1. Undo the two fixing bolts (1) and remove the right head fuel manifold (1b) complete with injectors.
1. Undo the six fixing bolts (1a) and remove the intake manifold (1b) complete with gasket underneath.
1. Open the bands and disconnect the water supply pipe (1a) from the thermostat to the radiator, the water supply pipe (1b) to the heater, the water return pipe (1c) from the heater, the breather pipe (1d) and the fluid feeder pipe (1e) from the pump.2.

1. Undo the bolt (1a) fixing the alternator mounting bracket (1b) to the head
1. Undo the nuts (1a) fixing the right head to the cylinder block/crankcase then, with the help of a second mechanic, remove the head (1b) and the gasket underneath.
1. Position the liner/bore locks (1a) fastening them to the studs (1b).
Refitting ( Removing ) - Remove the liner/bore locks.- Position the cylinder head gasket on the cylinder block/crankcase.
The cylinder head gasket is the Astadur type. The material from which the gasket is made undergoes a polymerization process during the operation of the engine so that it becomes considerably harder during usage. In order for the polymerization process to take place, it is necessary to: - keep the gasket sealed in its container until it is fitted; - not lubricate the gasket or contact surfaces or get oil on them.
Two mechanics are needed for this stage
- Position the cylinder head on the studs.1. Tighten the nuts (1a) fixing the cylinder head to the recommended torque, in stages, using the angular tightening tool (1b).
Follow the order shown in the figure for each tightening sequence.
