PRECAUTIONS
Parts Requiring Angular Tightening
Parts Requiring Angular Tightening
I
Some important engine parts are tightened using an angular-
tightening method rather than a torque setting method.
I
If these parts are tightened using a torque setting method,
dispersal of the tightening force (axial bolt force) will be two or
three times that of the dispersal produced by using the correct
angular-tightening method.
I
Although the torque setting values (described in this manual)
are equivalent to those used when bolts and nuts are tightened
with an angular-tightening method, they should be used for
reference only.
I
To assure the satisfactory maintenance of the engine, bolts
and nuts must be tightened using an angular-tightening
method.
I
Before tightening the bolts and nuts, ensure that the thread
and seating surfaces are clean and then coated with engine oil.
I
The bolts and nuts which require the angular-tightening
method are as follows:
(1) Cylinder head bolts ..... SR, CD, QG
(2) Main bearing cap bolts ..... SR
(3) Connecting rod cap nuts ..... SR, QG

Liquid Gasket Application Procedure
a. Before applying liquid gasket, use a scraper to remove
all traces of old liquid gasket from mating surface and
groove, and then completely clean any oil stains from
these areas.
b. Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
I
Be sure liquid gasket is 4.0 to 5.0 mm (0.157 to 0.197
in) wide for SR engine and 3.5 to 4.5 mm (0.138 to
0.177 in) wide for QG and CD engine (for oil pan).
Groove
Bolt hole
Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to
0.118 in) wide (in areas except oil pan).
c. Apply liquid gasket to inner surface around hole perim-
eter area.
(Assembly should be done within 5 minutes after coat-
ing.)
d. Wait at least 30 minutes before refilling with engine oil
and engine coolant.
