Some owners of 1990-92 LeMans models with 1.6L engine may experience a condition of the battery not holding a charge due to a loose alternator belt.
The washer is not hardened and deforms into the adjustment slot of the upper brace, becoming concave and loose, allowing belt to loose tension.
The mounting bolt and washer should be replaced with screw assembly P/N 11508139 prior to retensioning the generator drive belt. Belt tension should be adjusted according to the procedure found in the LeMans Service Manual.
Part is currently available from GMSPO.

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.
