GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer".

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.
