CAMPAIGN: VEHICLE EMISSION CONTROL LABEL -INCORRECT
MODELS AFFECTED: 1984 CENTURYS EQUIPPED WITH 3.8L MFI ENGINES (ENGINE VIN CODE 3) CONDITION --------- General Motors has determined that some 1984 Centurys have incorrect information on the vehicle emission control label. These labels state "NO IGNITION TIMING ADJUSTMENT". The label should state "IGNITION TIMING TO BE SET AT 15 DEGREES B.T.D.C." The emission label is required by the Federal Clean Air Act.
DEALER ACTION
Dealers are to install a new correct Vehicle Emission Control Information Label (number 25524875) on vehicles involved, as described in the Label Installation section of this bulletin.
Each dealer will receive a new label for all cars listed on their printout without an owner name and address. Those cars showing a dealer name or no name and address are the dealer's responsibility to correct. Additional labels may be obtained from your zone office. Since the label can easily be installed, it is being mailed directly to owners of records. Owners may install the label personally or request that it be installed by your dealership. Should this occur, the label is to be installed at no charge to the owner. A copy of the owner letter is included with this bulletin.
DEALER MATERIAL
If your dealership has vehicles involved in this campaign, you will receive the following items:
1. Listing of vehicles to campaign that were shipped to your dealership.
2. One label for each vehicle shipped to your dealership for which no owner of record is listed.

Dealer Buick Owner:
General Motors has determined that some 1984 Centurys have incorrect information on the Vehicle Emission Control Label. These labels state "No Ignition Timing Adjustment." The label should state, "Ignition Timing to be set at 15 Degrees B.T.D.C." The emission label is required by the Federal Clean Air Act.
We have enclosed a new correct Vehicle Emission Control Information Label number 25524875 for your vehicle. You may install this label yourself or take it to a Buick Dealer for installation at no charge to you.
To install the Vehicle Emission Control label yourself, instructions are as follows:
1. Open hood of vehicle and locate the old emission label. (Should be located on the left front strut upper mounting housing.) Refer to illustration.
2. Clean the surface of the old label with soapy water and wipe dry.
3. Remove backing from new label and carefully apply label over old label.
NOTICE: DO NOT ATTEMPT TO REMOVE OR LOOSEN THE NEW LABEL ONCE IT HAS BEEN APPLIED AS THIS WILL DEFACE THE LABEL.
If you install the new label, rather than asking your dealer to do it, please tell us by signing and returning the postage-paid pre-addressed reply card. If you have sold, traded, or disposed of your vehicle, please fill out the information requested on the reply card and return it to us. This will assist us in assuring that all affected vehicles have been corrected and will eliminate the necessity for bothering you with follow-up notifications.
Should you choose to have a Buick Dealer install the label, please contact your dealer to arrange a mutually satisfactory service date to have this modification performed. Take the enclosed label with you. Please allow additional time for the dealer to process your vehicle.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
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.
