Removal Procedure
Caution: Refer to Approved Equipment for Collision Repair Caution in the Preface section.
Important: Before beginning the repair, refer to
Metal Panel Bonding
for proper adhesive applicator preparations
and general information.
- Disable the SIR system. Refer to
SIR Disabling and Enabling
in SIR.
- Disconnect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Remove all related panels and components.
- Repair as much of the damage as possible to factory specifications. Refer
to
Dimensions - Body
.
- Remove the door assembly. Refer to
Rear Side Door Replacement
in Doors.
- Locate
and drill out all factory welds. Note the number and location of welds at the upper
window frame and the mirror locations.
- Grind
the edges of the door outer panel to separate the outer door panel from the door shell.
Caution: Inspection of the door guard beam for damage must be performed before replacement
of the door outer panel. If damage to the door guard beam is found the door must be
replaced. Failure to do so may compromise the structural integrity of the vehicle
and may cause personal injury if the vehicle is involved in a collision.
- Remove the outer door panel.
- Remove the sealers and anti-corrosion materials from the repair area,
as necessary. Refer to
Anti-Corrosion Treatment and Repair
in Paint and Coatings.
- Straighten
the edges of the door shell.
Installation Procedure
- Using
a grinding disk grind the surface of the door shell, mating the flanges to bare steel.
- Scuff
the opposing mating surfaces of the door outer panel to remove the gloss of the E-Coat.
- Drill
8 mm (5/16 in) plug weld holes, as necessary, in the locations noted
from the original panel.
Important: In any area damaged beyond recognition, space
plug weld holes every 40 mm (1 in) apart.
- Clean the mating surfaces.
Important: The adhesive has a 40-50 minute
working time. Do not allow the door to totally cure off the vehicle, as proper alignment
of the door outer panel to the door shell will be difficult.
- Apply a 3-6 mm (1/8-1/4 in) bead of metal panel bonding
adhesive GM P/N 12378566/7 (Canadian P/N 88901674/5), or equivalent,
to both of the mating surfaces.
- Using a small acid brush, spread a coat of adhesive to cover all the bare
metal surfaces to ensure corrosion protection.
Important: Do NOT pull the panels apart after being
joined together. Slide the panels against each other to realign the panels.
- Install the door outer panel to the door shell.
- Clamp the door outer panel into position, as required.
- Using
a hammer re-hem the hem flanges around the door shell .
Continue to hammer
in stages along the hem flanges.
- Using lacquer thinner remove the excess adhesive from the door panel area.
- Install the door to the vehicle. Inspect the door outer panel for proper
alignment; then adjust the alignment, as required.
- Using
metal-inert gas (MIG), weld the door outer panel to the door frame in the locations
noted at the upper door frame.
- Clean and prepare all welded surfaces.
- Apply
Fusor super flexible anti-flutter foam-fast set, Fusor P/N 121/124, or equivalent,
in 4-5 evenly spaced locations between the door outer panel and the inner safety
beam.
- Apply sealers and anti-corrosion materials to the repair area, as necessary.
Refer to
Anti-Corrosion Treatment and Repair
in Paint and Coatings.
- Paint the repaired area. Refer to
Basecoat/Clearcoat Paint Systems
in Paint and Coatings.
- Install the door assembly. Refer to
Rear Side Door Replacement
in Doors.
- Install all related panels and components.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Enable the SIR system. Refer to
SIR Disabling and Enabling
in SIR.
