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.
•

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.

•

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.
•

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.

•

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

•

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

future, and the vehicle is still covered under the New Vehicle Limited Warranty, you must take the steps necessary to be
sure the service update correction has been made before selling or releasing the vehicle.
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.

de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid

Dealer Reports – For USA & Export
The Inventory tab of the Open Vehicle Report will contain Service Update Bulletin VINs that apply to this field action.
This information is intended to assist dealers with the PROMPT COMPLETION of these vehicles. The Customer InService tab will not contain Service Update Bulletin VIN data because the intent of a Service Update Bulletin is to not
inconvenience a customer with a special trip for service. Service Update Bulletins are to be completed when the
customer is in for a regularly scheduled visit.

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.
