If a vehicle is brought to the dealership with an A/C related customer comment (such as accessory belt noise or poor A/C performance), check for loose or missing A/C compressor bracket bolts, and correct belt tension.
It is recommended that an adhesive material (such as Loctite 414) be applied to the threads of the new bolts and any loose bolts being reinstalled. Torque all bolts to Shop Manual specifications.
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.
