Installation procedure
Cylinder bank 1
1. Installation should be carried out in the reverse order of removal of parts.
2. Using the EN-46111 tool (1) for turning the crankshaft, align the timing mark (2) on the crankshaft sprocket with the mark (3) on the oil pump housing.
3. Ensure that the surface of the block-cylinder head joint is clean and that the pins for installing the head are securely fastened to it.
4. Install a new cylinder head gasket (1), using the dowel pins on the mating surface to secure it.
5. Correctly position the cylinder head relative to the dowel pins.
6. Install the cylinder head into place.
Note: It is necessary that there is no oil on the bolt bosses on the cylinder head.
Caution: Cylinder head bolts must not be reused (from 1st to 8th inclusive).
7. Install a new cylinder head bolt (1) (eight seats) and tighten in the sequence shown.
Tighten
Tighten the cylinder head bolts to 45 N·m (33 lb-ft) and turn the bolts an additional 120° using the angular torque gauge KM-470-B.
8. Install all previously removed external parts.

Tighten
Tighten the front cylinder head bolts to 15 N·m (11 lb-ft) and turn each bolt an additional 60° using the angular torque gauge KM-470-B.
9. Install all previously removed external parts.
