2019 INFINITI Q70 engine coolant

The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The main-
tenance schedule indicates at which mile-
age/time intervals 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” (P.9-2).
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 re-
quired.
When applicable, additional information can
be found in the “8. Do-it yourself” section of
this manual.
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
validated by INFINITI.
For recommended fuel, lubricants, fluids,grease, and refrigerant, refer to “Capacities
and recommended fluids/lubricants” (P.10-
2) of this manual.
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 NISSAN Long Life Anti-
freeze/Coolant (blue) or equivalent with the
proper mixture. (Refer to “Engine cooling
system” (P.8-8) to determine the proper
mixture for your area.)
NOTE:
Mixing any other type of coolant or the use
of non-distilled water may reduce the
recommended service interval of the cool-
ant.
Engine oil and oil filter:
Replace engine oil and oil filter at the
specified intervals. For recommended oil
grade and viscosity refer to “Capacities and
recommended fluids/lubricants” (P.10-2).
Engine valve clearance*:
Inspect only if valve noise increases. Adjust
valve clearance if necessary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as
necessary.
Fuel lines*:
Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tight-
en connections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.
CHASSIS AND BODY MAINTE-
NANCE
Brake lines and cables:
Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.

NOTE:
(1) After 40,000 miles (64,000 km) or 48
months, inspect every 10,000 miles
(16,000 km) or 12 months. Replace the
drive belts if found damaged.
(2) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000
miles (168,000 km) or 84 months. After first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill cool-
ant.
(6) Periodic maintenance is not required.
However, if valve noise increases, inspectvalve clearance.
*: Maintenance items and intervals with “*”
are recommended by INFINITI for reliable
vehicle operation. The owner need not to
perform such maintenance in order to
maintain the emission warranty or manu-
facturer recall liability. Other maintenance
items and intervals are required.
