7) Loosen cylinder head bolts (M10) in such order as
numbered in figure and remove them.
NOTE
Don’t forget to remove cylinder head bolt
(M6) (3) as shown in figure.
8) Check all around cylinder head for any other parts
required to be removed or disconnected and remove
or disconnect whatever necessary.
9) Remove cylinder head with intake manifold, exhaust

Installation
1) Match match mark (1) on crank timing sprocket and
mating surface (2) of cylinder block and lower
crankcase.
2) Clean mating surface of cylinder head and cylinder
block (2). Remove oil, old gasket and dust from
mating surface.
3) Install knock pins (3) to cylinder block.
4) Install new cylinder head gasket (1) to cylinder block.
Identification number (6) provided on gasket comes

cylinder head side).
5) Install cylinder head to cylinder block.
Apply engine oil to cylinder head bolts and tighten
them gradually as follows.
a) Tighten cylinder head bolts (M10) to 52 N
⋅
m (5.2
kgf-m, 38.0 lb-ft) according to numerical order in
figure.
b) In the same manner as in step a), retighten
cylinder head bolts (M10) to 82 N
⋅
m (8.2 kgf-m,
