DATE: Dec.. 9, 1983
MODELS/YEARS 1984 CUTLASS SUPREMES AND CUTLASS SECTION: 6F
CALAIS' EQUIPPED WITH 5.0L (LV2) V-8 GASOLINE ENGINE
CONDITION
General Motors has determined that some 1984 Oldsmobile Cutlass Supreme and Cutlass Calais models, equipped with a 5.0L (LV2) V-8 gasoline engine, may have been assembled with the upper cover omitted from the catalytic converter. This cover provides additional insulation between the top of the converter and the underbody.
VEHICLES INVOLVED
Involved are certain early production 1984 Oldsmobile Cutlass Supreme and Cutlass Calais models equipped with 5.0L (LV2) V-8 gasoline engines between the following serial numbers.
Assembly Plant Serial Numbers
Lansing EM300100 to EM305270
Arlington ER300004 to ER300557
Not all vehicles within the serial number ranges listed and equipped with a 5.0L (LV2) V-8 gasoline engine were produced without insulation and an upper cover on the catalytic converter. Oldsmobile records indicate 257 vehicles must be inspected to locate approximately 170 misbuilt catalytic converters.
DEALER ACTION
To correct this condition on vehicles involved the catalytic converter will require inspection for the presence of an upper cover. If no upper cover is present the catalytic converter is to be replaced.
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.
