IMPORTANT: Due to the limited usage of Part Number 25056682 (lower bed bead kit), dealers are requested to order the actual number of parts required for the repair.

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 was not shipped any involved vehicles.

OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division as parts become available. 1981 vehicles will be campaigned first. (See copy of Owner Letter included with this bulletin.)

Owners who have previously had their catalytic converter replaced with a single bed bead converter or new dual bed bead converter identified by P/N listed in Column 2, Page 3 of this bulletin because of a malfunction should not receive notification or appear on the dealers computer listing.


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.

CAUTION: The catalytic converter beads contain platinum, palladium and/or rhodium. Additionally, the beads may be finely coated with lead compounds. Therefore, precautions should be taken to minimize dust generation during the replacement procedure. These precautions include:

A. Catalyst dust should be controlled by wetting with water prior to bead removal as described in Step 5.

B. The use of a suitable dust mask, rubber gloves and safety glasses is recommended when handling catalyst beads.

C. Applicable OSHA standards should be reviewed.

D. Allow converter to cool before handling.
