Abstract
An apparatus for cooling a vehicle engine includes: a combustion chamber in which a piston reciprocates; water jackets in which a coolant flows to cool the combustion chamber; and a cylinder block forming a framework of an engine. In particular, the cylinder block includes: a cylinder block body in which the combustion chamber is formed, and an exhaust gas recirculation (EGR) cooler mounted in the cylinder block body such that the EGR cooler is heat-exchanged with a coolant discharged from the combustion chamber. The cylinder block body is provided with an EGR cooler insertion part, to which a coolant of the combustion chamber is supplied and the EGR cooler is inserted, and the EGR cooler is provided with a gas tube in which an exhaust gas flows. The exhaust gas of the gas tube is cooled by a coolant supplied to the EGR cooler insertion part.
