 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.
