Abstract

An engine assembly includes a turbocharger and a fluid conduit. The fluid conduit is thermally coupled to the turbocharger such that the coolant flowing through the fluid conduit can extract heat from the turbocharger. The engine assembly includes a surge tank and an engine head defining a coolant gallery. Further, the engine assembly includes an exhaust manifold integrated with the engine head. The coolant gallery is thermally coupled to the exhaust manifold such that the coolant can extract heat from the exhaust manifold. The engine assembly further includes a coolant manifold in fluid communication with the fluid conduit and the coolant gallery. The coolant manifold defines a venting orifice in fluid communication with the surge tank. Further, the coolant manifold defines a joint passageway in fluid communication with the fluid conduit. Moreover, the coolant manifold defines an interconnection passageway fluidly interconnecting the joint passageway and the coolant gallery.
