Dear Chevrolet Owner:

General Motors has determined that the crankshaft pulley bolt may fracture on some 1981-1984 Chevrolet Chevette models equipped with a 1.6L gasoline engine, air conditioning, and power steering, causing the accessory drive pulley to separate from the crankshaft. This letter is sent to notify you to take your Chevette to an authorized Chevrolet dealer for preventative service at General Motors' expense and to advise you of the availability of reimbursement by General Motors in the event your car has experienced a pulley bolt fracture.

If this pulley separates from the crankshaft, you may hear an under-hood noise much like a rock contacting the underside of the car. You will continue to have full manual steering control if this condition occurs, but the power assist to the steering will be lost. It is also likely your engine power will be lost as if your car had run out of gas. To prevent a pulley separation from occurring on your vehicle, General Motors is prepared to have authorized Chevrolet dealers take preventative action at no charge to you. We encourage you to have this service performed regardless of whether your vehicle has previously experienced a pulley bolt fracture.

Instructions for this service have been sent to your Chevrolet dealer. Please contact your dealer to arrange a service date. The labor time necessary to make this modification to your vehicle is approximately forty (40) minutes. Please ask your dealer if you wish to know how much additional time will be needed to process your vehicle.

If your Chevette has previously experienced a pulley bolt fracture, and you paid for all or part of the repairs. you should request reimbursement through your Chevrolet dealer. When doing so, you should present tbe dealer with documentation which reasonably confirms the amount of unreimbursed repair expenses due to a pulley bolt fracture, the date of the repair. and the person or entity performing the repair. Documented unreimbursed towing expenses up to $25.00 per occurrence will also be reimbursed. All requests for reimbursement must be presented to the dealer on or before March 1. 1988.

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary repairs in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage-paid owner reply card and returning it to us.

We are sorry for this inconvenience. This action has been taken, however, because of General Motors' desire to assure proper performance of your car and in the interest of customer satisfaction.

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.
