retailers how to find engine and automatic
transmission/transaxle identification information for
OEM built service engines, manufactured for GM
service engines, and re-manufactured for GM service
engines.
OEM Identification Information
The engine bar code tag is usually in one of several
places. The bar code tag could be on a rocker arm
cover, the ends of a cylinder head or on the oil pan or
the oil rail area of the engine. The information required
from the tag is the 3 position alpha-numeric code which
identifies the model of the engine and the series of
numbers at the bottom of the tag. The number of digits
will vary depending on the engine application. All the
numbers will be required to process an engine request.

If this is the original engine in the vehicle, the engine
information is available in IVH (Investigate Vehicle
History). Choose the Vehicle Component selection, the
3 position alpha-numeric code is the Part/Num
Broadcast section and the Traceability section is the
bar code information that is required. It may be easier
to use IVH (Investigate Vehicle History) to obtain the
necessary information; however, it is only valid for the
original engine.
All original equipment identification information is also
available in SI. To easily find the information for the
vehicle line you are working on, select the vehicle type
and type the word “identification” in the search box.
This search (described below) will provide the list of the
different assemblies to choose from.

If piston replacement is required, be sure to measure
the cylinder before ordering a piston. The majority of
these engines have oversized cylinders and oversized
pistons ring packs are not available for service. Refer to
SI for the engine you are working on.
If crankshaft bearing replacement is required, be sure
to measure a crankshaft before ordering bearings. If the
crankshaft has been turned, it will require replacement
with all new standard size bearings and crankshaft.
Refer to SI for the engine you are working on.
When determining if a repair should be performed on a
remanufactured for GM engine, contact TAC to discuss
parts availability.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
