Installation procedure
Bank 1
1. Installation is carried out in the reverse order to the removal of parts.
2. Using the EN-46111 fixture (1) to rotate the crankshaft, align the alignment mark (2) on the crankshaft sprocket with a mark (3) on the oil pump housing.
3. Ensure that the joint surface of the block with the cylinder head is clean and that the pins for installing the head are securely fixed on it.
4. Install new gasket (1) cylinder heads, using the dowel pins on the mating surface to secure it.
5. Correctly position the cylinder head in relation to the dowel pins.
6. Install the cylinder head in place.
Note: The cylinder head bolt bosses must be free of oil.
Attention! Do not reuse cylinder head bolts (from 1st to 8th inclusive).
7. Install new bolt (1) cylinder heads (eight seats) and tighten in sequence.
Tighten
Tighten cylinder head bolts to 45 Nm (33 lb-ft) and turn the bolts another 120°using the angle torque indicator KM-470-B.
8. Install all previously removed external parts.
