2011 INFINITI EX coolant temperature

Warning lights and chimes:Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily. Engine oil level*:
Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI retailer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from
the air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes are
evident, check for the cause and have it cor-
rected immediately.
Power steering fluid level* and lines: Check the
level when the fluid is cold, with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections. Underbody:
The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
8-4Maintenance and do-it-yourself

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 engine
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
3.
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,
depending on the severity of operating condi-
tions.
CAUTION
Oil level should be checked regularly. Operat-
ing the engine with an insufficient amount of oil
can damage the engine, and such damage is
not covered by warranty.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn the engine off and wait more than 15 minutes.
4. Raise and support the vehicle using a suitable floor jack and safety jack stands.
●Place the safety jack stands under the
vehicle jack-up points.
● A suitable adapter should be attached to
the jack stand saddle.
