Owner Letter
Dear GMC Customer:
General Motors has decided that certain 1992 C, K Trucks, and M, L, G Vans equipped with 4.3L engines (RPO LB4 - VIN Code Z or RPO L35 - VIN
Code W) and California emissions equipment (RPO NB2) and GVW less than 8500 lb. may be emitting non-methane hydrocarbons (NMHC) and oxides
of nitrogen (NOx) in excess of California emission standards. This condition may cause a vehicle to fail state mandated emission tests.
To correct this condition, dealers are to replace the catalytic converter catalyst beads.
Instructions for performing this service have been sent to your GMC dealer, and parts are available. Please contact your GMC dealer to arrange a service
date as soon as possible. This procedure will take approximately 45 to 60 minutes to complete, but you should ask how much additional time your dealer
will need to schedule and process your vehicle.
Your GMC dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to
your dealer on the agreed service date and they do not service this condition on that date or within five days, we recommend you contact GMC
Consumer Relations. Consumer Relations will assist you and your dealer in getting your vehicle corrected. The telephone number of the Consumer
Relations office is listed in your Warranty and Owner Assistance Information Manual.
To ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future
recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper
maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection test if the recall work is not accomplished.
Should your dealer find that your emission system has been intentionally disabled, 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.
The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction
to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish us the complete name and address of the person you
sold or traded your vehicle to and return the card to US.
IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires that vehicle emission recall campaigns be completed prior to California registration renewal.
Uncorrected emission recall campaigns will result in the inability to renew your California vehicle registration.
At the time of emission campaign completion, your California dealer will issue a "Campaign Certificate of Completion". Keep this certificate and, if
required, present it to the Department of Motor Vehicles when renewing your California registration as proof of campaign completion.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.
