REMOVAL SERVICE POINT

<<A>> CYLINDER HEAD BOLTS REMOVAL

Using special tool cylinder head bolt wrench 
(MB991654), loosen the cylinder head bolts in two or 
three steps in the order of the numbers shown in the 
illustration.

NOTE: 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.

INSTALLATION SERVICE POINTS

>>A<< CYLINDER HEAD GASKET INSTALLATION

CAUTION

Do not allow any foreign materials to get into the 
coolant passages, oil passages and cylinder.

1. Remove the gasket from the cylinder head and 

cylinder block.

2. Assemble to the cylinder block so the cylinder 

head gasket identification mark "63" 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 bolt with a new one.

Limit (A): 99.4 mm

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

the bolts and to the washers.

3. Use special tool cylinder head bolt wrench 

(MB991654) to tighten the cylinder head bolts as 
follows:
(1) Tighten the cylinder head bolts to 78 

–

 2 N

¼

m 

in the order shown.

(2) Loosen the bolts fully in the reverse order of 

that shown.

(3) Tighten the cylinder head bolts to 20 

–

 2 N

¼

m 

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 tightened sufficiently if the bolt is 
tightened less than 90 degree angle.

(5) Tighten the bolt an additional 90 degree angle 

as shown. Then check to see that the paint 
mark on the head of the cylinder head bolts 
and the paint mark on the cylinder head are 
aligned.

(6) If tightening the bolt 90 degree angle results in 

moving the paint mark on the bolt past the 
paint mark on the cylinder head, remove the 
bolt and start over from step 1.

>>C<< O-RING/FUEL HIGH-PRESSURE HOSE 
INSTALLATION

CAUTION

Do not let any engine oil get into the delivery 
pipe.

1. Apply a small amount of new engine oil to the O-

ring.

2. Turning the fuel high-pressure hose to the right 

and left, install it to the delivery pipe, while being 
careful not to damage the O-ring. After installing, 
check that the hose turns smoothly.

3. If the hose does not turn smoothly, the O-ring is 

probably being clamped. Disconnect the fuel high-
pressure hose and check the O-ring for damage. 
After this, re-insert it to the delivery pipe and 
check that the hose turns smoothly.

4. Tighten the fuel high-pressure hose mounting 

bolts to the specified torque.

Tightening torque: 5.0
