6.4L Power Stroke Engine Serial Number Location
The serial number for a 6.4L Power Stroke engine is located on a half moon shaped section of the engine block on the driver’s side, rear of the engine. A sticker that is applied during production will need to be removed in order to see the serial number. The first two digits will read “6.4”, followed by a four digit manufacturing designator (HU2Y for engines built in Huntsville, AL and HU2U for engines built in Indianapolis, IN), and the final 7 digits are the sequential build number. The same information is also available on the front of the engine, on a sticker mounted on the EGR cooler. Here you will find the plant at which the engine was produced as well as the build number (build number is the last 7 digits of the number posted just above the lower bar code).
