8-6Maintenance and do-it-yourself

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine NISSAN
Long Life Antifreeze/Coolant (blue) and 50% water
to provide year-round anti-freeze and coolant pro-
tection. The antifreeze solution contains rust and
corrosion inhibitors. Additional engine cooling
system additives are not necessary.
WARNING
●Never remove the radiator or coolant reservoir
cap when the engine is hot. Wait until the
engine and radiator cool down. Serious burns
could be caused by high pressure fluid escap-
ing from the radiator. See precautions in “IF
YOUR VEHICLE OVERHEATS” in the “6. In case
of emergency” section of this manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.
CAUTION
●When adding or replacing coolant, be sure to
use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent. Genu-
ine NISSAN Long Life Antifreeze/Coolant (blue)
is pre-diluted to provide antifreeze protection
to 34°F (37°C). If additional freeze protec-
tion is needed due to weather where you oper-
ate your vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) concentrate fol-
lowing the directions on the container. If an
equivalent coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s instructions
to maintain minimum antifreeze protection to
34°F (37°C). The use of other types of cool-
ant solutions other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system.
●The life expectancy of the factory-fill coolant
is 105,000 miles (168,000 km) or 7 years. Mix-
ing any other type of coolant other than Genu-
ine NISSAN Long Life Antifreeze/Coolant
(blue), including Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. Refer to the INFINITI
Service and Maintenance Guide for more
details.
CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level
2, open the reservoir tank
cap and add coolant up to the MAX level
1.If
the reservoir tank is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fill
the radiator with coolant up to the filler opening
and also add it to the reservoir tank up to the
MAX level
1.
Tighten the cap securely after adding engine
coolant.
If the cooling system frequently requires cool-
ant, have it checked by an INFINITI retailer.

ENGINE COOLING SYSTEM
Maintenance and do-it-yourself8-7

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap when the en-
gine 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 the reach of children and
pets. Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill

8-8Maintenance and do-it-yourself

Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap and pour the window washer fluid into the
reservoir opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manufac-
turer’s instructions for the mixture ratio.
Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Antifreeze
or equivalent.
CAUTION
●
Do not substitute engine anti-freeze coolant
for window washer solution. This may result
in damage to the paint.
● Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water. ●
Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative () battery
terminal cable to prevent discharging it.
CAUTION
When the battery cable is removed from the
battery terminal, do not close either of front
doors. The automatic window adjusting func-
tion will not work, and the side roof panel may
be damaged.
To disconnect the negative () battery terminal,
perform the procedure in the following order.
Otherwise, the window and the side roof panel
may contact and be damaged.
1. Close the windows.
2. Open the hood.
3. Close and lock all the doors.
4. Disconnect the negative () battery termi- nal.
