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.

Removal and InstallationNJEM0024CAUTION:
+When installing sliding parts such as bearings and
pistons, apply engine oil on the sliding surfaces.
+Place removed parts, such as bearings and bearing caps,
in their proper order and direction.
+When installing connecting rod nuts and main bearing cap
bolts, apply new engine oil to threads and seating sur-
faces.
+Do not allow any magnetic materials to contact the signal
plate teeth of flywheel or drive plate, and rear plate.
+Remove the crankshaft position sensor (POS).
+Be careful not to damage sensor edges and single plate
teeth.

2. Drain coolant and oil.
3. Remove timing chain.
Refer to EM-23.

4. Remove pistons with connecting rod.
+When disassembling piston and connecting rod, remove snap
ring first. Then heat piston to 60 to 70ÉC (140 to 158ÉF) or use
piston pin press stand at room temperature.
CAUTION:
+When piston rings are not replaced, make sure that piston
rings are mounted in their original positions.
+When replacing piston rings, if there is no punch mark,
install with either side up.

5. Loosen main bearing caps in numerical order as shown in fig-
ure.
6. Remove bearing caps, main bearings and crankshaft.
+Before removing bearing caps, measure crankshaft end
play. Refer to EM-61.
+Bolts should be loosened in two or three steps.
