The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle

3. Remove the vent screens (1), located in the base of the distributor, by inserting a plastic-handled, long blade awl
or pick (2) into each of the two airflow vent holes and popping out the screen. If there are no EIP vent screens in
the airflow vent holes, check the vent holes for debris and clear as necessary before reassembling the
distributor.
4. If the EIP vent screens are not present, the distributor cap and rotor do not require replacement.
5. Install the foam sleeve, P/N 15190971, around the section of the A/C accumulator line that is routed directly
above the distributor. Cut a slit in the sleeve and secure it to the line using tie-straps. Do not install a new foam
sleeve if a sleeve is already in place on the A/C accumulator line.

bulletin).
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the
customer notification letter recommends that customers have their vehicles serviced as soon as possible. It also
advises that failure to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a
state or local emission inspection test if the recall work is not completed.

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample
letter.

Dealer Recall Responsibility – ALL
All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the
service procedure of this recall bulletin before customers take possession of these vehicles.
Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of
vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no
customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made
to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter
is provided in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this
purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for
service in the future, you must take the steps necessary to be sure the recall correction has been made before
selling or releasing the vehicle.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA OR EXPORT***
When a California emissions recall is completed by a GM dealer, the dealer must provide the vehicle owner a “Proof
Of Correction Certificate” which the owner may need to present to the California Department Of Motor Vehicles
(DMV) when renewing their vehicle registration. Without this correction certificate, the owner may be unable to
renew their vehicle registration.
Additional Certificates can be obtained, at no charge, from Dealer Support Materials by calling 1-866-700-0001

vehicle.
Reason For This Recall
Your 2001-03 Chevrolet Silverado or GMC Sierra model vehicle, equipped with a 4.3L V6 engine, has an ignition

What Will Be Done
Your dealer will inspect the ignition distributor ventilation holes and, if necessary, replace the distributor cap and
rotor, remove the distributor vent screens and install a foam sleeve around the A/C accumulator line. This service will
be performed for you at no charge.
How Long Will the Repair Take?
This service correction will take approximately 40 minutes. However, due to service scheduling requirements, your
dealer may need your vehicle for a longer period of time.
Contacting Your Dealer
Please contact your GM dealer as soon as possible to arrange a service date and to assure parts availability.
Instructions for making this correction have been sent to your dealer. Please ask your dealer if you wish to know how
much time will be needed to schedule, process and repair your vehicle.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance
Center at the number listed below. The Customer Assistance Center’s hours of operation are from 8:00 AM to 11:00

Emission Law Information
In order to ensure your full protection under the emission warranty made applicable to your vehicle by State or

Also, your vehicle may fail a state or local emission inspection if this recall is not accomplished.
IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to
California registration renewal. Uncorrected emission recalls will result in the inability to renew your
California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof Of Correction
Certificate". Keep this certificate and, if required, present it to the Department of Motor Vehicles when
renewing your California registration as proof of recall completion.
