    Tech Tips

    The cylinder head bolts are tightened in 3 progressive steps.


    1. Place the cylinder head on the cylinder block.

      Note


      • Make sure that no oil is on the mounting surface of the cylinder head.

      • Place the cylinder head on the cylinder block gently in order not to damage the gasket with the bottom part of the head.

    2. Install the plate washers to the cylinder head bolts.

    3. Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.
