Cylinder head, removing and installing: Installing
WARNING: This page is about a different variant/trim than selected.
NOTE:
- There must be no oil or coolant in the blind holes for the cylinder head bolts in the cylinder block.
- Only remove the new cylinder head gasket from its packing immediately before installing.
- Handle the new gasket with extreme care. Damaging will lead to leaks.
- Stuff clean cloths into cylinder so that no dirt or abrasive powder can get between cylinder wall and piston.
- Do not allow dirt or abrasive powder to get into coolant either.
- Carefully clean cylinder head and cylinder block sealing surfaces. Avoid introducing scratches or scoring (do not use sandpaper with grit below 100).
- Carefully remove metal particles, emery remains and cloths.
- Turn crankshaft to set cylinder 1 at TDC.
- Turn crankshaft back slightly.
- To center, install Guide Pins 3070 in cylinder head bolts 8 and 10.
- Install new cylinder head gasket. Text (replacement part number) must be visible.
- Install cylinder head, insert remaining 8 cylinder head bolts and hand tighten.
- Remove Guide Pins 3070 through bolt holes with guide pin handle. Do this by turning pin handle toward left until pins are free.
- Insert both remaining cylinder head bolts and then fasten them hand-tight.
- Tighten cylinder head in tightening sequence as follows:
- Pre-tighten all bolts to 40 Nm.
- Then tighten all bolts a 1 / 4 turn (90 ° ) further using a rigid wrench.
- Then tighten all bolts again a 1 / 4 turn (90 ° ) further.
The rest of the assembly is basically a reverse of disassembling sequence.
