Some customers driving Buick Regals may comment concerning an engine oil leak. The oil leak may be due to a damaged O-Ring in the engine oil cooler assembly. If the engine oil leak is diagnosed as being due to the oil cooler assembly, a new O-Ring may be obtained by ordering Part Number 10132856. A new engine oil cooler assembly is not required.
Parts are 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.
