Continuation for both sides: |
–
| Slacken cylinder head bolts in the sequence -1 ... 8-. |
–
| Remove bolts and carefully take off cylinder head. |
Caution Risk of damage to glow plugs when putting down cylinder head. |
After removal, the cylinder head must not be put down on the gasket side with the glow plugs still installed, because the glow plugs project slightly beyond the gasket surface. |
|
Installation is carried out in the reverse order; note the following: |
Caution Avoid damage to sealing surfaces. |
t
| Carefully remove sealant residue from cylinder head and cylinder block. |
t
| Ensure that no long scores or scratches are made on the surfaces. |
Avoid damage to cylinder block. |
No oil or coolant must be allowed to remain in the blind holes for the cylinder head bolts in the cylinder block. |
Risk of leaks at cylinder head gasket. |
t
| Carefully remove any remaining emery and abrasive material. |
t
| Do not remove new cylinder head gasket from packaging until it is ready to be fitted. |
t
| Handle the cylinder head gasket very carefully to prevent damage to the silicone coating or the indented area of the gasket. |
Avoid damage to open valves. |
When installing an exchange cylinder head, the plastic protectors fitted to protect the open valves should not be removed until the cylinder head is ready to be fitted. |
Avoid damage to valves and piston crowns after working on valve gear. |
Turn the engine carefully at least 2 rotations to ensure that none of the valves make contact when the starter is operated. |
|
Note t
| Renew the bolts tightened with specified tightening angle. |
t
| Renew self-locking nuts as well as seals, gaskets and O-rings. |
t
| Cylinder heads must not be reworked on TDI engines. |
t
| When installing an exchange cylinder head, the contact surfaces between roller rocker fingers and cams must be oiled before installing the cylinder head cover. |
t
| After fitting a new cylinder head or cylinder head gasket, change the engine oil and the coolant in the entire cooling system. |
