A piston assembly includes at least one connecting rod comprising at least one wall that defines at least one first cooling fluid passage within the connecting rod. At least one piston body with at least one wall is coupled to the connecting rod. The piston body wall define at least one second cooling fluid passage within the piston body that is coupled in flow communication with the first cooling fluid passage. At least one piston pin is positioned within the second cooling fluid passage and is coupled to at least a portion of the connecting rod and at least a portion of the piston body. At least one piston crown including at least one wall having at least one third cooling fluid passage is coupled to the piston body. The third cooling fluid passage is coupled in flow communication with the second cooling fluid passage.
