GENERAL MAINTENANCE

GENERAL MAINTENANCEPFP:00000
General MaintenanceBLS0005E
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.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.—
WindshieldClean the windshield on a regular basis.
Check the windshield at least every six months for cracks or other damage.
Repair as necessary.—
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.BL-13
Tire rotationTires should be rotated every 10,000 km (6,000 miles).MA-40
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim.—
Item Reference page
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that air comes out of the defroster outlets properly and in sufficient quan-
tity when operating the heater or air conditioner.—
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-44
Accelerator pedalCheck the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.—
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep the floor mats away from the pedal.BR-6
, BR-21
Parking brakeCheck that the pedal has the proper travel.PB-2

When drain all of engine coolant in the system, open water drain plug on engine cylinder block.
Refer to EM-81, "
CYLINDER BLOCK" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-18, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-81, "
CYLINDER
BLOCK" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
5. Fill radiator and reservoir tank to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.

Use NISSAN Genuine Engine Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
6. Install air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
7. Install radiator cap.Radiator drain plug:

8. Warm up until opening thermostat and water control valve. Standard for warming-up time is approximately
10 minutes at 3,000 rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
9. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
10. Refill reservoir tank to “MAX” level line with engine coolant.
11. Repeat steps 3 through 9 two or more times with radiator cap installed until engine coolant level no longer
drops.
12. Check cooling system for leaks with engine running.
13. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
14. Repeat step 13 three times.
15. If sound is heard, bleed air from cooling system by repeating step 3 through 9 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-81, "
CYLINDER
BLOCK" .
2. Remove air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
3. Disconnect heater hose (left side of vehicle) at the position in
the figure.

Enhance heater hose as high as possible.
4. Fill radiator and reservoir tank with water and reinstall radiator cap.

When engine coolant overflows disconnected heater hose, connect heater hose, and continue filling the
engine coolant.
5. Install air duct assembly. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
6. Run engine and warm it up to normal operating temperature.
7. Rev engine two or three times under no-load.
8. Stop engine and wait until it cools down.
9. Drain water from the system. Refer to MA-16, "
DRAINING ENGINE COOLANT" .
10. Repeat steps 1 through 9 until clear water begins to drain from radiator.
Checking Cooling SystemBLS00093
WARNING:

Do not remove radiator cap when the engine is hot. Serious burns occur from high-pressure
engine coolant escaping from radiator.Radiator drain plug:

Checking Drive BeltsBLS0005J
WARNING:
Be sure to perform the following when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection at a point on the belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.

Adjust if belt deflection exceeds the limit.
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Release the tension by loosing lock nut and turning adjust-
ing bolt when adjusting the belt. Tighten once the lock nut
at 4.9 N·m (0.50 Kg-m, 43 in-lb). Then, adjust the belt ten-
sion by loosing lock nut between 45° and 90°.
Belt Deflection
Tension AdjustmentBLS0005K
CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection of belt being used exceeds “Limit”, adjust it to value for “After adjustment”.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation
in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley groove.

Keep engine oil, working fluid and engine coolant away from belt.

Do not twist or bend belt excessively.
