• After removing mounting nuts and bolts, separate the mating sur-

face using the seal cutter [SST: KV10111100 (J-37228)] (A) and
remove old liquid gasket sealing.

CAUTION:

Be careful not to damage the mating surfaces.

• Tap (B) the seal cutter [SST: KV10111100 (J-37228)] to insert it,

and then slide (C) it by tapping on the side as shown in the figure.

• In areas where the seal cutter [SST: KV10111100 (J-37228)] is dif-

ficult to use, use a plastic hammer to lightly tap the parts, to
remove it.

CAUTION:

If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1.

Using a scraper (A), remove old liquid gasket adhering to the
gasket application surface and the mating surface.
• Remove liquid gasket completely from the groove of the gas-

ket 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 Silicone Sealant or equivalent. Refer to

GI-18, "Recommended Chemical Products and Sealants"

.

4.

Apply liquid gasket without breaks to the specified location with
the specified dimensions.
• If there is a groove for liquid gasket application, apply liquid

gasket to the groove.

• As for bolt holes, normally apply liquid gasket inside the holes.

Occasionally, it should be applied outside the holes. Check to
read the text of this manual.

• Within 5 minutes of liquid gasket application, install the mating

component.

• If liquid gasket protrudes, wipe it off immediately.
• Never retighten mounting bolts or nuts after the installation.
• After 30 minutes or more have passed from the installation, fill

engine oil and engine coolant.

them.

FOR MEXICO

FOR MEXICO : Precaution for Procedure without Cowl Top Cover

INFOID:0000000005681907

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

FOR MEXICO : Precaution for Supplemental Restraint System (SRS) "AIR BAG" and 
"SEAT BELT PRE-TENSIONER"

INFOID:0000000005681909

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 severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” 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 must be performed by
an authorized NISSAN/INFINITI 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 “SRS AIR BAG”.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

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

WARNING:

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

ignition ON or engine running, DO NOT 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, and wait at least 3 minutes before performing any service.

FOR MEXICO : Precaution Necessary for Steering Wheel Rotation after Battery Dis-
connect

< PRECAUTION >

PRECAUTIONS

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)

3.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

4.

Perform the necessary repair operation.

5.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

6.

Perform self-diagnosis check of all control units using CONSULT-III.

FOR MEXICO : Precaution for Drain Engine Coolant and Engine Oil

INFOID:0000000005681913

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.

• Cover openings of engine system with a tape or the equivalent, if necessary, 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.

FOR MEXICO : Precaution for Inspection, Repair and Replacement

INFOID:0000000005681916

replace if necessary.

FOR MEXICO : Precaution for Assembly and Installation

INFOID:0000000005681917

• 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.
• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
