Exchange Program for 2007 Model Year 6.2L (RPO L92 Engine)

This bulletin is being revised to cover the Engine Exchange Program for the models listed until December 2008. Please discard Corporate Bulletin Number 07-06-01-008 (Section 06 -- Engine/Propulsion System).

This bulletin will cover the Engine Exchange Program only for the 2007 models listed. This exchange program will be in effect until December 2008. Additional bulletins will be published for each engine or component as they are introduced.

The following engine will be under an exchange program:

-- 2007 Model 6.2L L92 (VIN Code 8)

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 2007 model year engine exchange program will be administered by the GM Product Quality Center (PQC). Dealerships are required to call the PQC, not GM Technical Assistance (TAC), to request an exchange. Prior to calling the PQC, please make sure to complete the "OEM Engine Exchange" template in this bulletin. Use of the templates will minimize the time spent on the telephone and avoid the need of a second call to the PQC.

Guidelines for honoring exchange requests under this 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.

The following list of components are those that are NOT allowed to be serviced during the exchange program. 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.

Important:  Engine repairs or failures that are caused by components external to the engine do NOT fall under the exchange program. For example, engine coolant lines incorrectly installed causing an engine failure will have to go through GMSPO to obtain an engine assembly. The exchange program is created as a way to correct internal concerns and to take 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 GMSPO will be a new production 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. Upon review of the diagnosis, the PQC will establish a case reference number and make arrangements for shipping an exchange unit to your dealership. The replaced engine must be returned to the Warranty Parts Center (WPC). DO NOT SHIP AN ENGINE TO THE (WPC) WITHOUT AN OFFICIAL WPC REQUEST.

Important: Failure to return the replaced engine by the due date will result in the dealership being debited the entire warranty claim (parts and labor). The removed unit must be returned complete in the original exchange shipping container. 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 manifolds, throttle body, etc.). Dealerships returning engines/components that have been even 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 engine. Low oil level could result in internal engine damage.

WPC Request

The Warranty Parts Center (WPC) will fax a Special Part Request to your dealership requesting the return of the removed engine. DO NOT wait for the warranty claim to be paid before returning the removed engine.

The Special Part Request will provide a request number. This request number must be written on the outside of the return container using a permanent marker. Failure to write the request number on the return container may delay the processing of your return.

If you do not receive the WPC Special Part Request, contact Annette Quince at 248-371-9939 (for French call PQC 1-866-654-7654) to obtain the proper paperwork in order to return the removed engine. Failure to return the engine may result in a debit.

1. Remove the engine assembly/component as outlined in the applicable Service Manual.
2. Drain all fluids from the removed engine.
3. Re-torque any fasteners that were loosened or removed to the original torque specification.
4. Remove any plastic shipping plugs and covers from the exchange unit and install them on the removed unit.
5. If the concerned engine leaks, mark the area directly on the engine with a permanent marker.
6. Write the PQC case reference number on the repair order form.
7. Write the PQC case reference number directly on the component in a visible location.
8. Insert a copy of the WPC Special Part Request, repair order with technician comments, and the completed OEM Engine Exchange Worksheet (template in this bulletin) into a plastic bag and securely fasten to the engine.
9. Place the removed engine into the original shipping container.
