18) Remove the exhaust camshaft cap and cam-
shaft.
NOTE:
Arrange the camshaft caps in order so that they
can be installed in their original positions.
19) Similarly, remove the camshafts (RH) and re-
lated parts.B: INSTALLATION
1) Camshaft installation: Apply engine oil to cylin-
der head at camshaft bearing location before in-
stalling the camshaft. Install the camshaft so that
each valve is close to or in contact with “base circle”
of cam lobe.
NOTE:
When the camshafts are positioned as shown in
the figure, camshafts need to be rotated at a mini-
mum to align with the timing belt during installation.
Camshaft (RH) need not be rotated when set at
position shown in the figure. Intake camshaft (LH):
Rotate 80° clockwise. Exhaust camshaft (LH): Ro-
tate 45° counterclockwise.
2) Camshaft cap and oil flow control solenoid valve
assembly installation:
(1) Apply liquid gasket sparingly to cap mating
surface.
NOTE:
Do not apply liquid gasket excessively. Failure to
do so may cause excess packing to come out and
flow toward the oil seal, resulting in oil leaks.

9) Remove the cylinder head bolts in alphabetical
sequence shown in the figure.
Leave bolts (A) and (D) engaged by three or four
threads to prevent the cylinder head from falling.
10) While tapping the cylinder head with a plastic
hammer, separate it from cylinder block. Remove
the bolts (A) and (D) to remove cylinder head.11) Remove the cylinder head gasket.
NOTE:
Do not scratch the mating surface of cylinder head
and cylinder block.
12) Similarly, remove the cylinder head (RH).
B: INSTALLATION
1) Install the cylinder head and gaskets on cylinder
block.
NOTE:
Use new cylinder head gaskets.
Be careful not to scratch the mating surface of
cylinder head and cylinder block.
2) Tighten the cylinder head bolts.
(1) Apply a coat of engine oil to the washers and
bolt threads.
(2) Tighten all bolts to 29 N⋅m (3.0 kgf-m, 22 ft-
lb) in alphabetical sequence.
(3) Tighten all bolts to 69 N⋅m (7.0 kgf-m, 51 ft-
lb) in alphabetical sequence again.
(4) Back off all bolts by 180° first; back them off
by 180° again in reverse order of installation.
(5) Tighten all bolts to 49 N⋅m (5.0 kgf-m, 36 ft-
lb) in alphabetical sequence.
(6) Tighten all bolts 80 to 90° in alphabetical se-
quence.
(7) Tighten all bolts by 40 to 45° in alphabetical
sequence again.
NOTE:
Do not tighten the bolts by more than 45°.
(8) Further tighten all bolts (A) and (B) by 40 to
45°.
NOTE:
Ensure that the total “re-tightening angle” in the
previous two steps do not exceed 90°.
3) Install the camshaft.
4) Install the A/C compressor bracket on cylinder
head.
5) Install the intake manifold.
