ENGINE COOLANT
If contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir
tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be complete ly empty of coolant and water.
• Apply sealant to the threads of the cylinder bl ock drain plugs. Use Genuine High Performance
Thread Sealant or equivalent. Refer to GI-42, "
Recommended Chemical Product and Sealant".
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is placed at floor level. Make sure the ball valve is in the closed
position.
•Use Genuine NISSAN Long Life Anti-freeze coolant or
equivalent, mixed with distil led water or demineralized
water.
Refer to MA-15, "
Anti-freeze Coolant Mixture Ratio".
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose.
8. Continue to draw the vacuum until the gauge reaches 28 inches of vacuum. The gauge may not reach 28 inches in high altitude
locations, use the vacuum specifications based on the altitude
above sea level.
9. When the vacuum gauge has reached the specifi ed amount, disconnect the air hose and wait 20 seconds
to see if the system loses any vacuum. If the vacuum level drops, perform any necessary repairs to the
system and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for any leaks.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006405461
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:0000000005930800
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• 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 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.

PRECAUTIONS
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 a ll control units using CONSULT-III.
Precaution for Liquid GasketINFOID:0000000005930801
REMOVAL OF LIQUID GASKET SEALING
• After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
• Tap Tool to insert it (1), and then slide it by tapping on the side (2)
as shown.
• In areas where Tool is difficult to use, use plastic hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason suitable tool such as screw-
driver is used, be careful no t to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket applica-
tion surface and the mating surface, using scraper.
• Remove liquid gasket completely from the groove of the liquid
gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-42, "
Recommended Chemical Prod-
uct and Sealant".
4. Apply liquid gasket without breaks to the specif ied location with the specified dimensions.
• If there is a groove for the liquid gasket application, apply liquid gasket to the groove. Tool number : KV10111100 (J-37228)

Do not remove radiator cap when the engine is
hot. Serious burns could occur from high-pressure
engine coolant escaping from radiator. Wrap a thick cl oth 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.
REMOVAL
1. Remove engine under cover. Refer to EI-15, "Removal and Installation".
2. Drain engine coolant from radiator. Refer to CO-36, "
Changing Engine Coolant".

a. Disconnect reservoir tank hose.
b. Release the tab (A) in the direction shown by the arrow ( ).
c. Lift up while removing the reservoir tank hose, and remove it.
5. Disconnect harness connector from fan motor, and move harness aside.
6. Disconnect CVT or A/T fluid cooler hoses if equipped. • Install plug to avoid leakage of CVT or A/T fluid if equipped.
7. Remove radiator hoses (upper and lower).
8. Remove radiator core support cover. Refer to BL-19
.
9. Remove cooling fan assembly.
10. Remove radiator core support (upper) bolts, bolts of stationary part on the radiator core support side and clip. Lift radiator from
radiator (upper) mount part of radiator core support (upper) (2).
