Navistar Engine Serial Number Locations

The complete engine serial number (ESN) is stamped on a pad on the side of the cylinder block. For units built prior to model year 2000 the location is on the left hand side of the block just below the cylinder head to cylinder block parting line. For model year 2000 and newer units the serial location was moved to the right side of the cylinder block between the oil cooler and top of the block.

The emission label is located on top of the rocker cover or intake manifold. The engine model, model year, horsepower rating and torque rating can be obtained from this label. This information is required to determine the correct components for most units built post 1993.
