2020 NISSAN 370Z engine overheat

6-18In case of emergency
2. Turn off the air conditioner. Open allthe windows, move the heater or air
conditioner temperature control to
maximum hot and fan control to high
speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approxi-
mately 1,500 rpm) until the tempera-
ture gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from
the radiator before opening the hood.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check if the cooling fan is running. The radiator hoses and ra-
diator should not leak water. If coolant
is leaking or the cooling fan does not
run, stop the engine.
WARNING
Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, engine
belts or the engine cooling fan. The
engine cooling fan can start at any
time.
7. After the engine cools down, check the coolant level in the reservoir with
the engine running. Add coolant to
the reservoir if necessary. Have your
vehicle repaired. It is recommended
you visit a NISSAN dealer for this
service.

8-4Do-it-yourself
The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round anti-freeze and coolant pro-
tection. The antifreeze solution contains
rust and corrosion inhibitors. Additional
engine cooling system additives are not
necessary.
WARNING
.Never remove the radiator or
coolant reservoir cap when the
engine is hot. Wait until the en-
gine and radiator cool down.
Serious burns could be caused
by high pressure fluid escaping
from the radiator. See precau-
tions in “If your vehicle overheats”
(P.6-17) of this manual.
. The radiator is equipped with a
pressure type radiator cap. To
prevent engine damage, use only
a genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system
additives such as radiator sealer.
Additives may clog the cooling
system and cause damage to
the engine, transmission and/or
cooling system.
. When adding or replacing cool-
ant, be sure to use only Genuine
NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent. Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) is pre-diluted to
provide antifreeze protection to
−34°F (−37°C). If additional freeze
protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue)
concentrate following the direc-
tions on the container. If an
equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain mini-
mum antifreeze protection to
−34°F (−37°C). The use of other
types of coolant solutions other
than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent may damage the en-
gine cooling system.
. The life expectancy of the fac-
tory-fill coolant is 105,000 miles
(168,000 km) or 7 years. Mixing
any other type of coolant other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue), includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green), or
the use of non-distilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
“9. Maintenance and schedules”
section of this manual for more
details.
ENGINE COOLING SYSTEM

JVM0087X
CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is running and after it
reaches normal operating temperature.
If the coolant level is below the MIN level
,
add coolant up to the MAX level. If the
reservoir is empty, check the coolant level
in the radiator when the engine is cold.
If there is insufficient coolant in the
radiator, fill the radiator with coolant up
to the radiator filler cap above the radia-
tor upper hose opening and also add it to
the reservoir up to the MAX level
. Put on
the filler cap above the radiator upper
hose and with the reservoir cap open,
start the engine. Run the engine until it
reaches normal operating temperature. Add coolant up to the MAX level
. Tighten
the cap securely after adding engine
coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom-
mended you visit a NISSAN dealer for
this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling
system repairs be performed by a NISSAN
dealer. The service procedures can be
found in the appropriate NISSAN Service
Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.
WARNING
. To avoid the danger of being
scalded, never change the cool-
ant when the engine is hot.
. Never remove the radiator cap
when the engine is hot. Serious
burns could be caused by high
pressure fluid escaping 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 pos-
sible.
. Keep coolant out of reach of
children and pets.
Engine coolant must be disposed of
properly. Check your local regulations.

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent heavy spark knock even when
using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, it is recommended you have a
NISSAN dealer correct the condition.
Failure to correct the condition is mis-
use of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
have your vehicle checked at a NISSAN
dealer or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time underheavy engine load.
