Some 1986-87 Electras and LeSabres may experience a broken air conditioning compressor discharge pipe (broken between the compressor and muffler). If this condition occurs and a new discharge pipe, Part Number 25529255, is ordered from GM PARTS, this number will be superseded by Part Number 25530596. Part Number 25530596 has a larger O.D. tube (3/4") to prevent recurrence.
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.
