CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir
when the engine is cold. If the coolant
level is below the MIN level
O
B
, add coolant
to the MAX level
O
A
.
If the reservoir 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 up to the MAX level
O
A
. Start the
engine and allow the engine coolant tem-
perature gauge to rise until it reaches nor-
mal operating temperature. For additional
information, see “Engine coolant tempera-
ture gauge” (P. 2-6). Turn off the engine once
the engine coolant temperature has
reached normal operating range. Allow the
engine coolant to cool to ambient tem-
perature. Recheck the coolant level in the
reservoir and add coolant to the MAX level if
necessary.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, see "Maintenance and
schedules" (P. 9-2).
For additional information on the location
of the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-3).
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN 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 engine is hot. Serious burns could
be caused by high pressure fluid es-
caping 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 chil-
dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
