cooling INFINITI QX30 2018 Owner's Guide

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.
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 connec-
tions.
Underbody:
The underbody is frequently exposed to cor-
rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, 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
accumulate. For additional information, see
"Cleaning exterior".
Windshield washer fluid*:
Check that there is adequate fluid in the res-
ervoir.The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
"General maintenance" in this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your vehicle. Other
maintenance items and intervals are required.
When applicable, additional information can
be found in the “Do-it-yourself” section in
Chapter 8.
NOTE
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to "Recom-
mended fluids/lubricants and capacities".
EMISSION CONTROL SYSTEM
MAINTENANCE
Drive belts*:
Check engine drive belts for wear, fraying or
cracking and for proper tension. Replace any
damaged drive belts
Engine air filter*:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
check/replace the filter more frequently.
Engine coolant*:
Replace coolant at the specified interval.
When adding or replacing coolant, be sure to
use only Genuine INFINITI Engine Coolant or
equivalent in its quality (BASF Glysantin®
G40®). (For additional information, refer to
"Engine cooling system".)
NOTE
Mixing any other type of coolant or the use
of non-distilled water may reduce the rec-
ommended service interval of the coolant.
