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)NeveruseCG-4oil.
l(3) Oil filter element assembly and O-ring seal are replacement parts.
l(4) First replace at 100,000 Km (60,000 miles), then every 60,000Km (36,000 miles). 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.

REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring.
lIf water drain plug on cylinder block is removed, close and tighten it. Refer toEM-110, "CYLIN-
DER BLOCK".
2. Make sure that each hose clamp has been firmly tightened.
3. Fill radiator and reservoir tank to the specified level.
lPour 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.
lUse Genuine NISSAN Anti-freeze Coolant (L250) or equiv-
alent in its quality. Refer toMA-14, "
RECOMMENDED
FLUIDS AND LUBRICANTS"
lWhen engine coolant overflows air relief hole, install air relief
plug.
4. Warm up engine to normal operating temperature without radiator cap and reservoir tank cap installed.
lIf engine coolant overflows radiator filler hole and reservoir tank filler hole, install radiator cap
and reservoir tank cap.
5. Run engine at 3,000 rpm for 10 seconds and return to idle speed with radiator cap installed.
lRepeat two or three times.
CAUTION:
Watch engine coolant temperature gauge so as not to overheat the engine.
6. Stop engine and cool down to less than approximately 50°C(122°F).
lCool down using a fan to reduce the time.
lIf necessary, refill radiator up to filler neck with engine coolant.
7. Refill reservoir tank to MAX level line with engine coolant.
8. Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.
9. Check cooling system for leaks with engine running.
10. 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.
lSound may be noticeable at heater unit.Radiator drain plug:

11. Repeat step 10 three times.

no longer drops.
FLUSHING COOLING SYSTEM
1. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap and reservoir tank cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water from the system. Refer toMA-19, "
DRAINING ENGINE COOLANT".
6. Repeat steps 1 through 5 until clear water begins to drain from radiator.
Checking Cooling SystemELS001JR
WARNING:
Never remove the radiator cap and reservoir tank cap when the engine is hot. Serious burns could
occur from high pressure engine coolant escaping from the radiator and the reservoir tank. Wrap a
thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully
remove the cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
lBe careful not to bend or damage the radiator fins.
lWhen radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
lUse compressed air lower than 490 kpa (4.9 bar, 5 kg/cm2, 71psi) and keep distance more than 30
cm(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.
CHECKING RESERVOIR TANK CAP
lInspect valve seat of reservoir tank cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.
