Abstract

The present invention provides engine-cooling module assemblies. One engine-cooling assembly includes an engine block and a cooling module including a coolant channel integrated into the engine block. Parallel to the coolant channel is a bypass channel integrated in the engine block and through which a portion of a coolant stream is conducted to an oil/coolant heat exchanger. The present invention also provides a method for cooling oil circulating in an oil circuit of an engine by means of a coolant. The coolant runs through a coolant channel that is formed of both a portion of the engine block and a portion of the cooling module.
