CAMPAIGN: WATER PUMP PULLEY (INSPECT DATE CODE)

MODELS AFFECTED 1988 Pontiac 6000 Equipped With 2.5L Engine (RPO LR8, VIN Code R)

General Motors has determined that certain 1988 Pontiac 6000 model vehicles equipped with a 2.5L engine may have been produced with a water pump pulley that could fracture. This could result in loss of accessory drive components including power steering assist, generator and water pump. The engine will continue to run, but the driver would be warned of the failure by one or more of the following conditions:

A. Signal by generator light or gage of loss of voltage.

B. Likelihood of noise at time of failure.

C. Signal by temperature light or gage if engine overheats.

D. Loss of power steering assist.

To prevent this condition from occurring, dealers are to inspect the water pump pulley date code on all involved vehicles, and replace pulleys as required.

VEHICLES INVOLVED

Involved are certain 1988 Pontiac 6000 model vehicles equipped with a 2.5L engine and produced within the following VIN breakpoints:

Beginning Up To And Including --------- ------------------- Oshawa J9201282 J9232022 Tarrytown JT202479 JT218385

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from 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 to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

Owners will be notified of this campaign on their vehicles by Pontiac Division (see copy of Owner Letter included with this bulletin).

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.
