You should first use GM-approved residue-free solvent to remove any grease from the surface surrounding the weld nut and allow it to dry and remove any loose metal particles from the damaged or stripped weld nut with a stiff brush. Then, you should use a small brush to apply Dielectric Lubricant GM P/N 12377900 (Canadian P/N 10953529) to the new, conductive, self-threading M7 bolt. After that, you should carefully remove any corrosion from the electrical ground terminal and install the electrical ground terminal to the new, conductive M7 bolt and the M7 bolt and tighten to 9 Nm (80 lb in). Finally, you should check for proper system operation.
