PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EBS00U8A
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:
G 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.
G 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.
G 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 Necessary for Steering Wheel Rotation After Battery Disconnect
EBS00U8C
NOTE:
G This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
G Remove and install all control units after disconnecting both battery cables with the ignition knob in the
LOCK position.
G Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ACC position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the LOCK position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Liquid Gasket EBS00U8B
REMOVAL OF LIQUID GASKET SEALING
G After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket seal-
ing.
Revision: June 2006 CO-2 2007 Versa
PRECAUTIONS
Tool number : KV10111100 (J-37228)
A
CAUTION:
Be careful not to damage the mating surfaces.
G Tap Tool to insert it (1), and then slide it by tapping on the side CO
(2) as shown.
G In areas where Tool is difficult to use, use plastic hammer to
lightly tap the parts, to remove it.
C
CAUTION:
If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating sur- WBIA0566E
faces. D
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket applica- E
tion surface and the mating surface, using scraper.
G Remove liquid gasket completely from the groove of the liquid
gasket application surface, bolts, and bolt holes.
F
2. Thoroughly clean the mating surfaces and remove adhering
moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool.

WBIA0567E
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-46, "Recommended Chemical Prod-
ucts and Sealants" . L
4. Apply liquid gasket without breaks to the specified location with the specified dimensions.
G If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
M
G 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.
G Within five minutes of liquid gasket application, install the mat-
ing component.
G If liquid gasket protrudes, wipe it off immediately.
G Do not retighten nuts or bolts after the installation.
G After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION: SEM159F
If there are specific instructions in this manual, observe them.

CHECKING COOLING SYSTEM FOR LEAKS
To check for leaks, apply pressure to the cooling system using Tool.
Tool number : EG17650301 (J-33984-A)
Testing pressure : 157 kPa (1.6 kg/cm2 , 23 psi)
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage. WBIA0568E
Changing Engine Coolant EBS00T7B
WARNING:
G To avoid being scalded, do not change engine coolant when engine is hot.
G Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.
G Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
G Front
When drain all of engine coolant in the system, open water
drain plug on cylinder block. Refer to EM-77, "CYLINDER
BLOCK" .
CAUTION:
G Perform this step when engine is cold.
G Do not spill engine coolant on drive belt.
PBIC3799E
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
Refer to CO-11, "RADIATOR" .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to CO-9, "FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed. Refer to CO-11, "RADIATOR" .
2. Install radiator drain plug.

G If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-77, "CYLIN-
DER BLOCK" . A
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-11, "Components" .
3. Make sure that each hose clamp has been firmly tightened. CO
4. Remove air duct assembly. Refer to EM-16, "AIR CLEANER AND AIR DUCT" .
5. Disconnect heater hose (1) at position ( ) as shown.

6. Fill radiator and reservoir tank to specified level.
G Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2 1/8 US qt, 1-3/4 lmp qt) a minute G
to allow air in system to escape.
G Use NISSAN Genuine Engine Coolant or equivalent
mixed with water (distilled or demineralized). Fill cooling H
system to specification. Refer to MA-11, "RECOM-
MENDED FLUIDS AND LUBRICANTS".
G When engine coolant overflows disconnected heater hose, I
connect heater hose, and continue filling the engine coolant, if
SMA182B
heater hose is disconnected.
7. Install radiator cap. J
8. Install air duct assembly. Refer to EM-16, "AIR CLEANER AND AIR DUCT" .
9. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000
rpm. K
G Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat the engine. L
10. Stop engine and cool down to less than approximately 50◦ Jabse Service Manual Search 2024 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
