PRECAUTIONS

types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this

Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, it is recommended that all maintenance

and repair be performed by an authorized NISSAN/INFINITI dealer.

• Improper repair, including incorrect removal and installation of the SRS, can lead to personal injury

caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module,

see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness

connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with

a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery or batteries, and wait at least 3 minutes before performing any service.

Special Cautions to Ensure the Safe Disposal of Sodium-filled Exhaust Valves

INFOID:0000000012197230

Handling and disposal of sodium-filled exhaust valves requires spe-

cial care and consideration. Under conditions such as breakage with

subsequent contact with water, metal sodium which lines the inner

portion of exhaust valve will react violently, forming sodium hydrox-

ide and hydrogen which may result in an explosion. Sodium-filled

exhaust valve is identified on the top of its stem as shown in illustra-

tion.

DEALER DISPOSAL INSTRUCTIONS

CAUTION:

• Use approved shatter-resistant eye protection when performing this procedure.

• Perform this and all subsequent disposal work procedures in an open room, away from flammable

liquids. Keep a fire extinguisher, rated at least 10 ABC, in close proximity to the work area.

• Be sure to wear rubber gloves when performing the following operations.

• Make sure the resultant (high alkalinity) waste water does not contact your skin. If the waste water

does contact you, wash the contacted area immediately with large quantities of water.

• Dealers should check their respective state and local regulations concerning any chemical treatment

or waste water discharge permits which may be required to dispose of the resultant (high alkalinity)

waste water.

< PRECAUTION >

[MR FOR NISMO RS MODELS]

1. Clamp valve stem in a vice.
2. The valve has a specially-hardened surface. To cut through it,

first remove a half-round section, approximately 30 mm (1.18 in)

long using air-powered grinder until black color is removed and

silver color appears.

3. Use hacksaw to cut through approximately half the diameter of

valve stem. Make the serration at a point 40 mm (1.57 in) from

the end of valve stem.

4. Cover the serrated end of the valve with a large shop towel (A).

Strike the valve face end with a hammer, separating it into two

pieces.

5. Fill a bucket (such as a 20 oil can) with at least 10 (2-5/8

US gal, 2-1/4 lmp gal) of water. Carefully place the alreadycut

(serrated) valves into the water one-at-a-time using a set of

large tweezers and quickly move away at least 2.7 m (9 ft).

6. The valves should be placed in a standing position as shown in

the illustration to allow complete reaction. After the bubbling

action has subsided, additional valves can be placed into the

bucket allowing each subsequent chemical reaction to subside.

However, no more than 8 valves should be placed in the same
10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The com-

plete chemical reaction may take as long as 4 to 5 hours.

Remove the valves using a set of large tweezers after the chem-

ical reaction has stopped. Afterwards, valves can be disposed

as ordinary scrap.

PRECAUTIONS

INSPECTION, REPAIR AND REPLACEMENT

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and

replace if necessary.

REMOVAL AND DISASSEMBLY

• When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-

structed operations.

• Exercise maximum care to avoid damage to mating or sliding surfaces.

• 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.

• Must cover openings of engine system with a tape or equivalent, to seal out foreign materials.

• Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.

• 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 specified, do exactly as specified. Power tools may be used

in the step.

ASSEMBLY AND INSTALLATION

• Use torque wrench to tighten bolts or nuts to specification.

• 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 engine oil or engine 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.

• After disassembling, or exposing any internal engine parts, change engine oil and replace oil filter with a new

one.

• Release air within route when refilling after draining engine coolant.

• After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and

exhaust gases for leakage.

Precaution for Handling High Pressure Fuel System

INFOID:0000000012197232

• High pressure fuel system components are between high pressure fuel pump and fuel injector.

• Always release fuel pressure and never start the engine when performing removal and installation.

• When removing or installing parts without releasing fuel pressure, fuel may be splashed and, if fuel contacts

skin or eyes, it may cause inflammation.

Parts Requiring Angle Tightening

INFOID:0000000012197233

• Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:

- Camshaft sprocket (INT) bolt

- Cylinder head bolts

- Main bearing cap bolts

- Connecting rod cap bolts

- Crankshaft pulley bolt (No the 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.

LIQUID GASKET APPLICATION PROCEDURE

1. Using a scraper (A), remove old liquid gasket adhering to the liq-

uid gasket application surface and the mating surface.

• Remove liquid gasket completely from the groove of the liquid

gasket application surface, mounting bolts, and bolt holes.

2. Wipe the liquid gasket application surface and the mating sur-

face with white gasoline (lighting and heating use) to remove

adhering moisture, grease and foreign materials.

3. Attach liquid gasket tube to the tube presser (commercial ser-

vice tool).

Use Genuine RTV Silicon Sealant or equivalent. Refer to

GI-

4. Apply liquid gasket without gaps to the specified location accord-

ing to the specified dimensions.

• If there is a groove for liquid gasket application, apply liquid

gasket to the groove.

• As for bolt holes (B), normally apply liquid gasket inside the

holes. Occasionally, it should be applied outside the holes.

Check to read the text of this manual.

• Within five minutes of liquid gasket application, install the mat-

ing component.

• If liquid gasket protrudes, wipe it off immediately.
