IT HAS BEEN BROUGHT TO OUR ATTENTION THAT THE SHOP MANUALS DO NOT INSTRUCT THE USE OF AN ANTI LOOSENING AGENT WHEN ASSEMBLING LU5 INLET MANIFOLDS. THE BOLTS ATTACHING THE MANIFOLD TO THE BLOCK THAT ARE INSIDE THE PLENUM SHOULD BE COATED WITH LOCKTITE OR ITS EQUIVALENT. THE G.M. LOCKTITE THREAD LOCKING KIT, P/N 1052624, OR BOLT P/N 14067336, WHICH HAS LOCKTITE APPLIED, MAY BE USED.

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.
