Some 1987-1991 Allantes may experience a condition of wind noise from the base of the soft top sail panel area and/or the soft top rear glass area. This may be caused by a gap between the soft top material and the boot well seal. To repair this condition install an auxiliary seal kit, P/N 3635368, using the following service procedure:
1. Unlatch and raise rear bow to a vertical position.
2. Install the quarter seals using Loctite 401 adhesive or equivalent as shown in Figure 2.
3. Install the back glass lower corner seals using Loctite 401 adhesive as shown in Figure 3.
4. Close and latch rear bow.
Use the most applicable Labour Operation and Time from the Canadian Labour Time Guide.
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.
