MODELS AFFECTED: 1985 MODELS EQUIPPED WITH CARBURETED ENGINES (VIN CODES X, E, A, AND Y)

The chart on the reverse side updates the System Performance Check Chart on Page 6E1-35 of the 1985 Buick Chassis Service Manual. Please make a note of this change in your copy of the service manual.

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.
