RECOMMENDED FLUIDS AND LUBRICANTS
Engine Coolant Mixture Ratio
ELS000AN
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 necessary.
CAUTION:
●When adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant (L2N) or equivalent.
Because L2N is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.
●When checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant
temperature.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.
