The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
WARNING
cNever remove the radiator or coolant reser-
voir 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 ªIF YOUR VEHICLE OVERHEATSº in the ª6.
In case of emergencyº section of this
manual.
c 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 a Genuine NISSAN Long Life
Antifreeze/Coolant (green) or equivalent with
the proper mixture ratio of 50% antifreeze and
50% demineralized or distilled water. The use
of other types of coolant solutions may damage
the engine cooling system.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when the
engine is cold. If the coolant level is below the
MIN level
s1, open the reservoir cap and add
coolant up to the MAX level
s2. If the reservoir
is empty, check the coolant level in the radiator
when the engine is cold.
For VK45DE engine model, remove the engine
cover by removing the 4 clips
sA.
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
s2.
If the cooling system frequently requires cool-
ant, have it checked by an INFINITI retailer.
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
c To avoid the danger of being scalded, never
change the coolant when the engine is hot.
c Never remove the radiator cap when the en-
gine is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
c Avoid direct skin contact with used coolant.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
c Keep coolant out of reach of children and
pets.
Engine coolant must be disposed of properly.
Check your local regulations.

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
s1.
If the oil level is below
s2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
s3.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil mainte-
nance intervals or during the break-in period,

filling the engine with oil.
See ªCAPACITIES AND RECOMMENDED
FUEL/LUBRICANTSº in the ª9. Technical and
consumer informationº section for drain and refill capacity. The drain and refill capacity
depends 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.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
