INSUFFICIENT LUBRICATION ON DOOR LOCK CYLINDERS

Model and Year: 1989 ALL PASSENGER CARS

TO: ALL CHEVROLET DEALERS:

A number of door lock cylinders may have been assembled with insufficient lubrication. The condition has been corrected at the supplier.

Vehicles may be corrected by using GM lubricant, part number 12345120. If this lubricant is not available, synthetic SAE 5-W-30 engine oil may be substituted.

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.
