The invention discloses a cooling system and lubricating system integration module for a diesel engine. The cooling system comprises a module shell. An engine oil cooler, an engine oil filter and a water pump are arranged on the module shell. A water way and an oil way are arranged in the module shell. A cylinder block mounting face for being mounted on an engine cylinder block is arranged on the module shell. An oil inlet a and an oil outlet a are formed in the cylinder block mounting face. An inlet check valve is arranged on the oil inlet a. An outlet check valve is arranged on the oil outlet a. In this way, when the engine is shut down, engine oil in the module cannot flow back into the engine cylinder block; and when the engine is started again, it is not necessary to make the module be filled with the engine oil in advance, and the time of the engine oil entering the engine cylinder block is shortened, so that engine movement friction components can be lubricated in time, the operating reliability of the engine is improved, and the service life is prolonged.
