Installation Procedure
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- Cut the replacement center pillar section in corresponding locations to fit the original panel. The sectioning joint should be trimmed to allow 11/2 times the metal thickness at the sectioning joint.
- Create a 50-mm (2-in) backing plate (A) from the unused portion of the service part. Trim the backing plate as necessary to fit behind the sectioning joint where there is no reinforcement.
- Drill 8-mm (5/16-in) plug weld holes along the sectioning cut on the remaining original part. Locate these holes 13 mm (1/2 in) from the edge and spaced 40 mm (11/2 in) apart.
NOTE: If the location of the original plug weld holes can not be determined, space the plug weld holes every 40 mm (1 1/2 in) apart.
- Drill 8-mm (5/16-in) plug weld holes in the service part as necessary in the locations noted from the original panel and along the sectioning cut.
- Prepare all mating surfaces as necessary.
- Apply GM-approved Weld-Thru Coating or equivalent to all mating surfaces. Refer to ANTI-CORROSION TREATMENT AND REPAIR .
- Fit the backing plate halfway into the sectioning joint, clamp and plug weld to the vehicle.
- Position the center pillar.
- Plug weld accordingly.NOTE: To create a solid weld with minimum heat distortion make 25-mm (1-in) stitch welds along the seam with 25-mm (1-in) gaps between. Then go back and complete the stitch weld.
- Stitch the weld sectioning joint.
- Clean and prepare all welded surfaces.
- Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to ANTI-CORROSION TREATMENT AND REPAIR .
- Paint and repair the area. Refer to BASECOAT/CLEARCOAT PAINT SYSTEMS .
- Install all related panels and components.
- Connect the negative battery cable. Refer to BATTERY NEGATIVE CABLE DISCONNECTION AND CONNECTION .
- Enable the SIR system. Refer to SIR DISABLING AND ENABLING .
