CORROSION PROTECTION
Description
INFOID:0000000010499717
To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-cor-
rosive measures.
Anti-Corrosive Precoated Steel (Galvannealed Steel)
To improve repairability and corrosion resistance, a new type of anti-
corrosive precoated steel sheet is adopted replacing conventional
zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrodeposition primer.
NISSAN genuine parts are fabricated from galvannealed steel. Therefore, it is recommended that NISSAN
genuine parts or an equivalent be used for panel replacement to maintain the anti-corrosive performance built
into the vehicle at the factory.
Phosphate Coating Treatment and Cationic Electrodeposition Primer
A phosphate coating treatment and a cationic electrodeposition
primer, which provide excellent corrosion protection, are applied to
all body components.
CAUTION:
Confine paint removal during welding operation to an absolute
minimum.
NISSAN genuine parts are also treated in the same manner. Therefore, it is recommended that NISSAN gen-
uine parts or an equivalent be used for panel replacement to maintain anti-corrosive performance built into the
vehicle at the factory.
Anti-corrosive Wax
INFOID:0000000010499718
To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sec-
tions. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

Undercoating
INFOID:0000000010499719
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chip-
ping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoat-
ing which is rust resistant, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in Undercoating
1.
Never apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst that are subjected to heat).
2.
Never undercoat the exhaust pipe or other parts that become hot.
3.
Never undercoat rotating parts.
4.
Apply bitumen wax after applying undercoating.
5.
After putting seal on the vehicle, put undercoating on it.

Stone Guard Coat
INFOID:0000000010499720
To prevent damage caused by stones, the lower outer body panel (fender, door, etc.) have an additional layer
of Stone Guard Coating over the ED primer coating. When replacing or repairing these panels, apply Stone
Guard coating to the same portions as before. Use a coating which is rust preventive, durable, shock-resistant
and has a long shelf life.

Body Sealing
INFOID:0000000010499721
The following figure shows the areas that are sealed at the factory. Sealant that is applied to these areas
should be smooth and free from cuts or gaps. Care should be taken not to apply an excess amount of sealant
and not to allow other unaffected parts to come into contact with the sealant.

• This section is prepared for technicians who have attained a high level of skill and experience in repairing
collision-damaged vehicles and also use modern service tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.
• Technicians are also encouraged to read the Body Repair Manual (Fundamentals) in order to ensure that the
original functions and quality of the vehicle are maintained. The Body Repair Manual (Fundamentals) con-
tains additional information, including cautions and warnings, that are not including in this manual. Techni-
cians should refer to both manuals to ensure proper repair.
• Please note that this information is prepared for worldwide usage, and as such, certain procedures might not
apply in some regions or countries.

• Front pillar butt joint can be determined anywhere within shaded
area as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle.
• Determine cutting position and record distance from the locating
indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm (2.36 in) above the inner front pillar cut
position.
• Prepare a cutting jig to make outer pillar easier to cut. Also, this will
permit the service part to be accurately cut at the joint position.
• An example of cutting operation using a cutting jig is as per the fol-
lowing.
1.
Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar
2.
Align cutting line with notch on jig. Clamp jig to pillar.
3.
Cut outer pillar along groove of jig (at position A).
4.
Remove jig and cut remaining portions.
5.
Cut inner pillar at position B in same manner.
Welding of Ultra High Strength Steel
INFOID:0000000010499783
SPOT WELDING
The spot welding is limited to ultra high strength steel of tensile strength 980 MPa under the conditions listed
below.
CAUTION:
• If this condition is not satisfied, then perform plug welding.
• This condition is inapplicable to ultra high strength steel of tensile strength more than 980 MPa. For
this type of ultrahigh strength steel, perform plug welding.

• Since this condition is applicable only to this vehicle (J11), never apply it to welding conditions of
other vehicles.
Welding condition
PLUG WELDING
To weld ultra high strength steel of tensile strength 980 MPa or more, perform plug welding observing the
welding hole diameter described in the manual.
CAUTION:
• To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder.
• If carbon dioxide gas (CO2 100%) is used for shielding gas of welder, adequate weld strength cannot
be secured. For this reason, always use fuel mixture for shielding gas of welder to prevent.
• When welding hole diameter cannot be satisfied, make multiple holes (smaller diameter) so that the
sum of hole areas becomes equal to the area of the specified weld hole.
