CAMPAIGN: SHOULDER BELT BRKT. INSTALL NEW ROTATION BRKT.
Models: 1990 Chevrolet Lumina Sedans 1990 Pontiac Grand Prix Sedans 1990 Oldsmobile Cutlass Supreme Sedans 1991 Buick Regal Sedans
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in certain 1990 Lumina, Grand Prix, Cutlass Supreme and 1991 Regal model vehicles. The front seat shoulder belt webbing in these vehicles may separate at the front seat shoulder belt upper guide loops (driver and/or passenger side). Separation of the webbing would occur without prior warning and could increase the risk of injury to belted front outboard occupants in a high energy vehicle crash. During a high energy crash event, this condition may occur if the front seat shoulder belt upper guide loop "dumps" the seat belt webbing into one corner of the guide loop and cuts the webbing.
To prevent this condition from occurring, dealers will install a controlled rotation bracket on both the driver and passenger side front seat shoulder belt guide loops. This bracket will limit the front seat shoulder belt upper guide loop's range of travel, preventing the webbing from being cut.
VEHICLES INVOLVED:
Involved are certain 1990 Chevrolet Lumina Sedan, Pontiac Grand Prix Sedan, Oldsmobile Cutlass Supreme Sedan and 1991 Buick Regal Sedan model vehicles built within the following VIN breakpoints:

SERVICE PROCEDURE:
Tools Required: J-39049 Shoulder Belt Guide Loop Holder
NOTICE: Figure 1 below illustrates all required parts/changes to complete the campaign procedure. Figures 2-4 of this procedure are found on pages 5-7. All parts required for this procedure are included in the service kit.
1. Lower front door window glass and remove (pry off) plastic shoulder belt plug cover working from the outside of vehicle (Fig. 2, View "A").
2. Remove nut and rubber washer from guide loop stud using tool J-39049 (Fig. 2, View "B") to prevent guide loop from turning while removing nut. Retain rubber washer for reinstallation.
NOTICE: Certain early production vehicles may utilize a shoulder on the trim cover in place of rubber washer. This condition is normal. For vehicles with this style trim cover, disregard references to rubber washer and proceed with remainder of repair.
3. Select bracket designated by the word "LEFT" for the driver's side front door and the bracket designated by the word "RIGHT" for the passenger's side front door (Fig. 2, View "C").
4. Working on the outside of vehicle, install appropriate bracket for the door being repaired onto back side of shoulder belt guide loop. Insert locators on bracket into the depressions in the back of the shoulder belt guide loop (Fig. 2, View "D").
NOTICE: If the depressions in the back of the shoulder belt guide loop have plastic "flashings" in the holes from the moulding process, it will be necessary to remove these "flashings" with a drill bit (5 mm) or a knife. This allows the bracket to sit flat against the shoulder belt guide loop. If a drill bit is used for this procedure, turn the drill bit by hand. Do not drill through front of guide loop (Fig. 3, View "A").
5. Insert new, larger diameter nut (with plastic silencer) through anchor plate and place rubber washer over shoulder of nut (between anchor plate and guide loop with bracket installed).
6. Put guide loop with bracket into place and thread new nut onto the guide loop stud (Fig. 3, View "B"). Torque nut to 28 N.m (21 lb. ft).
NOTICE: To prevent guide loop from turning while installing nut, use tool J-39049. DO NOT USE BRACKET STOP TABS TO HOLD SHOULDER BELT GUIDE LOOP WHILE TIGHTENING NUT AS THIS MAY DAMAGE THE BRACKET.
7. Rotate safety belt guide loop and verify that it rotates freely between the bracket stop tabs.
8. Using a sharp knife or razor blade, remove retaining tabs from plastic anchor nut cover. Be sure to remove entire tab so that a flat surface remains as shown in Figure 3, View "C."
9. Lightly sand face of shoulder belt cover plug so that surface is flat and fire of burrs.
10. Lightly sand face of trim cover as shown in Figure 3, View "D." Take care to sand only where the shoulder belt
11. Apply adhesive to plastic shoulder belt cover plug by placing the brown backing paper with adhesive onto the shoulder belt cover plug and press firmly. Carefully remove brown backing paper. Be sure adhesive remains on the shoulder belt cover plug.

Dear General Motors Customer:
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in certain 1990 Chevrolet Lumina Sedan, Pontiac Grand Prix Sedan, Oldsmobile Cutlass Supreme Sedan and 1991 Buick Regal Sedan model vehicles. The front seat shoulder belt webbing in these vehicles may separate at the front seat shoulder belt upper guide loops (driver and/or passenger side). Separation of the webbing would occur without prior warning and could increase the risk of injury to belted front outboard occupants in a high energy vehicle crash. During a high energy crash event, this condition may occur if the front seat shoulder belt upper guide loop "dumps" the seat belt webbing into one comer of the guide loop and cuts the webbing.
To prevent this condition from occurring, your General Motors dealer will install a controlled rotation bracket on both the driver and passenger side front seat shoulder belt guide loops. This bracket will limit the front seat shoulder belt upper guide loop's range of travel, preventing the webbing from being cut.
This service will be performed for you at no charge.

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.
