Some early built 1987 Allantes may exhibit one of the following conditions:
- The seat belt may not be held firmly against the lower retractor escutcheon when fully retracted, allowing the metal buckle to be trapped between the door and the sill plate when the door is closed.
- Owners may comment on restricted movement caused by insufficient shoulder belt webbing length when the seat is in the full forward position.
Both of these items were corrected simultaneously during mid-model year 1987. An extension was added to the lower retractor assembly to locate the buckle of the belt when it is not in use, and shoulder belt webbing was lengthened to allow additional movement for passengers. Determine which set of belts are in any vehicle by checking whether there is an extension showing through the carpet escutcheon (refer to Figure 1).
To repair these conditions replace the seat belt assembly, the rocker cover escutcheon, and lower retractor cover on both sides of the vehicle with part numbers listed below. Refer to Section 10-9 in the Allante Service Information Manual for the seat belt replacement procedure.
The replacement parts are listed below:
Seat Belt Assembly LH Maroon 12390114 RH Maroon 12390112 LH Saddle Tan 12390113 RH Saddle Tan 12390111
Escutcheon, Rocker Cover Maroon 1645126 Saddle Tan 1645125
Cover, Seat Belt Rocker Retainer LH Black 1645123 RH Black 1645122
For warranty purposes, use Labor Operation C9040 at 1.0 hour for the right belt, C9041 at 1.0 hour for the left belt, or C9047 at 1.4 hours for both belts.
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.
