# SUNROOF-LOOSE CLINCHED NUT REPAIR PROCEDURE

#### VEHICLES AFFECTED: 1986 Cadillac 'C', 'E' and 'K'; 1986 Oldsmobile, Buick 'C' and 'E'

If the clinched nuts used on sunroof module housings loosen and spin during assembly, the following repair procedure should be used.

1. Grasp nut with needle nose pliers to secure until screw is removed.

2. Apply Loctite Super Bonder No. 496 or equivalent between flange of nut and housing. Rotate nuts to spread glue and allow 10 minutes minimum for glue to set-up. If possible, it is preferable to allow eight hours for glue to fully cure.

3. Complete reassembly.

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.
