Important: Implementation of this Service Bulletin by "GM of Canada" dealers requires prior District Service Manager approval.
Some customers may comment that the rear portion of the roof has some rust forming. This condition mainly happens in coastal states.
During production, the E-coating may have missed that portion of the roof.
Replace the rear roof section following the procedure listed below.
• | Luggage rack |
• | Third brake light |
• | Left and right interior quarter panel trim |
• | Headliner |
• | Rear lift gate primary seal |
• | Lift gate or lift glass |
FOR 2 DOOR VEHICLES, measure 65 mm (2 1/2 in) forward of the downturn flange, and mark the cut line the width of the vehicle roof as shown using a tape measure or scale (See Illustration).
Important: While performing this next step, cut through one layer of metal only.
Important: While performing this next step, drill through the roof reinforcement only.
Important:
• Bonding surfaces must be ground clean of material to the bare metal. • Cover and protect the surrounding surfaces from sparks.
• | Dry fit the new part to the body. |
• | While the part is attached to the body, mark the bottom side of the new part in order to determine which area needs to be ground to bare metal. |
• | Remove the part from the body and grind the bottom side of the part to bare metal. |
• | Thinly coat all bare sheet metal on the bottom side of the part with adhesive. |
Important: Pre-fit the service part to ensure proper alignment.
Important: When the service panel has been positioned, do not lift the panel away from the vehicle. If repositioning is necessary, slide the panel only. This maintains proper contact between the two panels.
Important: Prior to refinishing, refer to publication GM4901M-D (GM4901M-D-F for French), GM Approved Refinish Materials Guide for recommended products. Do not combine paint systems. Refer to the paint manufacturer's recommendations.
