RATTLE FROM FRONT ENGINE MOUNT (REVISED MOUNT)

1988-1989 SKYLARK WITH 2.3L ENGINE (VIN D)

A small number of 1988 and some early built 1989 Skylark models equipped with a 2.3L engine may exhibit a rattle in the front engine mount during engine start up and/or shut off. (Typically most noticeable when the engine is shut off.) A revised mount (under the existing part number 22538994) is currently available from GMSPO to address this condition. The revised mount, although identical in appearance can be identified by a daub of pink paint on the mount top.

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.
