SERVICE GUILD: FUEL TANK OIL CANNING/POPPING

Models Affected: 1988-89 GRAND PRIX

Some 1988-89 Grand Prix vehicles assembled prior to VIN breakpoint 1G2WK14W9KF206642 may exhibit an audible fuel tank oil canning/popping noise. To eliminate this condition, an interim design change that incorporates additional ribbing to the upper and lower fuel tank sections was initiated.

Vehicles exhibiting this condition may be repaired by replacing the existing fuel tank with a new tank, P/N 10140614, following applicable service manual procedures.

Parts are currently available from GMSPO.

Use applicable labor operation and time.

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.
