NEW OIL DRAIN PLUG GASKET TO REPLACE COPPER GASKET
An improved oil drain plug gasket, Part No. 14090908, is available to replace the copper gasket, Part No. 14079550. The new gasket is a steel washer with captured O-Ring (Viton).
The new O-Ring/Steel gasket is capable of sealing irregular surfaces with light torques while retaining the clamping load over time. Reuse of the O- Ring/Steel gasket does not lessen sealing or torque retention characteristics.
Recommended torque for the O-Ring/Steel gasket is 12-20 lb. ft. (16-27 N.m)
Excessively higher torques may cause deformation, splitting, or loss of sealing capability.
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.
