  1. INSTALL CYLINDER HEAD SUB-ASSEMBLY LH

    1. Clean the threads of the cylinder head bolts and apply sufficient engine oil to the washers and threads of the bolts.

    2. Mount the cylinder head sub-assembly LH on the cylinder block (bank 2).

      Tighten the 6 cylinder head bolts in the order shown in the illustration.

      100 N*m

      1020 kgf*cm

      Note:

      If the bolt makes a stick-slip sound during tightening, repeat the procedure from the cylinder head gasket installation after cleaning and completely drying the bolt holes and contact surfaces.

      In that case, the No. 2 cylinder head gasket can be reused.
