Parts Requiring Angular Tightening
lUse an angle wrench for the final tightening of the following
engine parts:
(1) Cylinder head bolts
(2) Connecting rod cap nuts
lDo not use a torque value for final tightening.
lThe torque values for these parts are for a preliminary step.
lEnsure thread and seat surfaces are clean and coated with
engine oil.
Liquid Gasket Application Procedure
a. Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely
clean any oil from these areas.
b. Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
lFor oil pan, be sure liquid gasket diameter is 3.5 to 4.5
mm (0.138 to 0.177 in).
lFor areas except oil pan, be sure liquid gasket diam-
eter is 2.0 to 3.0 mm (0.079 to 0.118 in).
c. Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
d. Assembly should be done within 5 minutes after coating.
e. Wait at least 30 minutes before refilling engine oil and
engine coolant.
