- If the M8 weld nut electrical ground location is accessible from both sides of the panel, a conductive M8 bolt and a conductive M8 nut may be used to secure the ground terminal. Refer to GM parts catalog for the correct part numbers and application.CAUTION: Use GM approved replacement fasteners with conductive finish for electrical ground repair.
- Select a location adjacent to M8 weld nut having 20 mm (0.79 in) clearance behind the panel surface and 20 mm (0.79 in) clearance surrounding the new electrical ground site.
- Using GM approved residue-free solvent or equivalent, remove any grease from the surface surrounding the ground location and allow to dry.
- Drill a 10 mm (0.40 in) diameter hole through the panel.NOTE: Ensure 20 mm (0.79 in) clearance is maintained behind the panel to be drilled.
- Carefully remove paint and primer from the area surrounding the new ground site until bare metal is visible.
