Hi,

 

Below is tightening torques and sequence:

 

  • Using the cylinder head alignment pins, position the cylinder head gasket and cylinder head onto the dowels and install the cylinder head bolts loosely.
  • Tighten the bolts in the sequence shown.
    1. Stage 1: Tighten to 40 Nm (30 ft. lbs.).
    2. Stage 2: Tighten an additional 90 degrees.
    3. Stage 3: Tighten an additional 90 degrees.
