2012 INFINITI G-CONVERTIBLE engine coolant

8-8Maintenance and do-it-yourself
GUID-EE54D4F6-5F4A-4B0F-A147-7A9330E7ABCFThe engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
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 escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-16) of this man-
ual.
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator cap.
CAUTION
.Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
. When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to −348F (−378C). The
use of other types of coolant 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. Mixing any other type of
coolant other than Genuine 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 Main-
tenance Guide for more details.
ENGINE COOLING SYSTEM

SDI2043
CHECKING ENGINE COOLANT LEVELGUID-DA7D7105-DC17-4713-B231-B4FA68BFD877Check the coolant levelin 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
coolant, have it checked by an INFINITI
retailer.
CHANGING ENGINE COOLANTGUID-448B6596-5480-4B35-8757-8FBCB36BF623Major cooling system repairs should be
performed by an INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.
To avoid the danger of 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 the reach of children
and pets.
Engine coolant must be disposed of
properly. Check your local regulations.
Maintenance and do-it-yourself8-9

Recommended fluid is Genuine NISSAN
Windshield 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 window washer reser-
voir tank.
. Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the window washer reservoir tank.
Do not use the window washer reservoir
tank to mix the washer fluid concentrate
and water.
GUID-8579C36F-FFF9-4B84-AE07-383645D32C18.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
function 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
terminal. 5. Securely close the hood.
To connect the negative (−) battery term-
inal, perform the procedure in the follow-
ing order. Otherwise, the window and the
side roof panel may contact and be
damaged.
1. Unlock and open the driver side door.
Do not close the door.
2. Open the hood.
3. Connect the negative (−) battery term- inal. Then close the hood.
4. Fully open the driver side door window.
5. Close the driver side door and the window.
WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics, or painted surfaces. After
touching a battery or battery cap, do not
touch or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately flush
with water for at least 15 minutes and
