2019 INFINITI Q50 coolant reservoir

CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by an INFINITI retailer.
The service procedures can be found in the
appropriate INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
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 prop-
erly. Check your local regulations. The intercooler cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round anti-freeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional inter-
cooler cooling system additives are not
necessary.
WARNING
.
Never remove the coolant reservoir
cap when the engine is hot. Wait until
the engine cools down. Serious burns
could be caused by high pressure fluid
escaping from the coolant reservoir.
. The intercooler reservoir is equipped
with a pressure type cap. To prevent
engine and intercooler damage, use
only a genuine NISSAN intercooler
reservoir cap.
CAUTION
.Never use any additives in the cool-
ant such as radiator sealer in the
cooling system. This may cause da-
mage to the intercooler. .
When adding or replacing coolant, be
sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to −34°F(−37°C). If additional
freeze protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) con-
centrate following the directions on
the container. If an equivalent cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is
used, follow the coolant manufac-
ture’s instructions to maintain mini-
mum antifreeze protection to −34°F
(−37°C). The use of other types of
coolant solutions other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent may damage
the Intercooler cooling system.

CHECKING INTERCOOLER
COOLANT LEVEL
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is
below the MIN level
, add coolant to the
MAX level.
If the intercooler cooling system frequently
requires coolant, have it checked. It is
recommended you visit an INFINITI retailer
for this service.
CHANGING INTERCOOLER
COOLANT
Intercooler coolant is maintenance-free.
If replacement is required, it is recommended
you visit an INFINITI retailer for this service.
Improper servicing can result in intercooler
overheating.
WARNING
. To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
. Never remove the cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the intercooler cooling re-
servoir.
. 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
children and pets.
Intercooler coolant must be disposed of
properly. Check your local regulations.

To check the window washer fluid level, use
your finger to plug the holeof the cap/
tube assembly, then remove it from the
reservoir. If there is no fluid in the tube,
add fluid.
Add a washer solvent to the washer for
better cleaning. In the winter season, add a
windshield washer antifreeze. Follow the
manufacturer’s instructions for the mixture
ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of window washer fluid.
Recommended fluid is Genuine NISSAN
Windshield 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 re-
servoir with washer fluid concen-
trates at full strength. Some methyl
alcohol based washer fluid concen-
trates may permanently stain the
grille if spilled while filling the win-
dow washer reservoir. .
Pre-mix washer fluid concentrates
with water to the manufacturer’s
recommended levels before pouring
the fluid into the window washer
reservoir. Do not use the window
washer reservoir 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 dis-
charging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
WARNING
. Do not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by the battery is explosive.
Do not allow battery fluid to contact
your skin, eyes, fabrics, or painted

9-4Maintenance and schedules
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
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
under severe condition require frequent
checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.) 2.
Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
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.
Intercooler 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. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4).)
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 corrected 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, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
