PRE-TENSIONER"
INFOID:0000000012431679
The Supplemental Restraint System such as “AIR 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 the 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.

PRECAUTIONS
• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
check that dowel pins are installed in the original position.
• Cover openings of engine system with a tape or equival ent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and reassembly.
• When loosening nuts and bolts, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specified, do exactl y as specified. Power tools may be used in the step.
Inspection, Repair and ReplacementINFOID:0000000012431684
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Assembly and InstallationINFOID:0000000012431685
• Use torque wrench to tighten bolts or nuts to specification.
• Tighten nuts and bolts in order exactly as specified in the procedure. If a tightening order or procedure is not
specified, tighten nuts and bolts equally in several differ ent steps. Start with the nuts or bolts in the center
and then tighten diagonally starting with the inside and moving to the outside in a spiral pattern.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for restrictions and blockages.
• Avoid damaging sliding or mating surfaces. Before assembling, completely remove foreign materials such as cloth lint or dust, and oil the sliding surfaces.
• After refilling engine coolant, bleed the air from the cooling system.
• After repairing, start the engine and increase engine s peed to check for engine coolant leaks, fuel leaks,
engine oil leaks, and exhaust gas leaks.
Parts Requiring Angle TighteningINFOID:0000000012431686
• For the final tightening of the following engine parts use Tool:
- Camshaft sprocket (INT) bolt
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (Note an angle wrench is required as bolt flange is provided with notches for angle 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:0000000012431687
REMOVAL OF LIQUID GASKET SEALING
• 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. Tool number : KV10112100 (BT-8653-A)
