  "textContent": "Cooling system for an internal combustion engine (2) coupled to an automatic transmission (3) with integrated hydraulic retarder (3R) which uses the automatic transmission oil to generate an auxiliary braking torque applied to the wheels of the vehicle in which the engine (2) is installed. The cooling system comprises a mechanical pump (5) rotated by the internal combustion engine (2) and adapted to circulate a cooling fluid in a hydraulic circuit (7) and a liquid-air heat exchanger (8). An electric pump (25) is provided, arranged along a by-pass duct (27) to directly supply the cooling fluid coming out of the heat exchanger (8) to the inlet (10-b) of the cooling fluid - automatic transmission (3) oil exchanger. Electronic control means (30) are also provided for controlling the electric motor (32) which operates the electric pump adapted to regulate the rotation speed Ép of the electric pump (25) rotor with reference to the detected rotation speed Ém of the internal combustion engine (2).",
