Removal and InstallationEBS01E5C
CAUTION:
lBe careful not to get burned when engine oil and engine coolant are hot.
lWhen removing, prepare a shop cloth to absorb any engine oil and engine coolant leakage or spill-
age.
lCompletely wipe off any engine oil and engine coolant that adhere to engine and vehicle.
REMOVAL
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove engine undercover front and engine undercover middle. Refer toEI-15, "
FRONT BUMPER".
2. Drain engine coolant from radiator and cylinder block. Refer toCO-7, "
Changing Engine Coolant"and
EM-110, "
CYLINDER BLOCK".
NOTE:
Perform this step when removing water hoses and water connector.
1. Gasket 2. Water hose connector 3. Water hose
4. Water hose 5. Connecting bolt 6. Washer
7. Oil cooler 8. O-ring 9. Oil filter bracket
A. To cylinder block B. To heater return pipe Vehicle front

3. Remove mounting nuts (2) of fuel filter (1), and move it aside
with its hoses connected. Temporarily secure it with a rope to
avoid putting load on its hose.
4. Disconnect water hoses from oil cooler.
lWhen removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant spilling.
CAUTION:
lPerform this step when engine is cold.
lDo not spill engine coolant on drive belts.
5. Loosen connecting bolt and remove oil cooler.
CAUTION:
Do not spill engine oil and engine coolant to rubber parts such as drive belts and engine mounting
insulator.
6. Remove water hoses and water connector, as necessary.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler.
INSTALLATION
Installation is the reverse order of removal.
lMake sure that no foreign objects are adhering to the installation planes of oil cooler or oil filter bracket.
lTighten the connecting bolt after aligning the stopper on the oil
filter bracket side with protrusion of oil cooler (1).
lInstall fuel filter (1), and tighten mounting nuts (2) to the speci-
fied torque.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and add engine oil and engine coolant. Refer to
LU-5, "
ENGINE OIL"andCO-7, "ENGINE COOLANT".

General MaintenanceELS001HT
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 periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. 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, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure 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
lubrication frequently.MA-39
,BL-12
Tire rotationTires should be rotated every 10,000 km (6,000 miles) for 2WD models and
every 5,000 km (3,000 miles) for 4WD models.MA-34
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check
headlamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, 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-40
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-19
(YD25DDTi)
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-25
(YD25DDTi)
Brake and clutch fluid
levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.MA-28
,MA-35
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines.—

Periodic MaintenanceELS001J9
The following tables show the normal maintenance schedule. Depending upon weather and atmospheric con-
ditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent mainte-
nance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
ENGINE AND EMISSION CONTROL MAINTENANCE (YD25DDTI DIESEL ENGINE)
(Annual Mileage <30,000 Km/year)
Abbreviations: I = Inspect and correct or replace as necessary, R = Replace, D = Check filter and drain water
NOTE:
lMaintenance items with “ ” should be performed more frequently according to “Maintenance Under Severe Driving
Conditions”.
l(1) If valve noise increases, check valve clearance.
l(2) Never use CG-4 oil.
l(3) Oil filter element assembly and O-ring seal are replacement parts.
l(4) First replace at 100,000 Km (60,000 miles)/60 months, then every 60,000Km (36,000 miles)/36 months. After first
replacement, perform "I" (checking the mixture ratio and correcting the mixture ratio if necessary) at the middle of
replacement interval.
l(5) If engine power decreases, black exhaust smoke is emitted or engine noise increases, perform this maintenance item. MAINTENANCE OPERATIONMAINTENANCE INTERVAL
