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

4. Set the crankshaft to top dead center (TDC). Align
the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
5. Set the camshaft pulley to TDC (see step 2 on page 6-21).
6. Install the cylinder head on the engine block.
7. Measure the diameter of each cylinder head bolt at point A and point B.
8. If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt. 9. Apply new engine oil to the threads and under the
bolt heads of all cylinder head bolts.
10. Tighten the cylinder head bolts in sequence to 39 N·m (4.0 kgf·m, 29 lbf·ft). Use a beam-type
torque wrench. When using a preset click-type
torque wrench, be sure to tighten slowly and do not
overtighten. If a bolt makes any noise while you are
torquing it, loosen the bolt and retighten it from the
first step.
11. After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown in
step 10. If you are using a new cylinder head bolt,
tighten the bolt an extra 90 °.
NOTE: Remove the cylinder head bolt if you
tightened it beyond the specified angle, and go
back to step 6 of the procedure. Do not loosen it
back to the specified angle.

19. Connect the positive crankcase ventilation (PCV)hose (A) (K20Z2 engine) and install the ground
cable (B).
20. Connect the fuel feed hose (A) (see page 11-331), then install the quick-connect fitting cover (B). 21. Connect the evaporative emission (EVAP) canister
hose (A) and the brake booster vacuum hose (B).
22. Install the exhaust manifold (see page 9-11).
23. Install the intake manifold: K20Z2 engine (see page 9-4)
K20Z3 engine (see page 9-9)
24. Install the drive belt (see page 4-31).
25. Install the air cleaner assembly (see page 11-345).
26. After installation, check that all tubes, hoses and connectors are installed correctly.
27. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so that 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.
