Product teams continually seek valuable information for engineering improvements.
To assist in this effort, an engine exchange program will be used for the listed engine and vehicles.
The 2020 model year engine exchange program will be administered by the GM Product Quality
Center (PQC).

Please contact the Product Quality Center (PQC) by opening a new case via Dealer Case Management (DCM) From
the DCM home page, click on “New PQC Case” found on the Technical Assistance tab.
Then in Global Connect click on the Support/Chat tab, TAC-PQC Tab, PQC -Parts Restrictions Templates to
Download the appropriate PQC -Parts Restrictions Template and save a copy to your computer, You can attach a
copy of the template to your PQC Case.
Note: (Do Not clear any DTCs prior to contacting the PQC).

Guidelines for honoring exchange requests underthis program are being strictly enforced.
The PQC may refer the dealer technician to TAC if additional diagnosis is required.

TAC will be available for product inquiries that do not require assembly replacement.

Components that may be removed and serviced without exchange are identified by an "X" in the
appropriate column of the table below
.
Any repairs involving engine components not identified in the table below
, engine noise concerns,
oil consumption, or relatedsymptoms may require an engine exchange.
Important: Engine block and internal components along with any component in which a cylinder
head has to be removed to perform the repair will require an engine exchange.
Please note that this list is subject to change as the program progresses.
You will be notified by the PQC consultant if additional items are considered serviceable on a
particular engine.

Note: The above service parts list of components will be requested through the
normal GM Parts return process for engineering evaluation for cause, through the
WPC parts return process.
Important: Engine repairs or failures that are caused by components external to the engine do NOT
fall under the exchange program. F
or example, if an engine failure is caused by incorrectly installed
engine coolant lines, the engine assembly (or parts required to complete
a repair) must be obtained
from General Motors Customer Care and Aftersales (GMCC&A) through the normal parts ordering
process. The exchange program is created as a wa
y to correct internal concerns and to tak
e what is
learned and find a way to eliminate these concerns. External components causing a failure do not
provide any useful information in improving an engine.The engine received from GMCC&A through
the normal parts ordering process will be a new service engine.
Engine Broadcast Code Location
6.2L Engine Assembly (RPO LT2)

Broadcast Label Shown on the front of engine.

1) Is located on the back of the left cylinder head

2) Is located on the front right side of the engine

Procedures:
A thorough diagnosis must be performed on the condition in order to prevent unnecessary
component replacements.
Contact the Product Quality Center (PQC) to verify the proper diagnosis has been performed.

For effective engineering analysis, please do not remove any components.
Dress items on the removed unit must remain the same as the replacement engine (e.g., exhaust

partially disassembled will be judged as violating this procedure
and, as such, will be billed for all
materials furnished.
Notice: The exchange unit will be shipped with a quantity of oil; check oil level before starting the
