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).

   3. 

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

      15 ft.*lbf

   4. Tighten the 6 cylinder head bolts further in the same order above.

      100 N*m

      1020 kgf*cm

      74 ft.*lbf

      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.

      Tip

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

   5. 

      Loosen the 6 cylinder head bolts by 360 ° in the order shown in the illustration.
