ENGINE COOLING SYSTEM  
VQ40DE ENGINE MODEL  
WARNING:  
.
Never remove the radiator or coolant  
reservoir cap when the engine is hot.  
Serious burns could be caused by high-  
pressure fluid escaping from the radiator.  
Wait until the engine and radiator cool  
down.  
.
Engine coolant is poisonous and should  
be stored carefully in marked containers  
out of the reach of children.  
The engine cooling system is filled at the  
factory with a high-quality, year-round, anti-  
freeze coolant solution. The anti-freeze solu-  
tion contains rust and corrosion inhibitors,  
therefore additional cooling system additives  
are not necessary.  
CAUTION:  
.
.
Never use any cooling system additives  
such as radiator sealer. Additives may  
clog the cooling system and cause da-  
mage to the engine, transmission and/or  
cooling system.  
When adding or replacing coolant, be  
sure to use only Genuine NISSAN Engine  
Coolant or equivalent in its quality with  
the proper mixture ratio. Examples of the  
mixture ratio of coolant and water are
