NOTE:Cylinder head bolts are a torque-to-yield design. New bolts must be installed.Install the eight 12 mm (0.47 in) bolts and tighten in the sequence shown in two stages.
- Stage 1: 12 Nm {1.2 kgf-m, 9 ft-lbf}
- Stage 2: 25 Nm {2.5 kgf-m, 18 ft-lbf}
1. Install the two 8 mm (0.31 in) bolts.
1. Tighten the eight 12 mm (0.47 in) bolts in two stages in the sequence shown.
- Stage 1: Tighten the bolts 90 degrees.
- Stage 2: Tighten the bolts an additional 90 degrees.
1. Position the LH camshaft sprocket in the chain and install it on the camshaft.
1.
CAUTION:The camshaft sprocket must turn freely on the camshaft. DO NOT tighten the bolt.Install the camshaft sprocket bolt.
