Tightening Specifications

Cylinder Head Tightening Torque and Sequence





- Tighten cylinder head in following four stage sequence:
1. Tighten initially using torque wrench:
Stage I = 40 Nm (30 ft. lbs.)
Stage II = 60 Nm (44 ft. lbs.)
2. Turn further with a normal wrench:
Stage III = 1/4 turn (90°)
Stage IV = 1/4 turn (90°)

NOTE: Loosen cylinder head bolts in reverse of tightening sequence shown above.
