# STRIPPED OIL PAN DRAIN PLUG (INSTALL NEW DRAIN PLUG)

#### SUBJECT: STRIPPED OIL PAN DRAIN PLUG (INSTALL NEW DRAIN PLUG)

This bulletin is being revised to correct tap size.

Some 1991 DeVilles, Eldorados, and Sevilles may experience stripping of the engine oil pan drain plug threads during routine service. This condition may be caused by weld spatter on the threads of the oil pan drain hole from the manufacturing operation.

To repair this condition install a new drain plug, P/N 10017615, and retap the oil pan threads with an M12 x 1.75 tap.

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.
