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.

Fluids and LubricantsELS001JA
*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine NISSAN Anti-freeze Coolant (L250) 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.
*4: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRON
™III/MER-
CON™ Automatic Transmission Fluid.
*5:Using automatic transmission fluid other than Genuine NISSAN ATF Matic Fluid J will cause deterioration in driveability
and automatic transmission durability, and may damage the automatic transmission, which is not covered by the warranty.
*6: DEXRON™III type ATF can be used.
*7: Never mix different types of fluids (DOT 3 and DOT 4).Capacity (Approximate)

RECOMMENDED FLUIDS AND LUBRICANTS
Engine Coolant Mixture Ratio
ELS001JC
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, additional cooling system
additives are not necessary.
CAUTION:
lWhen adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant (L250) or equivalent in its
quality. Because L250 is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.
lWhen checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant
temperature.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

Changing Engine CoolantELS001JQ
WARNING:
lTo avoid being scalded, do not change engine coolant when engine is hot.
lWrap a thick cloth around cap and carefully remove radiator cap. First, turn radiator cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and
remove radiator cap.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
When draining all engine coolant in the system, also perform the following steps.
2. Remove air relief plug (1) on heater feed tube.

4. Remove reservoir tank, drain engine coolant, then clean reservoir tank.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system. Refer toMA-21, "

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.

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. 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.
