2023 NISSAN ALTIMA refrigerant type

NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capaci-
ties” (P. 10-2).
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 inter-
vals. 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 replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-5).
NOTE: Mixing any other type of coolant
or the use of non-distilled water may re-
duce the recommended service interval
of the coolant.
Engine oil and oil filter:
Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
Engine valve clearance*: Inspect only if
valve noise increases. Adjust valve clear-
ance if necessary.
Fuel tank vapor vent system*: Check va-
por lines for leaks or looseness. Tighten
connections or replace parts as necessary.
Fuel filter: Periodic maintenance is not re-
quired. (in-tank type filter)
Fuel lines/connections*: Check the fuel
hoses, piping and connections for leaks,
looseness, or deterioration. Tighten con-
nections or replace parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the type as originally
equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake pads and rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts
immediately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
Propeller shaf t(s): Check for damage,
looseness, and grease leakage. (AWD)
In-cabin microfilter: Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Steering gear and linkage, axle and sus-
pension parts, drive shaf t boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.

Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life. Damage to the engine caused
by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is
not covered by the NISSAN New Vehicle
Limited Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at coldoutside temperatures
• driving in dusty conditions
• extensive idling
• stop and go commuting
For additional information, see the “Mainte-
nance and schedules” (P. 9-2).
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG
(VC100YF oil) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air
conditioning system and will require
the replacement of all air conditioner
system components.
The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner sys-
tem should only be serviced by trained and
certified technicians to ensure proper and
safe operation (SAE J2845). A NISSAN dealer
has the trained technicians and equip-
ment needed to recover and recycle your
air conditioner system refrigerant. Only new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit a NISSAN dealer
when servicing your air conditioner
system.
