CAMPAIGN IDENTIFICATION LABEL
Each vehicle modified in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label."
Each label provides a space to include the five digit dealer code of the dealer performing the campaign service. This information may be inserted with a
typewriter or ballpoint pen.
Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for
periodic servicing by the owner.
Apply "Campaign Identification Label" only on a clean dry surface.
ADMINISTRATIVE PROCEDURE
REFER TO THE CURRENT CHEVROLET SERVICE POLICIES AND PROCEDURES MANUAL AND CLAIMS PROCESSING MANUAL FOR
CAMPAIGN HANDLING AND ADMINISTRATIVE PROCEDURES.
Dear Chevrolet Truck Owner:
General Motors has determined that some 1983-1984 G-Vans, P-Models and 1984 "D" Series (C.U.C.V.) military Light Duty Chevrolet Trucks
equipped with a 6.2L Diesel Engine (RPO LH6 or LL4) may experience a rapid loss of engine oil as a result of crankcase pressure due to condensate
freezing and blocking the crankcase ventilation line.
To prevent the possibility of this condition occurring on your truck during below freezing temperatures, a new design oil filler cap with a pressure relief
valve, should be installed.
A new cap is enclosed for your convenience. Rather than asking you to return to your Chevrolet dealer, it is believed you might wish to install the new
cap yourself. Just remove the old one, dispose of it, and install the new one in its place. If you wish to return your vehicle to your dealer for this change,
they will be pleased to assist, at no charge to you.
If you install the new cap, or if you have sold or traded your vehicle, please let us know by completing the enclosed postage paid owner reply card and
returning it to us. This will assist us in assuring all affected vehicles have been corrected and will eliminate the need to contact you with follow-up
notifications. If you no longer own the vehicle, you may dispose of the new cap.
We are sorry to cause you this inconvenience, however, we have taken this action in the interest of your continued satisfaction with our products. We
appreciate your assistance.
