Defect Description and Vehicles Involved

To: All Chevrolet/Geo Dealers

General Motors has determined that certain 1992-93 Chevrolet Cavalier, Corsica and Beretta model vehicles equipped with 2.2L Engines (RPO LN2; VIN Code "4") may have been assembled with an intake manifold gasket (between intake manifold and the cylinder head) that will move out of position due to engine thermo cycling. This may result in rough idling, a check engine light coming on, stalling and/or hesitation on acceleration.

To prevent this condition from occurring, dealers are to replace the intake manifold gasket on involved vehicles.





VEHICLES INVOLVED
Involved are certain 1992-93 Chevrolet Cavalier, Corsica and Beretta model vehicles equipped with 2.2L Engines (RPO LN2) and built within the VIN breakpoints shown in the figure.

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. 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. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. 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.

OWNER NOTIFICATION
Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of owner letter included with this bulletin).

DEALER CAMPAIGN RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before owners take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owners letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.
