GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these 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
my intake manifold gasket went bad on my 99 monte carlo. 4 tries later the mechanic still could not get it to stop leaking. found out tons of these have crappy intake manifold gaskets. sorry to hear it. my advice, pay the $850 and have the dealer do it instead of the $650 that firestone charged and needed 4 times to fix it.
