Electrical Ground Repair Overview

M6 Weld Stud Replacement

Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
Proper electrical system function relies on secure,
stable and corrosion-free electrical ground connections.
Loose, stripped, or corroded connections increase the
possibility of improper system function and loss of
module communication. These conditions may also
lead to unnecessary repairs and component
replacement.
In general, electrical ground connections are
accomplished using one, or a combination of the
following attachment methods:
• Welded M6 stud and nut
• Welded M6 nut and bolt
• Welded M8 nut and bolt
Determine which attachment method is used and
perform the appropriate or alternative repair as
described in this bulletin.

Caution: Use only the GM-approved replacement
fasteners with conductive finish for electrical
ground repair.
1. Select a location adjacent the damaged or missing
M6 ground stud having 20 mm (0.79 in) clearance
behind the panel surface and 20 mm (0.79 in)
clearance surrounding the M6 conductive rivet stud
flange.
2. Using GM approved residue-free solvent or
equivalent, remove any grease from the repair site
and allow to dry.
Note: Ensure 20 mm (0.79 in) clearance is
maintained behind the panel to be drilled.

3. Drill a 10 mm (0.40 in) diameter hole through the
panel.

4. Remove paint and primer from the area
surrounding the 10 mm (0.40 in) hole until bare
metal is visible.

Bulletin No.: 10-08-45-001H

2372445

Note: Use the GE-50317 rivet stud tool kit or the
regional equivalent.
6. Place the M6 conductive rivet stud (1) in the 10 mm
(0.40 in) hole. Assemble the rivet stud tool (2) with
the groove and flare side facing the rivet stud, then
the washer and the M6 nut (3).

2382055

Important: The M6 conductive rivet stud as shown,
can accommodate a panel thickness range of
0.7-4.2 mm (0.03-0.17 in). If there are layers of sheet
metal, they should be touching without any air gaps
to ensure a good ground.
5. Select a M6 conductive rivet stud. Refer to the
Parts Information section in this bulletin.

2375142

7. Using a wrench on the rivet stud tool, and a socket
on the M6 nut, secure the M6 conductive rivet stud.
8. Ensure the rivet stud is securely fastened,
WITHOUT ANY detectable movement.
9. Completely wrap the threads of the rivet stud with
painters tape or equivalent.
Note: The rivet stud and surrounding panel area
MUST BE properly refinished PRIOR to the
installation of the ground wire terminal and
conductive nut to maintain a secure, stable and
corrosion-free electrical ground.

10. Refinish the repair area using an anti-corrosion
primer. Refer to Anti-Corrosion Treatment and
Repair in SI.
11. Allow the refinished repair area to cure sufficiently
before removing the protective material applied to
the rivet stud threads.
12. Remove the painters tape or equivalent from the
rivet stud threads.
13. Using GM approved residue-free solvent or
equivalent, thoroughly clean the rivet stud threads
to remove any adhesive and allow to dry.
14. Using a small brush, apply Dielectric Lubricant GM
P/N 12377900 (Canadian P/N 10953529) to the
threads of the M6 conductive rivet stud.
Note: Fretting corrosion is a build-up of insulating,
oxidized wear debris that can form when there is a
small motion between electrical contacts. The
oxidized wear debris can accumulate at the
electrical contact points causing the electrical
resistance across the connection to increase.
15. Carefully remove ANY corrosion or contamination
that may be present on the electrical ground wire
terminal.
16. Install the electrical ground wire terminal to the
rivet stud.
17. Select a M6 conductive nut. Refer to the Parts
Information section in this bulletin.

Tighten
Tighten to 8 Y (71 lb in).
19. Verify proper system operation.

M6 Weld Nut
Caution: Use only the GM-approved replacement
fasteners with conductive finish for electrical
ground repair.
1. If the M6 weld nut at the electrical ground location
is damaged or stripped, a M7 conductive
self-threading bolt may be used to secure the
ground wire terminal.
2. Using GM approved residue-free solvent or
equivalent, remove any grease from the surface
surrounding the weld nut and allow to dry.
3. Remove any loose metal particles from the
damaged or stripped weld nut with a stiff brush.
4. Select a M7 conductive self-threading bolt. Refer to
the Parts Information section in this bulletin.
5. Using a small brush, apply Dielectric Lubricant GM
P/N 12377900 (Canadian P/N 10953529) to the
threads of the M7 conductive self-threading bolt.
Note: Fretting corrosion is a build-up of insulating,
oxidized wear debris that can form when there is a
small motion between electrical contacts. The
oxidized wear debris can accumulate at the
electrical contact points causing the electrical
resistance across the connection to increase.
6. Carefully remove ANY corrosion or contamination
that may be present on the electrical ground wire
terminal.

7. Install the electrical ground wire terminal to the M7
conductive self-threading bolt.
8. Install the M7 conductive self-threading bolt and:

Tighten
Tighten to 9 Y (80 lb in).
9. Verify proper system operation.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
