An exhaust gas recirculation (EGR) cooler apparatus for a vehicle mounted at a receiving space formed on one side wall surface of a cylinder block of the vehicle, the apparatus comprising:

a housing forming the receiving space, wherein a coolant inflow hole and a coolant exhaust hole are respectively formed to the housing so that a coolant of the cylinder block flows in and out therethrough;
a cover plate mounted on the housing so as to close the receiving space, wherein an exhaust gas inflow hole and an exhaust gas outflow hole are respectively formed to the cover plate so that an exhaust gas flows in and out therethrough;
a core including side caps in which a penetration hole connected to the exhaust gas inflow hole and the exhaust gas outflow hole respectively in the receiving space and a tube connecting the side caps wherein the exhaust gas fluidically-communicates through the tube;
and
a connector respectively connecting the penetration hole of the side caps to the exhaust gas inflow hole and the exhaust gas outflow hole of the cover plate.
