CAUTION

Be careful not to damage or deform the plug guides when
removing the cylinder head bolts. Plug guides cannot be
replaced separately.
Using special tool MB991654, loosen the bolts in two or three
steps in the order of the numbers shown in the illustration, then
remove the cylinder head assembly.

INSTALLATION SERVICE POINTS

>>A<< CYLINDER HEAD GASKET INSTALLATION
1. Wipe off all oil and grease from the gasket mounting

surface.

2. Match the shapes of the cylinder head holes with their

respective cylinder head gasket holes.

>>B<< CYLINDER HEAD ASSEMBLY INSTALLATION
1. When installing the cylinder head bolts, the length below the

head of the bolts should be within the limit.

CAUTION

•

Always tighten cylinder head bolts at a 90 degree angle.
If it is less than 90 degree angle, the bolt will loosen.

•

If it is more than 90 degree angle, remove the head bolt
and repeat the procedure from step 1.

3. Using special tool MB991654, tighten the bolts by the

following procedure.

>>C<< HIGH-PRESSURE FUEL HOSE INSTALLATION

CAUTION

Do not allow engine oil to enter the fuel rail.
1. Apply a small amount of new engine oil to the O-ring.

2. While turning the high-pressure fuel hose to the right and

left, install the fuel rail, 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 high-pressure fuel hose and
check the O-ring for damage.

4. Re-insert the fuel rail and confirm the hose turns smoothly.
