Abstract: A coolant collector bracket including a front side, a back side, and a top side is provided. The back side is opposite the front side and includes a plurality of coolant inlets for receiving coolant from a cylinder head. The top side includes an exhaust gas recirculation (EGR) cooler inlet and an EGR coolant outlet. The EGR coolant inlet and the EGR coolant outlet are substantially orthogonal to the plurality of coolant inlets.

Abstract: An internal combustion engine system including a cylinder block, a cylinder head attached to the cylinder block, an EGR cooler, and a coolant collector bracket configured to vertically support the EGR cooler is provided. The cylinder head includes a lateral surface including a plurality of fasteners positioned along a bottom edge of the lateral surface. The cylinder head also includes a plurality of coolant passages. The coolant collector bracket is horizontally coupled to the cylinder head and perpendicularly coupled to the EGR cooler. The coolant collector bracket includes a plurality of mounting legs directly coupled to the lateral surface of the cylinder head. The plurality of mounting legs include a plurality of slots. The plurality of mounting legs are slidably inserted onto the plurality of fasteners of the cylinder head via the plurality of slots.
