MODELS/YEARS CERTAIN 1984 CUTLASS SUPREME, CUTLASS CALAIS, DELTA 88, CUSTOM CRUISER, NINETY- EIGHT AND TORONADO MODELS EQUIPPED WITH 5.0L ENGINES (RPO LV2 OR LG8, VIN CODE Y OR 9)
CONDITION
General Motors has determined that certain 1984 Oldsmobile model vehicles equipped with 5.0L engines may experience an inoperative canister purge Thermo Vacuum Switch (TVS). An inoperative canister purge TVS can affect the intended function of the evaporative emission control system.
VEHICLES INVOLVED
Involved are certain 1984 Oldsmobile Cutlass Supreme, Cutlass Calais, Delta 88, Custom Cruiser, Ninety-Eight, and Toronado models equipped with 5.0L engines (RPO LV2 or LG8, VIN Code Y or 9) produced from the start-of-production through the end-of-production.
DEALER ACTION
To prevent the possibility of this condition occurring, dealers are to replace the canister purge TVS on all involved vehicles.
If there is evidence of intentional disablement of the evaporative emission system, the dealer is to notify the vehicle owner of this condition and ask if he/she wants the system restored. Restoration cost is the responsibility of the owner.
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.
Whenever a vehicle subject to this campaign is taken into your used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your used vehicle inventory and arrange for the campaign correction to be performed.
SERVICE PROCEDURE
1. Open hood and install fender covers.
2. Find the Canister TVS (see applicable Figure 1, 2, or 4) and observe the color of its top.

REIMBURSEMENT
Claims for customer reimbursement of reasonable charges for previously paid repairs to replace the Canister TVS, are to be submitted using Labor Operation T4650 and Trouble Code 96. Total reimbursement amount requested should be shown in the sublet column. Do NOT list parts or labor.
Claims must be supported by documentation that reasonably: (1) discloses the associated repair expenses incurred to replace the Canister TVS, (2) identifies the entity or person who performed the repairs, (3) identifies the date of such repairs, and (4) discloses the amount of unreimbursed repair expenses actually paid by the owner. Owners must provide original or certified receipts that are to be retained in the dealer files.
Zone authorization will NOT normally be required; however, if owners requesting reimbursement do not have proper documentation, or the dealer considers the owner's repair expense to be abnormally high, dealers should contact their zone personnel for a review of the owner's request.
When a customer submits a claim for prior replacement of the Canister TVS, dealers are to CONFIRM that TVS P/N 22536551 is in fact on the vehicle by performing the inspection operation called for in Step (2) of the SERVICE PROCEDURE section in this bulletin. If the Canister TVS is found to have a red or white top, the campaign part is to be installed. The appropriate Labor Operation may then be submitted. This last paragraph applies only if the vehicle is still available for inspection.

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.
