70. INSTALL CYLINDER HEAD SUB±ASSY
HINT:

The cylinder head bolts are tightened in 4 successive
steps (steps (c), (e), (f) and (g)).

If the cylinder head bolt is broken or deformed, replace it
with a new bolt.
(a) Apply a light coat of engine oil on the threads of the cylin-
der head bolts and the plate washers.
(b) Install the plate washer to the cylinder head bolt.
(c) Using several steps, install and tighten the 18 cylinder head bolts uniformly in the sequence shown in the illustra-
tion.
Torque: 45 N

HINT:
See the table below for the bolt length.
Bolt TypeBolt Length
(A)160mm (6.30 in.)
(B)104mm (4.09 in.)
If the cylinder head bolt does not meet the torque specification,
replace the cylinder head bolt with a new bolt.
(d) Mark the front of the cylinder head bolt with paint.
(e) Retighten the cylinder head bolts by 90  in the same se-
quence as step (c).
(f) Retighten the cylinder head bolts by additional 90  in the
same sequence as step (c).
(g) Retighten the cylinder head bolts by one more additional 90 in the same sequence as step (c).
(h) Check that each painted mark is now at the intake man- ifold side.
71. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Using the crankshaft pulley bolt, turn the crankshaft to set the dot mark of the crankshaft timing pulley at the position
of 90  BTDC.
NOTICE:
If the timing belt is disengaged, having the crankshaft tim-
ing pulley at wrong angle can cause the piston head and
valve head to come into contact with each other.
