2.2L ENGINE EXCHANGE PROGRAM

VEHICLES AFFECTED: 1990 CHEVROLET BERETTA, CORSICA, CAVALIER

For 1990 a new increased displacement 2.2L engine has been introduced. To gain needed product feedback, an engine exchange program will be in effect until December 31, 1989. Engine concerns that should trigger a need for an engine exchange include:

Internal engine noise

High oil consumption

Head gasket leakage

Low compression

IMPORTANT: For the items listed above, DO NOT DISASSEMBLE OR REPAIR any 2.2L engine which will require removal of the cylinder head, oil pan or front timing chain cover.

EXCHANGE PROCEDURE:

The exchange program will be administered through the Technical Assistance Centre (T.A.C.).

T.A.C. will arrange with the Tonawanda Engine Plant to directly ship a replacement engine within 24 hours. The replacement engine will be complete except for accessories.

T.A.C. will provide a T.A.C. case number for each engine exchange. This number must be recorded on the identification card supplied with the replacement engine and affixed to the problem engine to be returned. The identification card must be filled out completely.

The exchange unit must be returned to Tonawanda within 10 days in the original shipping crate to avoid a chargeback.

The exchange engine must be complete as removed from the vehicle. Dealerships returning incomplete units will be subject to being billed for materials missing.

Shipping instructions will be included with the new engine.

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.
