General Motors has determined some 1987 Pontiac 6000 models equipped with a 2.5L engine may experience loss of serpentine accessory drive belt tension. This condition results in loss of accessory drive component operation.
To prevent the possibility of this condition occuring, the serpentine belt tensioner must be inspected for suspect codes and, if required, replaced.
Involved are certain 1987 Pontiac 6000 models equipped with a 2.5L engine (RPO LR8, VIN Code R) and produced within the following VIN breakpoints:
PLANT BEGINNING THROUGH ----- --------- -------
Oshawa H9271364 H9277849 Tarrytown HT271248 HT274839
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 the involved dealers with the campaign bulletin. Owner name and address data 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 such 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).
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required correction according to instructions contained in this bulletin.
Parts required to complete this campaign are to be obtained from General Motors Service Parts Operation (GMSPO). To insure that these parts are obtained as soon as possible they should be ordered on a C.I.O. order with no special instruction code, but on advise code (2).

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.
