Removal and Installation

NLFE0018

CAUTION:

Always replace exhaust gaskets with new ones when
reassembling. If gasket remains on flange surface, scrape
off completely as shown at left.

With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.

Check to ensure that mounting brackets and mounting
insulators are installed properly and free from undue
stress. Improper installation could result in excessive
noise or vibration.

Be sure to use genuine exhaust system parts which are
designed

especially

for

heat

resistance,

corrosion

resistance, and shape.

Perform the operation with the exhaust system fully
cooled down because the system will be heated just after
the engine stops.

Be careful not to cut your hand on the insulator edge.

Precautions

NLGI0001

Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.

SGI646

PRECAUTIONS FOR SUPPLEMENTAL RESTRAINT
SYSTEM (SRS) “AIR BAG” AND “SEAT BELT
PRE-TENSIONER”

NLGI0001S01

The Supplemental Restraint System such as “AIR BAG” and “SEAT
BELT PRE-TENSIONER” used along with a seat belt, helps to
reduce the risk or severity of injury to the driver and front passen-
ger for certain types of collision. The SRS system composition
which is available to NISSAN MODEL V10 is as follows (The com-
position varies according to the destination and optional equip-
ment.):

For a frontal collision
The Supplemental Restraint System consists of driver air bag
module (located in the center of the steering wheel), front pas-
senger air bag module (located on the instrument panel on
passenger side), front seat belt pre-tensioners, a diagnoses
sensor unit, warning lamp, wiring harness and spiral cable.

For a side collision
The Supplemental Restraint System consists of front side air
bag module (located in the outer side of front seat), side air bag
(satellite) sensor, diagnoses sensor unit (one of components of
air bags for a frontal collision), wiring harness, warning lamp
(one of components of air bags for a frontal collision).

Information necessary to service the system safely is included in
the RS section of this Service Manual.

WARNING:

To avoid rendering the SRS inoperative, 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 should be performed by an authorized
NISSAN dealer.

Improper maintenance, 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 the RS section.

Do not use electrical test equipment on any circuit related
to the SRS unless instructed to in this Service Manual.
Spiral cable and wiring harnesses covered with yellow
insulation tape either just before the harness connectors
or for the complete harness are related to the SRS.

PRECAUTIONS FOR NATS (NISSAN ANTI-THEFT
SYSTEM)

NLGI0001S02

NATS will immobilize the engine if someone tries to start it without
the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.

PRECAUTIONS

Precautions

GI-3

The security indicator is located on the instrument panel. The indi-
cator blinks when the ignition switch is in “OFF” or “ACC” position.
Therefore, NATS warns outsiders that the vehicle is equipped with
the anti-theft system.

When NATS detects trouble, the security indicator lamp lights
up while ignition switch is in “ON” position.
This lighting up indicates that the anti-theft is not functioning,
so prompt service is required.

When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs),
CONSULT-II hardware and CONSULT-II NATS software is
necessary.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.

Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.

When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A
maximum of five key IDs can be registered into NATS.

When failing to start the engine first time using the key of
NATS, start as follows.

Leave the ignition key in “ON” position for approximately 5
seconds.

Turn ignition key to “OFF” or “LOCK” position and wait approxi-
mately 5 seconds.

Repeat step 1 and 2 again.

Restart the engine while keeping the key separate from any
others on key-chain.

SGI285

GENERAL PRECAUTIONS

NLGI0001S03

Do not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refrig-
erant gas, etc. When working in a pit or other enclosed area,
be sure to properly ventilate the area before working with haz-
ardous materials.
Do not smoke while working on the vehicle.

SGI231

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before work-
ing on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or
transaxle, be careful not to lose your balance and drop them.
Also, do not allow them to strike adjacent parts, especially the
brake tubes and master cylinder.

PRECAUTIONS

Precautions (Cont’d)

GI-4

SEF289H

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

SGI233

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

SGI234

Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.

Replace inner and outer races of tapered roller bearings and
needle bearings as a set.

Arrange the disassembled parts in accordance with their
assembled locations and sequence.

Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents
when required.

Use tools and recommended special tools where specified for
safe and efficient service repairs.

When repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.

Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
