicle is provided with an auxiliary cooling system, having a low temperature cooling liquid, entirely independent from the cooling circuit of the engine and including a radiator located at the front part of the motor-vehicle facing the radiator of the cooling circuit of the engine. The auxiliary cooling circuit comprises one or more auxiliary radiators which are connected parallel to the radiator of the auxiliary circuit and which are constituted by motor-vehicle body components.
