Maintenance and do-it-yourself -> Engine cooling system for Your Nissan Juke SUV 2020

ENGINE COMPARTMENT  
ENGINE COOLING SYSTEM  
Never connect or disconnect either the bat-  
tery or any transistorised component connec-  
tor while the ignition switch is in the ON posi-  
tion.  
For an overview of the engine compartment, see  
“Engine compartment” in the “0. Illustrated table  
of contents” section.  
WARNING  
Never remove the engine coolant reservoir  
cap when the engine is hot. Serious burns  
could be caused by high pressure fluid escap-  
ing from the engine coolant reservoir. Wait un-  
til the engine and radiator have cooled down.  
Never leave the engine or transmission related  
component harness connector disconnected  
while the ignition switch is in the ON position.  
Engine coolant is poisonous and should be  
stored carefully in marked containers out of  
the reach of children.  
On petrol engine models with the multiport  
fuel injection (MFI) system, the fuel filter or fuel  
lines should be serviced by a NISSAN dealer or  
qualified workshop because the fuel lines are  
under high pressure even when the engine is  
off.  
The engine cooling system is filled at the factory  
with a high-quality, year-round and extended life  
engine coolant. The high quality engine coolant  
contains the specific solutions effective for the anti-  
corrosion and the anti-freeze function. Therefore,  
additional cooling system additives are not neces-  
sary.  
Always wear eye protection whenever you  
work on your vehicle.

damage.  
Improperly disposed engine oil and/or other  
vehicle fluids can pollute the environment. Al-  
ways conform to local regulations for disposal  
of vehicle fluid.  
This section gives instructions regarding only those  
items which are relatively easy for an owner to per-  
form.  
You should be aware that incomplete or improper  
servicing may result in operating difficulties or ex-  
cessive emissions, and could affect your warranty  
coverage. If in doubt about any servicing, have it  
done by your NISSAN dealer or qualified work-  
shop.

CAUTION  
Major cooling system repairs should be performed  
by a NISSAN dealer or qualified workshop. The ser-  
vice procedures can be found in the appropriate  
NISSAN Service Manual.  
Never use any cooling system additives such  
as radiator sealer. Additives may clog the cool-  
ing system and cause damage to the engine,  
transmission and/or cooling system.  
When checking or replacement is required, NISSAN  
recommends contacting a NISSAN dealer or quali-  
fied workshop for servicing.  
The engine coolant reservoir is equipped with  
a pressure cap.To prevent engine damage,use  
only a Genuine NISSAN cap or its equivalent  
when replacement is required.  
Improper servicing or engine coolant change can  
result in reduced heater performance and engine  
overheating.  
When adding or replacing engine coolant, be  
sure to use Genuine NISSAN engine coolant or  
equivalent in its quality with the proper mix-  
ture ratio. The use of other types of coolant  
solutions may damage the engine cooling  
system.
