ENGINE COOLANT
2. Pull the negative-pressure valve to open it and check that it
closes completely when released.
• Check that there is no dirt or damage on the valve seat of the
radiator cap negative-pressure valve.
• Check that there are no abnormalities in the opening and clos- ing conditions of the negative-pressure valve.
3. Check radiator cap relief pressure using suitable tool and Tool. • When connecting the radiator cap to the tester, apply water orcoolant to the cap seal surface.
• Replace the radiator cap if there is an abnormality in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
• Be careful not to bend or damage the radiator fins.
• When radiator is cleaned on-vehicle, remove surr ounding parts in order to access the radiator core.
Tape the harness and electrical connectors to prevent water from entering.
1. Spray water to the back side of the radiator co re using a side to side motion from the top down.
2. Stop spraying when debris no longer flows from radiator core.
3. Blow air into the back side of radiator core using a side to side motion from the top down.
• Use compressed air lower than 490 kPa (5 kg/cm
2, 71 psi) and keep distance more than 30 cm (11.8 in).
4. Continue to blow air until no water sprays out.
5. Check for coolant leaks. Repair as necessary.
Changing Engine CoolantINFOID:0000000009460391
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
DRAINING ENGINE COOLANT
1. Remove the engine under cover. Refer to EXT-17, "Removal and Installation".
2. Open the radiator drain plug at the bottom of the radi ator and remove the radiator filler cap. This is the
only step required when partially draining the cooling system (radiator only).
CAUTION:
• Do not allow the coolant to contact the drive belt.
• Perform this step when engine is cold.
3. Follow this step for heater core removal/replac ement only. Disconnect the upper heater hose at the
engine side and apply moderate air pressure [103.46 kPa (1.055 kg/cm
2, 15 psi) maximum air pressure]
into the hose for 30 seconds to blow t he excess coolant out of the heater core.
4. When draining all of the coolant in the system, re move the reservoir tank and drain the coolant, then clean
the reservoir tank before installation.

REMOVAL
1. Remove radiator cap and drain coolant from radiator. Refer to
CO-12, "Changing Engine Coolant".
CAUTION:
• Perform this step when the engine is cold.
• Do not spill coolant on the drive belt.
2. Remove front air duct. Refer to EM-84, "Removal and Installation"
.
3. Disconnect coolant reservoir hose from the radiator.
4. Remove fender protector side cover (LH/RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded
View".
5. Disconnect radiator hose (upper) and radiat or hose (lower) from the radiator.
CAUTION:
Do not allow the coolant to contact the drive belt.
NOTE:
The radiator hose clamps on the radiator hose (upper ) and on the radiator hose (lower), are not serviced
separately. Radiator hose clamps are part of the radiator hose assembly and serviced as one unit with the
radiator hose.
6. Disconnect the CVT oil cooler hoses.
7. Remove the front bumper fascia. Refer to EXT-17, "Removal and Installation"
.
8. Remove A/C condenser. Refer to HA-30, "COMPRESSOR : Removal and Installation"
.
CAUTION:
Be careful not to damage condenser core.
9. Remove the radiator mounts (upper).
10. Remove radiator. CAUTION:
Do not damage or scratch the radiator core when removing.
INSTALLATION
Installation is in the reverse order of removal.
• After installation, refill coolant and check for leaks. Refer to CO-12, "Changing Engine Coolant"
and CO-11,
"System Inspection".
CAUTION:
Do not spill coolant in engi ne compartment. Use a shop cloth to absorb coolant.
InspectionINFOID:0000000009460394
INSPECTION AFTER INSTALLATION
• Check that the reservoir tank cap is tightened.
• Check for leakage of engine coolant using Tool (B) and suitable tool (A). Refer to CO-11, "System Inspection"
.
WARNING:
Do not remove the radiator cap wh en the engine is hot. Seri-
ous burns could occur from high pressure coolant escaping
from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
• Start and warm up the engine. Visually check that there is no leakage of engine coolant and CVT fluid.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951690
The Supplemental Restraint System such as “A IR 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. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
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 SR 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 three mi nutes before performing any service.
Precaution for Liquid GasketINFOID:0000000009460407
REMOVAL OF LIQUID GASKET
• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use a
plastic hammer to slide (2) the cutter by tapping on the side.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"
.
