(1) Apply a thin coat of engine oil to washers and cylinder head bolt threads. (2) Mount the cylinder head onto the cylinder block, then tighten the bolts with a torque of 20 N·m (2.0 kgf-m, 14.8 ft-lb) in the order indicated in the figure. (3) Tighten the bolts with a torque of 50 N·m (5.1 kgf-m, 36.9 ft-lb) in the order indicated in the figure. (4) Loosen all the bolts by 180° in the reverse order of installing, and loosen them further by 180°. (5) Tighten the bolts with torque of 20 N·m (2.0 kgf-m, 14.8 ft-lb) in numerical sequence as shown in the figure. (6) Tighten the bolts (1) — (4) in the order indicated with a torque of 48 N·m (4.9 kgf-m, 35.4 ft-lb). (7) Tighten the bolts (5) — (8) in the order indicated with a torque of 44 N·m (4.5 kgf-m, 32.5 ft-lb). (8) Tighten all bolts 90° in the numerical order as shown in the figure. (9) Tighten the bolt (1) — (4) by 45° in the numerical order.
