To: All Chevrolet Dealers

General Motors has determined that certain 1990 C/K 1500-3500 Series light model trucks were produced at the Oshawa Truck Assembly Plant with incorrect certification labels. The month/year was printed as 01/89 instead of 01/90 on these labels although the trucks were assembled correctly.

To correct this condition, a new certification label is to be affixed to each involved vehicle. Since a new label can be easily installed, and to reduce owner inconvenience, new certification labels will be sent directly to owners of record. owners may install the new label or ask a dealer to perform the service at no charge to the owner.

Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records.

Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

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.
