IN ADDITION, DEALERS ARE TO PERFORM THE CAMPAIGN SERVICES ON ALL AFFECTED VEHICLES AS THEY ARE BROUGHT IN FOR ANY KIND OF SERVICE UNTIL ALL AFFECTED VEHICLES HAVE BEEN CORRECTED.

OWNER NOTIFICATION

OWNERS OF ALL AFFECTED VEHICLES WILL BE NOTIFIED BY CADILLAC OF THIS CAMPAIGN. A COPY OF THE OWNER LETTER IS ATTACHED. A LSIT OF THOSE VEHICLES INVOLVED, WHICH OUR RECORDS INDICATE WERE SOLD BY YOU, IS ENCLOSED FOR YOUR FOLLOW UP. THIS LISTING CONTAINS OWNER NAMES AND ADDRESSES OBTAINED FROM CADILLAC DELIVERY RECORDS AND 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 FOR THE FOLLOW UP NECESSARY TO COMPLETE THIS CAMPAIGN.

1. OPEN THE HOOD AND LOCATE THE PAPER TAG ON THE RIGHT HAND VALVE COVER CONTAINING THE ENGINE SERIAL NUMBER. IF THE ENGINE NUMBER IS BETWEEN D10118410-D10201731, ROTATING THE INJECTION PUMP WILL BE REQUIRED. IN THE EVENT THE ENGINE NUMBER IS NOT WITHIN THESE BREAKPOINTS OR THE ENGINE NUMBER IS MISSING, DO NOT PERFORM THE CORRECTION. PROCEED TO STEP 6.

NOTE: A LIMITED POPULATION OF VEHICLES WITHIN THE AFFECTED ENGINE NUMBER RANGE DETAILED ABOVE MAY HAVE BEEN CORRECTED PRIOR TO DELIVERY TO THE DEALER. THESE VEHICLES CAN BE READILY IDENTIFIED SINCE THEY ALREADY HAVE THE SPECIAL TAPE DESCRIBED BELOW ON THE PUMP FLANGE JOINT. NO FURTHER ACTION IS REQUIRED ON THESE VEHICLES.

2. FOR ENGINES WITHIN THE SERIAL NUMBER BREAKPOINTS, REMOVE THE AIR CLEANER ASSEMBLY.

3. WIPE THE PUMP AND ADAPTER FLANGES CLEAN AND THEN AFFIX THE SPECIAL TAPE PROVIDED. LINE UP THE LONG LINE IN THE CENTER OF THE TAPE WITH JOINT LINE BETWEEN THE ADAPTER AND PUMP FLANGE AS ILLUSTRATED IN FIGURE 1.

4. WITH THE TAPE FIRMLY STUCK IN PLACE, CUT THE TAPE WITH A RAZOR BLADE AT THE JOINT.

5. LOOSEN THE THREE PUMP TO ADAPTER NUTS AND ROTATE THE PUMP TO LINE UP THE MARKS ON THE TAPE AS SHOWN IN FIGURE 2. RETORQUE THE NUTS TO 24 N-M (18 FT.LBS.).

6. REINSTALL AIR CLEANER ASSEMBLY, INSTALL CAMPAIGN IDENTIFICATION LABEL DESCRIBED BELOW AND CLOSE HOOD.

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.
