Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003893849
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 AIRBAG” 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 AIRBAG”.
 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000003928809
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000003767031
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
 Only use “DOT 3” or “DOT 4” brake fluid. Refer to MA-11, "
Fluids and Lubricants".
 Never reuse drained brake fluid.
 Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off
immediately and wash with water if it gets on a painted surface.
 Never use mineral oils such as gasoline or light oil. They may damage rubber parts and cause improper
operation.
 Always loosen the brake tube flare nut with a flare nut wrench.
 Tighten the brake tube flare nut to the specified torque with a flare
nut torque wrench (A).
 Always conform the specified tightening torque when installing the
brake pipes.
 Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.
 Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) connector or the battery negative terminal
before performing the work.

ation voltage of the alternator has been adopted. Therefore, the power generation voltage variable
control system operation inspection should be performed after replacing the alternator, and then
make sure that the system operates normally. Refer to CHG-20, "
Inspection Procedure".
Disassembly and AssemblyINFOID:0000000003860540
DISASSEMBLY
Rear bracket assembly
NOTE:
Rear bracket assembly may be hard to remove because a ring is
used to lock outer race of rear bearing. To facilitate removal of rear
bracket assembly, heat only the bearing box section until the temper-
ature increases to approximately 30°C (86°F) with a soldering iron
(200W capacity).
CAUTION:
Never use a heat gun, as if can damage diode assembly.
Front Cover
1. Set rotor to the vise.
CAUTION:
 Be careful not to damage the rotor.
 Use copper plate or thick cloth for rotor in the vise.
2. Remove pulley cap, using suitable tool.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003801896
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. 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 AIRBAG” 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 AIRBAG”.
 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.
Liquid GasketINFOID:0000000003793163
REMOVAL OF LIQUID GASKET SEALING
 After removing mounting nuts and bolts, separate the mating sur-
f a c e u s i n g t h e s e a l c u t t e r [ S S T: K V 1 0 1111 0 0 ( J37228)] (A) and
remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
 Tap (B) the seal cutter [SST: KV10111100 (J37228)] to insert it, and
then slide (C) it by tapping on the side as shown in the figure.
 In areas where seal cutter [SST: KV10111100 (J37228)] is difficult
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 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.

RADIATOR
WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove radiator cap by turning it all the way.
1. Remove the following parts:
 Engine under cover.
 Air duct (inlet): Refer to EM-26, "
Exploded View".
 Horn: Refer to HRN-6, "
Exploded View".
 Hood lock: Refer to DLK-220, "
Exploded View".
2. Drain engine coolant from radiator. Refer to CO-8, "
Draining".
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
3. Disconnect reservoir tank hose from radiator pipe (upper).
4. Disconnect CVT fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of CVT fluid.
5. Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to HA-
38, "Exploded View".
6. Remove radiator cap adapter and radiator hoses (upper) and radiator pipe (upper) assembly.
CAUTION:
Be careful not to allow engine coolant to contact drive belt.
7. Disconnect radiator hose (lower) from radiator.
8. Remove condenser. Refer to HA-46, "
Exploded View".
CAUTION:
Be careful not to damage condenser core.
9. Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).
CAUTION:
Never pull the tabs outside excessively to prevent it from
damping.
10. Lift up and remove radiator from front of radiator core support.
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Note the following, and installation is the reverse order of removal.
Radiator Upper Clip
Install radiator upper clip on radiator core connection as follows:
1. Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.
2. Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.
3. After connecting radiator upper clip, use the following method to
check it is fully connected.
 Visually confirm that two radiator upper clips are connected to
radiator core connections.
 Move radiator upper clip and the radiator forward and backward to check they are securely connected.
