1982 and 1983 2000 models without a gage package and equipped with a 1.8L OHC engine (VIN Code O) require a special socket for removal of the oil pressure sending switch. This socket is available from Kent-Moore Tool Division (number J-21757-03), Mac Tools (number SC-46), or Snap-On Tools (number A-1 19A).

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.
