Cylinder Head Assembly

Cylinder Head Torque





Tighten the new bolts in the sequence shown in the following 5 stages:
Stage 1: Tighten the bolts to 5 Nm {0.50 kgf-m, 44 in-lbf}.
Stage 2: Tighten the bolts to 15 Nm {1.5 kgf-m, 11 ft-lbf}.
Stage 3: Tighten the bolts to 45 Nm {4.5 kgf-m, 33 ft-lbf}.
Stage 4: Turn the bolts 90 degrees.
Stage 5: Turn the bolts an additional 90 degrees.

Bolt Re-usability

NOTE: The cylinder head bolts are torque-to-yield and must not be reused. New cylinder head bolts must be installed.

Camshaft Bearing Cap Torque and Sequence





Install the camshafts and bearing caps in their original location and orientation. Tighten the bolts in the sequence shown in three stages.

Stage 1: Tighten the camshaft bearing cap bolts one turn at a time, until finger tight.
Stage 2: Tighten the bolts to 7 Nm {0.7 kgf-m, 62 in-lbf}.
Stage 3: Tighten the bolts to 16 Nm {1.6 kgf-m, 12 ft-lbf}
