CAMPAIGN: STAGED PURGE VALVE. Pontiac LeMans 1981

For 1990-2009 cars

# CAMPAIGN: STAGED PURGE VALVE

#### MODELS AFFECTED 1981 LeMans/Grand LeMans, Grand Prix, Catalina/ Bonneville And Firebird Equipped With 4.3L (RPO LS5, VIN Code S) V8 Engine

#### TO: ALL PONTIAC DEALERS

The Administrator of the Environmental Protection Agency (EPA) has determined that certain 1981 LeMans/Grand LeMans, Grand Prix, Catalina/Bonneville and Firebird model vehicles equipped with 4.3L (RPO LS5, VIN Code S) V8 engines may be emitting pollutants in excess of Federal evaporative emission standards. These standards were established to protect the public health or welfare from the dangers of air pollution. This condition could cause a vehicle to fail an emission inspection test, if required under state or local law.

A staged purge control valve will be installed between the charcoal canister and the carburetor according to the instructions contained in this bulletin.

#### VEHICLES INVOLVED

Involved are certain 1981 LeMans/Grand LeMans, Grand Prix, Catalina/Bonneville and Firebird model vehicles equipped with 4.3L V8 engines and produced within the following VIN breakpoints:

Up To Year Model Beginning And Including ---- ----- --------- ------------- 1981 LeMans/Grand LeMans SOP EOP Grand Prix SOP EOP Bonneville/Catalina SOP EOP Firebird SOP EOP

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 the 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 Pontiac Division (see copy of Owner Letter included with this bulletin).

#### DEALER CAMPAIGN RESPONSIBILITY

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 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.

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. The cost of such restoration will be the responsibility of the vehicle owner.

Dear Pontiac Owner:

This notice is sent to inform you that Pontiac Division is conducting an emission recall that includes your vehicle.

REASON FOR THE RECALL

The Administrator of the Environmental Protection Agency (EPA) has determined that certain 1981 LeMans/Grand LeMans, Grand Prix, Catalina/Bonneville and Firebird model vehicles equipped with 4.3L (RPO LS5, VIN Code S) V8 engines may be emitting pollutants in excess of Federal evaporative emission standards. These standards were established to protect the public health or welfare from the dangers of air pollution. This condition could cause your vehicle to fail an emission inspection test, if required under state or local law. WHAT WE WILL DO

General Motors has agreed to voluntarily recall your vehicle to modify its evaporative emission control system. Specifically, a staged purge control valve will be installed between the charcoal canister and the carburetor.

WHAT YOU SHOULD DO

Please contact your Pontiac dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. It is estimated that parts will be available on or about October 10, 1988. The labor time necessary to perform this service is approximately eighteen (18) minutes. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.

Should your dealer find that your emission system has been intentionally disabled at the time this correction is performed, you will be asked if you wish the system to be restored so that it will function as designed. The cost of such restoration will be your responsibility.

Your Pontiac dealer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however, you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five (5) days, we recommend you contact the Customer Assistance Department, Pontiac Home Office, by calling 1-800-762-2737.

The enclosed owner reply card identifies your Pontiac vehicle. Presentation of this card to ycur dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of the environment and your continued satisfaction with our products.

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.
