Oil Filter or equivalent.

Be careful not to get burned when engine and engine oil
may be hot.

When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.

Do not allow engine oil to adhere to drive belt.

Completely wipe off any engine oil that adheres to engine
and vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.

Checking and Changing Spark PlugsELS000ZK
REMOVAL
1. Remove ignition coil. Refer to EM-31, "IGNITION COIL" .
2. Remove spark plug with spark plug wrench (commercial service
tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL (EXCEPT FOR RUSSIA)
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution

Check plug gap of each spark plug.

If out of standard, adjust or replace spark plug.

Use a wire brush for cleaning, if necessary.Oil filter:

Checking Drive BeltsELS000CC

Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

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

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

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentELS000K5
Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

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

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant etc.

Do not twist or bend the belts with strong force.

Changing Engine CoolantELS000CD
WARNING:

To avoid being scalded, never change the engine coolant when the engine is hot.

Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Remove engine undercover.
2. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
CAUTION:

Be careful not to allow engine coolant to contact drive
belts.

Cover the exhaust tube heat shield to prevent from
splashing engine coolant.Nut A:

When draining all engine coolant in the system, open water drain plug on engine cylinder block.
Refer to EM-231, "
DISASSEMBLY".
3. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer to MA-32, "
FLUSHING COOLING SYSTEM" .
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.

If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-235, "ASSEM-
BLY" .
2. Remove air relief plug.
3. Fill radiator and reservoir tank to the 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 Genuine NISSAN Anti-freeze Coolant or equivalent
mixed with water (distilled or demineralized). Refer to
MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS".

When engine coolant overflows air relief hole, install air relief
plug with new copper washer.
4. Install radiator cap.
5. 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.
6. Stop engine and cool down to less than approximately 50°C(122°F).

Cool down using a fan to reduce the time.

If 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”.

Sound may be noticeable at heater unit.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating steps 3 through 6 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-235, "ASSEM-
BLY" .
2. 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.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water from the system. Refer toMA-30, "
DRAINING ENGINE COOLANT" .
7. Repeat steps 1 through 6 until clear water begins to drain from radiator.
Checking Cooling SystemELS000C4
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine coolant escaping from the radiator. 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.

Be careful not to bend or damage the radiator fins.

When 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.

Use 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 RADIATOR CAP

Check valve seat of radiator 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.

Pull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter (special
service tool), apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
CHECKING RADIATOR SYSTEM FOR LEAKS

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (special service tool).
WARNING:
Never remove the radiator cap when the engine is hot. Seri-
ous burns could occur from high pressure engine coolant
escaping from the radiator.
CAUTION:
Higher test pressure than specified may cause radiator
damage.
