cylinder block and on the bottom surface of the cylinder 
head. Then, use the white gasoline or the like to degrease 
the sealant application surface.

2. Apply the sealant to the top surface of cylinder block as 

shown in the figure.

Specified sealant: ThreeBond 1217G or equivalent

NOTE: Install the cylinder head gasket immediately after 
applying sealant.

3. Install the cylinder head gasket to the cylinder block.

NOTE: When the cylinder head gasket is installed to the cyl-
inder block, check that the sealant is securely applied to the 
bead line of the cylinder head gasket.

4. Apply the sealant to the top surface of cylinder head gasket 

as shown in the figure.

Specified sealant: ThreeBond 1217G or equivalent

NOTE: Install the cylinder head assembly immediately after 
applying sealant.

CAUTION

After the installation, until a sufficient period of time (one 
hour or more) elapses, do not apply the oil or water to the 
sealant application area or start the engine.

the order of number shown in the figure.

Tightening torque: 35 

± 2 N⋅m (26 ± 1 ft-lb)

CAUTION

• When the tightening angle is smaller than the specified 

tightening angle, the appropriate tightening capacity 
cannot be secured.

• When the tightening angle is larger than the specified 

tightening angle, remove the cylinder head bolt to start 
from the beginning again according to the procedure.

(2) Apply paint marks to the head of cylinder head bolt and
