1987 Buick Regal GNX Service Parts List
Attached is the service parts list for the 1987 Buick Regal GNX (G0434 W/GNX-T2L). The applicable service parts for this vehicle are listed in catalog group order in the same fashion as our regular service catalogs. This listing should be used to identify and order the appropriate, exclusive service parts for this limited build vehicle. Service parts which are common with a regular Buick Regal are not shown within this listing. Please refer to your 1982-87 Buick 44W Catalog for these service parts.
NOTICE: GMSPO will screen all dealer orders for exclusive GNX Service Parts shown on this bulletin. The dealer will be required to provide the VIN, engine serial number, and turbocharger serial number of the GNX vehicle being serviced. All three numbers must match a listing maintained at GM Service Parts Operations before a service art order will be processed. Parts identified by an asterisk (*) in this listing will not have their orders "screened" as described above because they are service parts common to other GM vehicles.

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.
