A" CYLINDER HEAD BOLTS REMOVAL
Use the special tool to loosen the bolt in 2 to 3 times in
the order of the numbers shown in the illustration for removal.
INSTALLATION SERVICE POINTS
"
AA CYLINDER HEAD GASKET INSTALLATION
1. Remove residual gasket attached on the mounting surface
of the gasket.
Caution
Do not let contaminants get into engine coolant, oil
passage or cylinder.
2. With individual holes of cylinder head aligned on individual
holes of cylinder head gasket, install cylinder head gasket
on cylinder head.
"
BA CYLINDER HEAD BOLTS INSTALLATION
1. Ensure that the length under head of cylinder head bolts
is under the limit value. When the measured value exceeds
the limit value, replace the bolt with new one.
Limit (A): 99.4 mm
2. Apply small quantity of engine oil at the threads of cylinder
head bolts and the washers.

3. Use special tool to tighten bolts according to the following
procedure (tightening for plastic zone)
(1) According to the sequence specified in the figure,
tighten the bolt to the specified torque 78 ± 2 N·m.
(2) In the reverse sequence of the figure, fully loosen
bolts.
(3) According to the sequence specified in the figure,
tighten bolts to the specified torque 20 ± 2 N·m.
(4) Indicate paint markings on the heads of cylinder head
bolts and cylinder head, and tighten bolts at the angle
of 90 degree in the sequence specified in the figure.
(5) When bolts are tightened at the angle of 90 degree
according to the figure, ensure that the paint markings
on the heads of cylinder head bolts and cylinder head
are standing in line.
Caution
1) When the tightening angle is under 90 degree,
the bolt is not sufficiently tightened.
2) When the tightening angle exceeds the
specified value, remove the bolt and repeat
the same procedure beginning with Step 1.
"
CA O-RING/FUEL HIGH PRESSURE HOSE
INSTALLATION
1. Apply small quantity of new engine oil on O-ring.
Caution
Do not let engine oil get into the delivery pipe.
2. Install the fuel high pressure pipe to the delivery pipe
rotating in both directions without damaging the O-ring
