This bulletin contains information as a supplement to the 1985 and 1986 Cadillac DeVille and Fleetwood Service Information Manuals.

This information is not applicable to Cadillac based limousines manufactured and marketed by any source other than Cadillac Motor Car Division, General Motors Corporation.
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.
