Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS00289
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 and SB section of this Service Man-
ual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

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
harness connectors.
Precautions for Brake SystemAFS001S3

Recommended fluid is brake fluid “DOT 3”.

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut crowfoot and torque wrench, securely tighten
brake tube flare nuts.

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.

Before working, turn ignition switch OFF and disconnect electri-
cal connectors of ABS actuator and electric unit (control unit) or
battery negative terminal.

When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlAFS001S4

During VDC/TCS/ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This
is normal.

Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating
noise may be heard from engine room. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and
fluid leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

3. Attach liquid gasket tube to the tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
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 the liquid gasket application, apply liq-
uid gasket to the groove.

As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten after mounting bolts and nuts the installation.

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

Install blind plug to avoid leakage of A/T fluid.
6. Removal radiator hoses (upper and lower) and reservoir tank hose. CAUTION:
Be careful not to allow engine coolant to contact drive belts.
7. Remove radiator cooling fan assembly. Refer to CO-21, "
COOLING FAN" .
8. Rotate two radiator upper mount brackets 90 degrees in the direction shown in the figure, and remove them.
9. Lift up and remove radiator. CAUTION:
Do not damage or scratch A/C condenser and radiator core
when removing.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301 (J33984-A)]
and the radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapABS008FW

Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.

b. Screw M8 bolts [pitch: 1.25 mm (0.0492 in) length: approx. 50
mm (1.97 in)] into water pumps upper and lower mounting bolt
holes until they reach timing chain case. Then, alternately
tighten each bolt for a half turn, and pull out water pump.
CAUTION:

Pull straight out while preventing vane from contacting
socket in installation area.

Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump. CAUTION:
Do not disassemble water pump.
INSPECTION AFTER REMOVAL

Check for badly rusted or corroded water pump body assembly.

Check for rough operation due to excessive end play.

If anything is found, replace water pump.

the figure.

Locate O-ring with white paint mark to engine front side.
2. Install water pump. CAUTION:
Do not allow cylinder block to nip O-rings when installing
water pump.

Make sure timing chain and water pump sprocket are
engaged.

Insert water pump by tightening mounting bolts alternately
