2010 INFINITI G37 engine coolant

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● Never remove the radiator cap when the en-
gine is hot. Wait until the engine and radia-
tor cool down. Serious burns could be
caused by high pressure fluid escaping from
the radiator. See precautions in “IF YOUR
VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
● 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 (blue) or equivalent with
the proper mixture ratio shown in the follow-
ing chart. The life expectancy 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 expectancy of the factory-fill coolant. Re-
fer to the Infiniti Service and Maintenance
Guide for more details. The use of other
types of coolant solutions may damage the
engine cooling system.
● The coolant reservoir is equipped with a
pressure type radiator cap. To prevent en-
gine damage, use only a genuine NISSAN
coolant reservoir cap.

engine is cold. If the coolant level is below MIN
 2
, open the reservoir tank cap and add coolant
up to the MAX

level. 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

Tighten the cap securely after adding engine
coolant.

(168,000 km) or 7 years. Mixing any other type
of coolant 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.
If the cooling system requires coolant fre-
quently, 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● To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap when the en-
gine 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 reach of children and
pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL 1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
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
 1
.
If the oil level is below
 2
, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill

WARNINGAntifreeze is poisonous and should be stored
carefully in marked containers out of the reach
of children.
Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manufac-
turer’s instructions for the mixture ratio. Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield 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 win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water. ● 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.
COUPE CAUTIONWhen the battery cable is removed from the
battery terminal, do not close either of front
doors. The automatic window adjusting func-
tion 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 termi-
nal.
5. Securely close the hood.SDI2027

A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Push the ignition switch to the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/M test condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
If the MIL indicates the vehicle is in a “not
ready” condition, drive the vehicle through the
following pattern to set the vehicle to the
“ready condition”. If you cannot or do not want
to perform the driving pattern, an INFINITI re-
tailer can conduct it for you.
WARNINGAlways drive the vehicle in a safe and prudent
manner according to traffic conditions and
obey all traffic laws.
1. Start the engine. Allow the engine to idle
until the engine coolant temperature
gauge needle points between the C and H
(normal operating temperature).
2. Accelerate the vehicle to 55 MPH (88
km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 10 seconds.
3. Quickly depress the accelerator pedal for
a moment, then drive the vehicle at a
speed of 53 to 60 MPH (86 to 96 km/h) for
at least 9 minutes.
4. Stop the vehicle. Leave the engine run-
ning. 5. Accelerate the vehicle to 55 MPH (88
km/h) and maintain the speed for 2 min-
utes.
6. Repeat steps 4 and 5 at least 10 times.
7. Quickly release the accelerator pedal
completely and keep it released for at
least for 1 minute. Maintain the speed for
at least 5 minutes.
8. Stop the vehicle. Place the automatic
transmission selector lever in the P (Park)
or N (Neutral) position or the manual
transmission shift lever in the N (Neutral)
position.
9. Turn the engine off.
10. Start the engine and allow the engine to
idle for at least 2 hours.
11. Place the ignition switch to the OFF posi-
tion and leave the vehicle for at least 90
minutes.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is ac-
ceptable between steps. Do not stop the engine
until step 7 is completed.READINESS FOR INSPECTION/
