IMPORTANT: The depth to which the plug is pressed beyond the counterbore may vary. As long as the counterbore
line is visible as indicated above, no further action is required.
3.

Inspect the oil pan pickup tube plug.
a.

If the plug is pressed to a point where the counterbore line is visible (indicated by white arrow above) no
further action is required. Proceed to step 6.

b.

If the plug is NOT pressed deep enough to expose the counterbore line, proceed to the next step.

6860568
Important: Do NOT press the plug in too far. You want to put some pressure on it, stop and check the depth, and
then repeat, doing this as many times as necessary until you have achieved the appropriate depth. It may not
feel like the plug is moving at all, but it will be.
4.

Using a ½ to 3/8 adapter, an appropriate length extension, and a socket on the other end of the extension as shown,
use a prybar to carefully press the plug further into the oil pan, frequently checking the depth to ensure you are not
pressing it in too far.
a.

Use a sharpie or some painters tape to make a mark 12mm (1/2 inch) from the end of the ½ to 3/8
adapter. This will alert you to when the plug is pressed in about to the depth of the counterbore line.

b.

Wedging a block of wood or body wedge between the sway bar and the core support will be helpful to
prevent flex.

c.

Wrapping a piece of rubber hose around the pry bar will be helpful to stop it from slipping.

5.

Once you have achieved the desired depth by pressing the plug past the counterbore line (as shown in step 3), no
further action is required.

6.

Reinstall the Front Cradle Shear Plate. Refer to Front Cradle Shear Plate Replacement (1SV) in SI.

Dealer Responsibility
All new, used, GM Certified Pre-Owned (CPO), courtesy transportation vehicles, dealer shuttle vehicles, CarBravo, etc.
in dealers' possession and subject to this field action must be held and inspected/repaired per the service procedure of
this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to
customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
All GM Certified Pre-Owned (CPO) vehicles currently in the dealers’ inventory within the SHIFT Digital system will be
de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid
warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within
the SHIFT Digital system, or once again be used in the Courtesy Transportation Program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through the end date as noted in the Attention box. Customers who have recently purchased vehicles sold
from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are
to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions
contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers.
Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the
notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service
through the end date as noted in the Attention box, you must take the steps necessary to be sure the program correction
has been made before selling or releasing the vehicle.
Dealer Reports – For USA & Export
For dealers with involved vehicles, a listing has been prepared and will be available through GM Global Connect Maxis
Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that
apply to this field action. This information is intended to assist dealers with the PROMPT COMPLETION of these
vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete
this field action may be a violation of law in several states.
Customer Notification
USA & Canada - General Motors will notify customers of this program on their vehicle (see copy of sample customer letter
included with this bulletin).
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

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 tools, equipment, 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 dealer for information on whether your
vehicle may benefit from the information.
