NOTE:
(1) First replace at 90,000 km (54,000 miles), then every 60,000 km (36,000 miles). Perform ªIº (checking the mixture ratio and
correcting the mixture ratio if necessary) at the middle of replacement interval.
(2) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
(3) Fuel filter is maintenance-free. For service procedures, refer to FE section.
(4) Perform only according to ªMaintenance Under Severe Driving Conditionsº for models without Euro-OBD system. For
models with Euro-OBD system, periodic maintenance is not required.
HMaintenance items with ªHº should be performed more frequently according to ªMaintenance Under Severe Driving Con-
ditionsº.

SMA089D
Engine Coolant Mixture Ratio=NJMA0006S03The 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 cool-
ing system additives are not necessary.
CAUTION:
+For Europe
When adding or replacing coolant, be sure to use only
Genuine NISSAN Anti-freeze Coolant (L2N) or equivalent.
Because L2N is premixed type coolant.
+Except for Europe
When adding or replacing coolant, be sure to use only a
Nissan Genuine Engine Coolant or equivalent in its qual-
ity with the proper mixture ratio. See the examples shown
left.
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.

WARNING:
Never remove the radiator 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.

Parts Requiring Angular TighteningNJEM0001+Use an angle wrench for the final tightening of the following
engine parts:
a) Cylinder head bolts
b) Main bearing cap bolts
c) Connecting rod cap nuts
+Do not use a torque value for final tightening.
+The torque value for these parts are for a preliminary step.
+Ensure thread and seat surfaces are clean and coated with
engine oil.

Liquid Gasket Application ProcedureNJEM00021.Use a scraper to remove old liquid gasket from mating
surfaces and grooves. Also, completely clean any oil from
these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
+For areas except oil pan, be sure liquid gasket diameter is
2.0 to 3.0 mm (0.079 to 0.118 in).
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.
