Removal and Replacement

ROOF STRUCTURAL MEMBRANE

REMOVAL

1. Remove headliner.
2. Remove roof support membrane, using a Molding Removal Tool, 3-M p/n 08978.
3. Carefully pull down corner of roof structural membrane enough to insert molding removal tool between roof panel and adhesive. Activate air chisel, while keeping the blade at an angle, ensuring not to flex the roof panel. Evenly separate the adhesive strips from the roof panel until the structural membrane is removed.

NOTE: USE EXTREME CARE WHEN PULLING ON THE STRUCTURAL MEMBRANE, THE ROOF PANEL WILL DENT/DING/CREASE/FLEX AND CAUSE PERMANENT DAMAGE.

4. Using a razor blade scraper tool, scrape off remaining adhesive residue.

INSTALLATION

1. Place headliner in vehicle allowing it to rest in a down position on the seats.

Fig. 20:

2. Outside of the vehicle, using the adhesive supplied, apply five 10 mm (0.39 inch) diameter beads of adhesive within the printed black lines or at the center of membrane strips for the length of the new structural membrane, stopping 38 mm (1.5 inches) before each end (Fig. 20).

NOTE: ADHESIVE MUST BE APPLIED UNIFORMLY IN 10 mm (0.39 INCHES) BEADS. TOO MUCH OR TOO LITTLE ADHESIVE WILL CAUSE ROOF PANEL TO WARP AS ADHESIVE CURES.

3. Apply a 25 mm (1.0 inch) diameter hot glue spot to each location where the glue bond between the headliner and structural membrane had previously been broken free. This bond is not critical to performance but allows the membrane to remain in place while the headliner is installed.
4. Place the structural membrane, adhesive side up, onto the headliner over the glue spots to attach the membrane to the headliner.
5. Install headlining in proper position in vehicle.

NOTE: IT IS NOT NECESSARY TO APPLY LOCAL PRESSURE IN THE AREA OF THE STRUCTURAL MEMBRANE, THE SHAPE AND STIFFNESS OF THE HEADLINER WILL PROVIDE PROPER PRESSURE TO ALLOW THE ADHESIVE TO CURE PROPERLY.
