CAUTION:

The sealing surfaces could be damaged.

Carefully remove sealant residue from cylinder head and cylinder block.
Make sure that no long scrapes or scratches result.

Risk of damaging cylinder block.

There must be no oil or coolant in the blind holes for the cylinder head bolts in the cylinder block.

Risk of cylinder head seal leaking.

Carefully remove all grinding and sanding residue.
Only unpack new cylinder head gasket immediately prior to installation.
To prevent cylinder head seal silicone layer and recessed area from being damaged, always handle seal extremely carefully.

Risk of damaging open valves.

If a replacement cylinder is installed, only remove plastic base right before cylinder head is installed to protect open valves.

Risk of damaging valves and piston heads after working on valve train.

To ensure valves do not strike pistons when starting, carefully rotate engine at least two full revolutions.

NOTE:

Replace the bolts which are being tightened with an additional turn.

Replace self-locking nuts, sealing rings, seals and O-rings.

If a replacement cylinder is installed, the contact surfaces between the hydraulic adjusting elements, roller rocker levers and cam running surfaces must be lubricated before installing the camshaft housing.

The hose supports, air guide pipes and hoses must be free of oil and grease before installing.

Secure all hose connections with hose clamps of the same type as those equipped by the factory. Refer to the parts information.

To mount the charge hoses on their connectors securely, spray the bolts on the used clamps with rust remover before installing.

It is necessary to replace all the coolant and engine oil whenever the cylinder head or the cylinder head gasket are replaced.
