NOTE: (1) Oil filter element assembly and O-ring seal are replacement parts.
(2) First replace at 90,000 km (54,000 miles), then every 60,000 km (36,000 miles). Perform ªIº (Checking the mixture
ratio and correcting the mixture ratio if necessary) at the middle of replacement interval.
(3) If engine power decreases, black exhaust smoke is emitted or engine noise increases, check injection nozzles and,
if necessary, replace injection nozzle assembly.
(4) If valve noise increases, check valve clearance.
HMaintenance items with ªHº should be performed more frequently according to ªMaintenance under severe driv-

*3: Never use API CG-4.
*4: Use Genuine Nissan Anti-freeze Coolant (L2N) or equivalent in its quality, in order to avoid possible aluminum corrosion within the engine cooling
system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be covered by
the warranty even if such incidents occurred during the warranty period.
*5: Never mix DOT 3 & DOT 4.

Engine Coolant Mixture Ratio
The engine cooling system is filled at the factory with a high-
quality, year-round and extended life engine coolant. The high
quality engine coolant contains the specific solutions effective for
the anti-corrosion and the anti-freeze function. Therefore, addi-
tional cooling system additives are not necessary.
CAUTION:
+When adding or replacing coolant, be sure to use only
Genuine Nissan Anti-freeze Coolant (L2N) or equivalent.
Because L2N is premixed type coolant (Mixture ratio
50%).
The use of other types of engine coolant may damage your
cooling system.
+When checking the engine coolant mixture ratio by the cool-
ant hydrometer, use the chart below to correct your hydrom-
eter reading (specific gravity) according to coolant tempera-
ture.

WARNING:
Never remove the radiator cap when the engine is hot. Seri-
ous burns could be caused by high pressure fluid escaping
from the radiator. Wait until the engine and radiator cool
down.

Pour coolant through coolant filler neck slowly to allow air
in system to escape.
11. Install radiator cap (side with pressure valve).
12. Warm up engine to normal operating temperature.
13. Run engine at 2,000 rpm for 10 seconds and return to idle
speed.
+Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
14. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
15. Remove the reservoir tank filler cap (side with pressure
valve) and check coolant level.
+If necessary, refill reservoir tank (side with pressure valve) up
to filler neck with coolant.
16. Refill reservoir tank to Max line with coolant.
17. Repeat step 10 through step 16 two or more times.
18. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 2,000 rpm with heater tem-
perature control set at several positions between COOL and
HOT.
+Sound may be noticeable at heater water cock.
19. If sound is heard, bleed air from cooling system by repeat-
ing steps 12 through 18 until coolant level no longer drops.
+Clean excess coolant from engine.
Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap (side with pressure valve) with
cap tester to see if it is satisfactory.
Radiator cap relief pressure:
59-98kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
2,9-14psi)

Pull the negative-pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Use of higher pressure than the specified value may cause
damage to radiator.
Checking and Replacing Fuel Filter and
Draining Water
Be careful not to spill fuel in engine compartment. Place a
rag to absorb fuel.
CHECKING FUEL FILTER
Check fuel filter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.
2. Remove fuel filter using band-type filter wrench.
3. Remove fuel filter and fuel filter sensor.
CAUTION:
Remove fuel filter without spilling fuel. If spilt, wipe off
immediately. Be specially careful not to spill fuel on engine
mount insulator.

Checking A/T Fluid
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid tempera-
tures of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº range on
dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in ªPº position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of
either range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side
of range, add fluid to the charging pipe.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80ÉC (122
to 176ÉF) using ªHOTº range on dipstick.
CAUTION:
Securely install A/T fluid level gauge.
6. Check fluid condition.
+If fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair
of A/T.
+If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to LC section
(ªRadiatorº, ªENGINE COOLING SYSTEMº).
