Body Repair: Overview Nissan Note E12

Scheme 99

Description

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-corrosive measures.

Anti-Corrosive Precoated Steel (Galvannealed Steel)

To improve repairability and corrosion resistance, a new type of anticorrosive precoated steel sheet has been 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.

Scheme 100

Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive performance built into the vehicle at the factory.

The following figure shows the areas which are sealed at the factory. Sealant which has been 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 article 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 information.

Technicians are also encouraged to read Body Repair Service Information (Fundamentals) in order to ensure that the original functions and quality of the vehicle can be maintained. The Body Repair Service Information (Fundamentals) contains additional information, including cautions and warning, that are not including in this service information. Technicians should refer to both manuals to ensure proper repairs.

Please note that these information are prepared for worldwide usage, and as such, certain procedures might not apply in some regions or countries.

The symbols used in this section for cutting and welding/brazing operations are shown below.

1. Front pillar butt joint can be determined anywhere within shaded area (A) as shown in the figure. The best location for the butt joint is at position (B) due to the construction of the vehicle. Refer to the «FRONT PILLAR»(ref-675632-S20587234582014120500000) section.
2. Determine cutting position and record distance from the locating indent (A). Use this distance when cutting the service part. Cut outer front pillar over 60 mm above inner front pillar cut position (B).
3. Prepare a cutting jig to make outer pillar easier to cut. Also, this will permit service part to be accurately cut at joint position.
4. An example of cutting operation using a cutting jig is as follows.

Scheme 108

1. Mark cutting lines. Cut position of outer pillar 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 in same manner.
