The tool numbers have been revised for the fuel level meter assembly spanner wrenches listed in Section "6C", Page 6C-14, "Engine Fuel", of the 1989-1990 "A" car Service Manuals.
The new tool numbers are J24187/J24187-A or current available tool J36608.
Please make a note in your manuals.
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.
