Cylinder Head Bolt Torque/Sequence
Apply a coat of engine oil to washers and bolt threads.
Then tighten all bolts to 69 N.m (7.0 kg-m, 51 ft-lb) in numerical order.
Back off all bolts by 180° first; back them off by 180° again.
Re-tighten bolts (1) and (2) to 36.8 N.m (3.75 kg-m, 27.1 ft-lb).
Re-tighten bolts (3), (4), (5) and (6) to 20 N.m (2.0 kg-m, 14 ft-lb) .
Tighten all bolts by 80° to 90° in numerical sequence.
CAUTION: Do not tighten bolts more than 90° .
Further tighten all bolts by 80° to 90° in numerical sequence.
CAUTION: Ensure that the total "re-tightening angle" does not exceed 180° .
