A new improved oil pan drain plug gasket, P/N 14090908, is available to replace the copper gasket. The new gasket is a steel washer with a captured O-ring (Viton) design.

The new O-ring/steel gasket is capable of sealing irregular surfaces with light torques while retaining the clamping load. Reuse of the O-ring/steel gasket does not lessen sealing or torque retention characteristics.

Recommended torque for the O-ring/steel gasket is 16-27 N.m (12-20 lb. ft.).

DO NOT OVER TORQUE THE DRAIN PLUG as the higher torques may cause deformation splitting, or loss of sealing capability to the steel gasket.

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.
