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.

parts, lubricate contacting surfaces with new engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.
+When removing oil pump assembly, remove camshaft
position sensor (PHASE), then remove timing chain from
engine.
+Be careful not to damage sensor edges.

WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Before disconnecting fuel hose, release pressure.
Refer to EC-40, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
safe manner.
+When removing drive shaft, be careful not to damage
grease seal of transaxle.
+Before separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
+Always be extra careful not to damage edge of crankshaft
position sensor (POS), or signal plate teeth.
Engine cannot be removed separately from transaxle. Remove
engine with transaxle as an assembly.
REMOVALNJEM0022S011. Drain coolant from radiator and cylinder block. Refer to LC-18,
ªChanging Engine Coolantº.
2. Remove coolant reservoir tank and bracket.

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.

+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.
