<<D>> CYLINDER HEAD BOLTS REMOVAL
Use special tool MB991654 to loosen the cylinder head bolts in
two or three steps in the order of the numbers shown in the
illustration. If the cylinder head bolts cannot be pulled out due
to the washer being trapped in the valve spring, raise the bolt
slightly, then remove it while holding it by using a magnet.

>>A<< CYLINDER HEAD GASKET INSTALLATION

CAUTION

Do not allow any foreign materials get into the coolant pas-
sages, oil passages and cylinder.
1. Degrease the cylinder head gasket mounting surface.
2. Assemble to the cylinder block so the cylinder head gasket

identification mark of "381" is at the top surface and on the
exhaust side.

.

>>B<< CYLINDER HEAD BOLTS INSTALLATION
1. Check that the nominal length of each cylinder head bolt

meets the limit. If it exceeds the limit, replace the bolts with a
new one.

Limit (A): 99.4 mm (3.91 inches)

2. Apply a small amount of engine oil to the thread of the bolts

3. Use special tool MB991654 to tighten the cylinder head

bolts in the following procedures.

(1) Tighten the bolts to 78

± 2 N⋅m (58 ± 1 ft-lb) in the order

shown.

(2) Loosen the bolts fully in the reverse sequence to that

shown.

(3) Tighten the bolts to 20

± 2 N⋅m (15 ± 1 ft-lb) in the order

shown.

(4) Apply a paint mark to the heads of the cylinder head bolts

and cylinder head, then tighten 90 degree angle as
shown.

CAUTION

• The bolt is not tightening sufficiently if the tightening

angle is less than a 90 degree angle.

• If the tightening angle exceeds the standard specifica-

tion, remove the bolt and start over from step 1.

(5) Tighten in a 90 degree angle as shown in the instructions

of the figure, then check to see that the paint mark on the
head of the cylinder head bolts and the paint mark on the
cylinder head is on a linear line.
