Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951676
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.

• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460517
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460518
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

< PRECAUTION >[VQ35DE]
PRECAUTIONS
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage.
Parts Requiring Angular TighteningINFOID:0000000009460520
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.
Precaution for Liquid GasketINFOID:0000000009460521
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
