Condition, Vehicles & Dealer Information

CONDITION

General Motors has determined that some 1981 and 1982 Oldsmobile Toronado, Ninety-Eight, Delta 88, Custom Cruiser and Cutlass Supreme models equipped with a 4.3L or 5.0L V-8 gasoline engine may develop a restricted exhaust due to the catalytic converter becoming plugged.

VEHICLES INVOLVED

Involved are ALL 1981 and 1982 Toronado, Ninety-Eight, Delta 88, Custom Cruiser, and Cutlass Supreme models equipped with a 4.3L or 5.0L V-8 gasoline engine (VIN Codes F, 8 and Y).

Vehicles that have had the catalytic converter replaced since approximately June 1, 1983 with the new type basketed converter assembly or that have had the converter kit part number listed in this bulletin and in Dealer Technical Bulletin 82-T-27 installed, need not have this campaign performed.

DEALER ACTION

To correct this condition on vehicles involved the catalytic converter will require replacement.

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

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.

Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required modification according to instructions contained in this bulletin.
