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.
