Illustration 1 g01417896Note: The top face of the gasket and the top face of the cylinder block, cylinder liners and the bottom face of the gasket and the bottom face of the cylinder head must be free of oil, fuel, water and other contaminants before assembly.Note: Use clean engine oil to lubricate the threads of the cylinder head bolts before assembly.Use the following procedure to tighten the cylinder head bolts:
Torque the bolt (1) through bolt (26) in a numerical sequence to 130 15 N m (95 11 lb ft).
Again torque the bolt (1) through bolt (26) in a numerical sequence to 130 15 N m (95 11 lb ft).
Place a mark on bolt (1) through bolt (26). Rotate the bolt (1) through bolt (26) in the clockwise direction in a numerical sequence to 90 degrees (1/4 turn).
Loosen the bolt (1) through bolt (26) in a numerical sequence to 0 N m (0 lb ft).
Repeat Step 1 through Step 3.
Torque the bolt (27) through bolt (31) in a numerical sequence to 28 7 N m (21 5 lb ft).
