RADIATOR
WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth 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.
1. Remove the following parts:
 Engine under cover.
 Air duct (inlet): Refer to EM-26, "
Exploded View".
 Horn: Refer to HRN-6, "
Exploded View".
 Hood lock: Refer to DLK-220, "
Exploded View".
2. Drain engine coolant from radiator. Refer to CO-8, "
Draining".
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
3. Disconnect reservoir tank hose from radiator pipe (upper).
4. Disconnect CVT fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of CVT fluid.
5. Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to HA-
38, "Exploded View".
6. Remove radiator cap adapter and radiator hoses (upper) and radiator pipe (upper) assembly.
CAUTION:
Be careful not to allow engine coolant to contact drive belt.
7. Disconnect radiator hose (lower) from radiator.
8. Remove condenser. Refer to HA-46, "
Exploded View".
CAUTION:
Be careful not to damage condenser core.
9. Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).
CAUTION:
Never pull the tabs outside excessively to prevent it from
damping.
10. Lift up and remove radiator from front of radiator core support.
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Note the following, and installation is the reverse order of removal.
Radiator Upper Clip
Install radiator upper clip on radiator core connection as follows:
1. Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.
2. Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.
3. After connecting radiator upper clip, use the following method to
check it is fully connected.
 Visually confirm that two radiator upper clips are connected to
radiator core connections.
 Move radiator upper clip and the radiator forward and backward to check they are securely connected.

P0420, P0430 THREE WAY CATALYST FUNCTION
P0420, P0430 THREE WAY CATALYST FUNCTION
DTC LogicINFOID:0000000003856631
DTC DETECTION LOGIC
The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of A/F sensor 1 and heated oxygen sensor
2 approaches a specified limit value, the three way catalyst (mani-
fold) malfunction is diagnosed.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Will CONSULT-III be used?
Will CONSULT-III be used?
YES >> GO TO 2.
NO >> GO TO 7.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Do not hold engine speed for more than the specified minutes below.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to the normal operating temperature.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.
6. Check that “COOLAN TEMP/S” indicates more than 70°C (158°F).
If not, warm up engine and go to next step when “COOLAN TEMP/S” indication reaches to 70°C (158°F).
7. Open engine hood.
8. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode with CONSULT-III.
9. Rev engine between 2,000 and 3,000 rpm and hold it for 3 consecutive minutes then release the acceler-
ator pedal completely.
10. Check the indication of “CATALYST”.

GENERAL MAINTENANCE
General MaintenanceINFOID:0000000003858221
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.
Item Reference page
TiresCheck the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors and the engine hood operate properly. Also make sure that
all latches lock securely. Lubricate if necessary. Make sure that the secondary
latch keeps the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lu-
brication frequently.MA-42
Tire rotationTires should be rotated every 10,000 km (6,000 miles).WT-3
Wheel alignment and
balanceIf the vehicle should pull to either side while driving on a straight and level road,
or if you detect uneven or abnormal tire wear. there may be a need for wheel
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed.
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and oth-
er lamps are all operating properly and installed securely. Also check headlamp
aim.—
Warning lamps and
chimesMake sure that all warning lamps and chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering condition, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.MA-42
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.MA-13
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the en-
gine.LU-7
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir.MA-37
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN” lines. —
