2018 NISSAN FRONTIER cooling

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. 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
A. 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, refer to the "Mainte-
nance 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, refer to “En-
gine compartment check locations” in this
section.
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.

CAUTION
∙ Do not ground accessories directly tothe battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
∙ Use electrical accessories with the en- gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator. The current sensor
Ais located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.

WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive
belt. The engine could rotate
unexpectedly.

or equivalent with the proper mixture. (For
additional information on the proper mix-
ture for your area, refer to “Engine cooling
system” in the “Do-it-yourself ” section of
this manual.)
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 refer
to “Recommended fluids/lubricants and
capacities” in the “Technical and consumer
information” section of this manual.
Evaporative emissions control vapor
lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally 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 immedi-
ately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
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. Tire rotation:
Tires should be rotated every
5,000 miles (8,000 km) according to the in-
structions under “Explanation of general
maintenance items” in this section. When
rotating tires, check for damage and un-
even wear. Replace if necessary.
Transmission fluid/oil, differential oil: Vi-
sually inspect for signs of leakage at speci-
fied intervals.
