Whenever the side cover or bottom pan has been removed on any THM 125/125C it is necessary to use LOCTITE 242 (or equivalent) to reduce the potential for leaks on the bolts indicated in the illustration.
Clean the bolts with a suitable solvent to insure that they are free of dirt and oil. Apply Loctite 242 GMSPO P/N 12345382 (or equivalent) to each bolt and allow it to fully cure according to the sealant manufacturer's instructions.
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.
