Abstract: The subject of the present invention concerns an engine-cooling radiator module assembly (1), an engine block (3), a radiator module (9) and a method for cooling an oil circulating in an oil circuit of an engine by means of a coolant. The coolant runs through a coolant channel which is formed both in the engine block (3) and in the radiator module (9). Parallel to the coolant channel there is a bypass channel (2) through which a partial coolant stream is conducted—parallel to a partial coolant stream flowing through the engine block (3)—to an oil/coolant heat exchanger (8). The radiator module (9) is at least partially integrated in the engine.

Abstract: The invention relates to an oil pan arrangement for an internal-combustion engine including a cover part, a bottom part for the oil pan and at least one suction pipe which opens out into an suction region of the bottom part. The suction pipe is connected to the suction region and the bottom part in one piece manner. The suction region comprises a wall portion which incorporates at least one suction window.
