#### DEALER ACTION

Whenever a new vehicle subject to this campaign requires replacement of the partial engine anembly as provided in this bulletin, the following steps must be completed before selling and releasing the vehicle.

1. For new vehicles in dealer inventory, notify prospective purchasers, prior to purchase, that a new partial engine assembly was installed by an authorized dealer at the request of Oldsmobile Division.

2. To avoid unnecessary disputes with the customers and owner dissatisfaction, place the following statement on your sale agreement with the purchaser of a new vehicle on which the services described in this bulletin are performed.

"A new partial engine anembly was installed in this new vehicle by an authorized dealer at the request of Oldsmobile Division."

Dealers are to perform the services described in this bulletin on 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 as instructed before reselling or releasing the vehicle.

#### SERVICE PROCEDURE

#### Inspection

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.
