ENGINE COOLANT
ENGINE COOLANT
InspectionINFOID:0000000005930806
LEVEL CHECK
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” range when engine is cool.
• Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leaks, apply pressure to the cooling system using suit-
able tool and Tool.
WARNING:
Never remove the radiator cap wh en 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.
Changing Engine CoolantINFOID:0000000005930807
WARNING:
• To avoid being scalded, do not change engine coolant when engine is hot.
• 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.
CAUTION:
• Do not spill engine coolant on drive belt.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
• Front
When draining all of engine coolant in the system, open
water drain plug on cylinder block. Refer to EM-203
.
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-40, "
Component".
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system.

8. Remove water pump. CAUTION:
• Handle water pump vane so that it does not contact any other parts.
• Water pump cannot be disassembled and should be replaced as a unit.
INSPECTION AFTER REMOVAL
• Visually check that there is no significant dirt or rusting on water
pump body and vane (A).
• Make sure that there is no looseness in vane shaft, and that it turns smoothly when rotated by hand.
• Replace water pump, if necessary.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006414971
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 severi ty 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 w hether 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 inoper ative, 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 in correct removal and installation of the SRS can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000005928721
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NVIS /IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
• Always use CONSULT-III 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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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.)
