8 6 131-0420 Cylinder Head Fastener Gp Use the following procedure in order to tighten the bolts for the cylinder head:
Refer to Illustration 2 for cylinder head bolt tightening sequence.
1. Before assembly, apply clean engine oil to the threads of the bolts.
2. Tighten bolt 1 through bolt 8 in the numerical sequence to a torque of 30 5 N m (22 4 lb ft).
3. Again, tighten bolt 1 through bolt 8 in the numerical sequence to a torque of 100 15 N m (74 11 lb ft).
4. Again, tighten bolt 1 through bolt 8 in the numerical sequence to a torque of 450 15 N m (332 11 lb ft).
5. Loosen bolt 1 through bolt 8 in the numerical sequence for an angle of 90 5 degrees.
6. Again, tighten bolt 1 through bolt 8 in the numerical sequence to a torque of 490 15 N m (361 11 lb ft).
7. Tighten two bolts (10) only after bolt 1 through bolt 8 have been given the final torque.
8. Tighten two bolts (10) to 55 10 N m (41 7 lb ft).
