2023 NISSAN FRONTIER Owners Manual

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
OB, add coolant
to the MAX level
OA. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, see the "Maintenance
and schedules" section of this manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-4).
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
• Never remove the radiator or engine
coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing 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 the reach of chil-
dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
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 between the H
(High) and L (Low) marksOB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
OA,re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
overfill
OC.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the en-
gine, and such damage is not covered
by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil
and oil filter change, refer to the instruc-
tions outlined in this section.
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 for 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.

Engine oil and filter
1. Place a large drain pan under the drain plug and oil filter.
2. Remove the oil filler cap.
3. Remove the drain plug with a wrench by turning it counterclockwise and com-
pletely drain the oil.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
• Prolonged and repeated contact
with used engine oil may cause skin
cancer.
• Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep used engine oil out of reach of
children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket ma-
terial remaining on the sealing surface
of the engine. Failure to do so could
lead to an oil leak and engine damage. •
The dipstick must be inserted in
place to prevent oil spillage from the
dipstick hole when filling the engine
with oil.
6. Coat the gasket on the new filter with clean engine oil.
It is recommended that you use a
Genuine NISSAN oil filter or equivalent,
visit your NISSAN dealer parts depart-
ment for proper part.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten addi-
tionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 f t-lb (15 to 21 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench. Do not use exces-
sive force.
Drain plug tightening torque: 22 to 29 f t-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recommended oil through the oil filler opening, and in-
stall the oil filler cap securely.

CAUTION
Do not spill fluids on engine cover. This
could damage the engine cover. If flu-
ids are spilled, immediately clean sur-
face with a neutral detergent. Do not
use an organic solvent such as brake
cleaner.
For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The
drain and refill capacity depends on the oil
temperature and drain time. Use these
specifications for reference only. Always
use the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add en-
gine oil if necessary.Af ter the operation
1. Reinstall engine protectors in reverse or-der of removal.
2. Lower the vehicle carefully to the ground.
3. Reset the oil and oil filter maintenance reminder. For additional information,
see “Vehicle information display” (P. 2-22).
• Dispose of waste oil and filter properly.
• Check your local regulations. When checking or replacement is required,
it is recommended that you visit a NISSAN
dealer for this service.
CAUTION
• NISSAN recommends using Genuine
NISSAN Matic P ATF. Do not mix with
other fluids.
• Do not use CVT fluid or manual trans-
mission fluid in this transmission.
Damage caused by the use of fluids
other than as recommended is not
covered under NISSAN’s New Vehicle
Limited Warranty.
• Using fluids that are not equivalent
to Genuine NISSAN Matic P ATF may
also damage the transmission. Dam-
age caused by the use of fluids other

AUTOMATIC TRANSMISSION FLUID
(ATF)
Do-it-yourself8-13

Check the power steering fluid level when
the engine is stopped.
The fluid level should be between the COLD
MAX line and the COLD MIN line on the
power steering fluid reservoir at cold fluid
temperatures of 32° - 86°F (0° - 30°C) or at
the HOT MAX line on the power steering
fluid reservoir at hot fluid temperatures of
122° - 176°F (50° - 80°C).If the fluid is cold and is at or below the
COLD MIN line, add Genuine NISSAN PSF-II
or equivalent to the COLD MAX line. If the
fluid is hot and below the HOT MAX line, add
Genuine NISSAN PSF-II or equivalent to the
HOT MAX line. Remove the cap and fill
through the opening.
CAUTION
• DO NOT OVERFILL.
• Do not reuse power steering fluid.
• Recommended fluid is Genuine
NISSAN PSF-II or equivalent For additional brake fluid specification in-
formation, see “Recommended fluids/
lubricants and capacities” (P. 10-2).
WARNING
• Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can dam-
age the brake system and affect the
vehicle's stopping ability.
• Clean the filler cap before removing.
• Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.
