Parts Requiring Angular TighteningNJEM0047+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
d) Crankshaft pulley bolt
+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.
SEM164F
Liquid Gasket Application ProcedureNJEM00481.Use a scraper to remove all traces of 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.)
+Be sure liquid gasket diameter is as specified.
AEM080
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.

13. For Europe only, remove catalyst rear diffuser, EM-109, ªCata-
lyst (For Europe)º.
14. Remove upper oil pan bolts in reverse order.
15. Remove four engine-to-transaxle bolts using a universal
socket. (Commercial Service Tool).
16. Remove upper oil pan.
a. Insert an appropriate size tool into the notch of upper oil pan.
+Be careful not to damage aluminum mating surface.
+Do not insert screwdriver, or oil pan flange will be
deformed.
b. Pry off upper oil pan by moving the tool up and down.
c. Remove upper oil pan.
+Be careful to prevent No. 15 and 16 blots from falling into
transaxle case.
JEM117G
InstallationNJEM00561. Install upper oil pan.
a. Use a scraper to remove old liquid gasket from mating sur-
faces.
+Also remove old liquid gasket from mating surface of cyl-
inder block, front cover and lower oil pan.
+Remove old liquid gasket from the bolt hole and thread.
SEM159F
b. Apply a continuous bead of liquid gasket to mating surface of
aluminum oil pan.
+Use Genuine Liquid Gasket or equivalent.
JEM118G
c. Apply Genuine Liquid Gasket or equivalent, to areas shown in
the figure.
+At the 8 bolt holes markedH, liquid gasket should be
applied on the rims of the holes.
+Be sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in)
or 4.5 to 5.5 mm (0.177 to 0.217 in) wide. (Be careful that
the diameter of the silicon bead is different around the
front.)
+Attaching should be done within 5 minutes after coating.
