PROBLEM TO BE SOLVED: To provide an engine cooling device reducing engine component cost and assembling cost by simplifying the construction of a cooling water path from a water pump to a cooling portion of a supply air cooler in an engine having the water pump mounted at the front end to reduce the number of components and assembling manhours for the cooling device. SOLUTION: In the engine having the water pump mounted at the front end, the cooling water path is integrally cast and formed inside a crank case, which is connected to the cooling water outlet of the water pump and connected to the cooling portion while extending to the axial center of the crank.
