engine overheat INFINITI M 2010 User Guide

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.

cIf a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient data is not available to ensure that all
methanol blends are suitable for use in
INFINITI vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refueling.
Gasoline containing oxygenates can cause paint
damage.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended can cause persistent,
heavy ªspark knockº. (Spark knock is a metallic
rapping noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy spark
knock even when using gasoline of the stated
octane rating, or if you hear steady spark knock
while holding a steady speed on level roads,
have an INFINITI retailer correct the condition.
Failure to correct the condition is misuse of the
vehicle, for which INFINITI is not responsible.
Incorrect ignition timing will result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or enginedamage. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is not a cause for con-
cern, because you get the greatest fuel benefit
when there is light spark knock for a short time
under heavy engine load.
CAUTION
c
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
c E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
c U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.
