engine NISSAN MURANO 2003 1.G Manual PDF

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized
water/distilled water. The use of other
types of coolant solutions may damage
your engine cooling system.Outside temperature

WARNING

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

See “If your vehicle overheats” in the
“6. In case of emergency” section.

The radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX level. If
the reservoir tank is empty, add the coolant to
the reservoir tank up to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

CHANGING ENGINE COOLANTContact your NISSAN dealer if replacement is
required.

Major cooling system repairs should be per-
formed by your NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.

Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

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

Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.
CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Rein-
sert it all the way.5. Remove the dipstick again and check the oil
level. It should be between the H and L
marks. If the oil level is below the L mark,
remove the oil filler cap and pour recom-
mended oil through the opening.Do not
overfill.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.

temperature.
3. Turn the engine off andwait more than 10
minutes.
4. Place a large drain pan under the drain plug.
5. Remove the oil filler cap.6. Remove the drain plug with a wrench and
completely drain the oil.
If oil filter is to be changed, remove and
replace it at this time. See later in “Engine oil”
for changing engine oil filter.

stall the cap securely.
CAUTION
Never pull out the oil level gauge while
filling engine oil.
See “Capacities and recommended
fuel/lubricants” in the “9. Technical and con-
sumer information” section for drain and refill
capacity. The drain and refill capacity de-
pends on the oil temperature and drain time.
Use these specifications for reference only.
Always use the dipstick to determine the
proper amount of oil in the engine.
9. Start the engine.
Check for leakage around the drain plug.
Correct as required.
10.Turn the engine off andwait more than 10

Contact your NISSAN dealer if checking or
replacement is required.
CAUTION

Use only Genuine NISSAN CVT Fluid
NS-2. Do not mix with other fluids.

Using transmission fluid other than
Genuine NISSAN CVT Fluid NS-2 will
damage the CVT transmission, which
is not covered by the NISSAN new
vehicle limited warranty.
The specified CVT fluid is also described on
caution labels located in the engine compart-
ment.Check the fluid level in the reservoir tank.
The fluid level should be checked using the HOT
range at fluid temperatures of 122 to 176°F (50
to 80°C) or using the COLD range at fluid
temperatures of 32 to 86°F (0 to 30°C).
CAUTION

Do not overfill.

Use Genuine Nissan PSF or equiva-
lent.Check the fluid level in the reservoir. If the fluid is
below the MIN line or the brake warning light
comes on, addDOT 3fluid up to the MAX line.
If fluid must be added frequently, the system
should be thoroughly checked by your NISSAN
dealer.
WARNING
Use only new fluid. Old, inferior, or con-
taminated fluid may damage the brake
system. The use of improper fluids can
damage the brake system and affect the

CAUTION
Do not spill the fluid on painted sur-
faces. This will damage the paint. If fluid
is spilled, wash with water.
Add fluid when the low washer fluid warning light
comes on. Add a washer solvent to the water for
better cleaning. In the winter season, add a
windshield washer anti-freeze. Follow the manu-
facturer’s instructions for the mixture ratio.
WARNING
Anti-freeze is poisonous and should be
stored carefully in marked containers
out of the reach of children.
CAUTION
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt is not necessary to replace the platinum-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance schedule but, do not
reuse them by cleaning or regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, push
down the lock pins

The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the separate Service and Mainte-
nance Guide. When replacing the filter, wipe the
inside of the air cleaner housing and the cover
with a damp cloth.

cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.

Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
CAUTION

After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when
the engine hood is opened.

Make sure the wiper blade contacts
the glass, otherwise the arm may be
damaged from wind pressure.

Worn windshield wiper blades can
damage the windshield and impair
driver vision.CLEANINGIf your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your wind-
shield is clean if beads do not form when rinsing
with clear water.
Clean the blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Thenrinse the blade with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.WINDSHIELD WIPER BLADES
