6. Make sure the punch marks on the variable valve timing control (VTC) actuator and the exhaust
camshaft sprocket are facing up, then set the
camshafts (A) in the holder. Apply new engine oil to
the camshaft journals and lobes.
7. Set the camshaft holders (C) and cam chain guide B in place.
8. Tighten the bolts in sequence to the specified torque.
NOTE: If the engine does not have bolt , skip it
and continue the torque sequence.
9. Install the cam chain (see page 6-21), then adjust the valve clearance (see page 6-14). 1. Install a new coolant separator (A) in the engine
block whenever the engine block is replaced.
2. Clean the cylinder head and the engine block surface.
3. Install the new cylinder head gasket (A) and the dowel pins (B) on the engine block. Always use a

13. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation three times, then check
for fuel leakage at any point in the fuel line.
14. Clean up any spilled engine coolant.
15. After installation, check that all tubes, hoses and connectors are installed correctly.
