NISSAN 2015 Altima Sedan - Owner's Manual - Manual (Page 368)

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Engine Coolant (blue) and 50% water
to provide year-round antifreeze 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 escaping from
the radiator. For additional information,
refer to the precautions in “If your ve-
hicle overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine 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 dam-
age 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
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to
-34° F (-37° C). If additional freeze pro-
tection 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
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C). 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 cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue), includ-
ing
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. Refer to the NISSAN Service and
Maintenance Guide for more details.
