    • The cylinder head set bolts are tightened in 3 successive steps.


    1. Place the cylinder head sub-assembly on the cylinder block.

      Note


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

      • Place the cylinder head sub-assembly on the cylinder block gently so as not to damage the gasket with the bottom part of the head.

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

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

    4. A01W9EHN10

      Step 1:

      Using several steps, install and uniformly tighten the 10 cylinder head set bolts with plate washers in the sequence shown in the illustration.

      Torque:
      39 N*m  { 398 kgf*cm, 29 ft.*lbf }

    5. Mark the front of each cylinder head set bolt head with paint.

    6. Step 2:

      Tighten the cylinder head set bolts 90° in the sequence shown in step 1.

    7. Step 3:

      Tighten the cylinder head set bolts another 90° in the sequence shown in step 1.

    8. Check that the paint marks are now at a 180° angle to the front.

  3. CONNECT ENGINE WIRE


    1. A01W8JEC01
      *a INCORRECT
      *b Do not Allow Wires to Overlap

      Connect the engine wire to the cylinder head sub-assembly with the 3 bolts so that it is within the specified range shown in the illustration.

      Torque:
