This bulletin provides an index of all 1990 Chevrolet Dealer Service Bulletins published through October 1991.
The index is supplied in "Section Sequence" to conform to your Service Bulletin Binder.
Vehicles that may be affected by each bulletin are indicated in the vehicle series column for both passenger cars and trucks. Each vehicle series can be identified by referencing a VIN card or examining the vehicle VIN plate, passenger cars "4th position" or trucks "5th position.
Chevrolet Dealer Service Bulletins are provided to inform technicians of conditions that may occur on some vehicles. Each bulletin specifies both the year/model of the vehicles covered and is intended for application on those vehicles only.
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.
