CAMPAIGN:EMISSION TUNE-UP LABEL
SUBJECT: EMISSION TUNE-UP LABEL
MODELS: 1995 GMC TRUCK S/T TRUCKS WITH 4.3L ENGINES (RPO L35) AND MANUAL TRANSMISSION

ADMINISTRATIVE PROCEDURE
Procedures covering this campaign are outlined in Section V of your dealership's "GMC Truck Warranty Claims Processing Manual" #P9119 Rev. 2/94.
Dear GMC Truck Owner:
General Motors has determined that certain 1995 GMC Truck Sonoma Pickups equipped with 4.3L V6 engines and manual transmissions were shipped with an incorrect emission engine family description name on the emission (tune-up) label.
To correct this condition, it is necessary to install a new emission label on the radiator support. Since a new label can easily be installed, and to provide a more convenient method of correction, we are enclosing a label with installation instructions. The new label may be installed by you onto the engine fan shroud of your vehicle (see illustration on back side of this letter). However, if you desire, your GMC Truck dealer will install the label for you at no charge.
Please let us know if you elect to install the label yourself by completing the enclosed postage paid owner reply card and returning it to us. This will assist us in assuring that all affected vehicles have been corrected. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.
Should you choose to have your GMC Truck Dealer install the label for you, please bring the owner reply card, along with the enclosed label, to your servicing GMC Truck Dealer. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. Instructions for performing this service have been sent to your GMC Truck dealer. Please contact your GMC Truck Dealer to arrange a service date as soon as possible. This procedure will take approximately 15 minutes to complete, but you should ask how much additional time your dealer will need to schedule and process your vehicle.
Your GMC Truck dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not service this condition on that date or within five days, we recommend you contact GMC Truck Consumer Relations. Consumer Relations will assist you and your dealer in getting your vehicle corrected. The telephone number of the Consumer Relations office is listed in your Warranty and Owner Assistance Information Manual.
After contacting your GMC Truck dealer and GMC Truck Consumer Relations, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to write the Director, Manufacturers Operations Division (6405J), United States Environmental Protection Agency, 401 M Street, S.W., Washington, D.C. 20460. To ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection test if the recall work is not accomplished.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
