1. Undo the bolts (1a) and remove the cylinder head (1b).2. Remove the cylinder head gasket.

Refitting ( Removing

) Fit a new cylinder head gasket.

ASTADUR type cylinder head gaskets are fitted.The material from which these gaskets are made undergoes a polymerization process during the operation of the engine so that they become considerably harder during usage.In order for the polymerization of the gasket to take place it is necessary to:keep the gasket in its sealed container until fittingnot lubricate or get oil on the gasket and the contact surfaces.

Position the cylinder head on the cylinder block, taking care that the camshafts are positioned with the front cams facing outwards (valves closed).1. Tighten the bolts (1a) fixing the cylinder head to the recommended torque using the angular tightening tool (1b).

Follow the order shown in the diagram for each tightening sequence.
