Fitting cylinder head

3. Thoroughly clean gasket mating surfaces on engine block and cylinder head; then position gasket on engine block with the wording "ALTO" facing the operator.

NOTE The cylinder head gasket is ASTADUR type. This gasket is made out of special material which undergoes a process of polymerisation while the engine is running and thus hardens considerably during use.

Observe the following precautions to ensure gasket polymerisation takes place:

• keep the gasket sealed in its original plastic packet;
• take out of packet shortly before fitting;
• do not lubricate the gasket or contaminate with oil. Take care that cylinder head and engine block surfaces are thoroughly clean.

4. Cylinder head bolt tightening order.
