- Remove the following as necessary:
- Locate, mark and drill out all factory welds holding the roof assembly in place.
- Cut the adhesive bond between the roof and quarter panel with an appropriate tool.
- Remove the roof assembly.
Notice: Some vehicles equipped with sunroofs utilize drain tubes, routed through the upper body pillars, to prevent water from entering the vehicle. Use care not to damage the drain tubes, otherwise, damage to the interior of the vehicle may occur.
Important: The roof is only available as a complete assembly including an outer panel (1) and an inner reinforcement (2). In addition, there are approximately 10 welds in each corner (3) on the inside of the vehicle that must be drilled out to remove the roof assembly.
The headliner, windshield and backglass must be removed prior to removal of the roof assembly. Protect the interior of vehicle. It is advisable to remove the seats due to the required overhead welding.| • | Sealers |
