13. Install the rocker arm assembly (see step 10 on «CAMSHAFT, ROCKER ARM ASSEMBLY, CAMSHAFT SEAL, AND PULLEY INSTALLATION»(ref-333551-S20923989242009072100000) ), then tighten the mounting bolts.
14. Install the timing belt (see «TIMING BELT INSTALLATION»(ref-333551-S12213281632009072100000) ).
15. Adjust the valve clearance (see «VALVE CLEARANCE ADJUSTMENT»(ref-333551-S26574303442009072100000) ).
16. Install the heater hoses and the purge joint bracket.
17. Connect the fuel feed hose (see «FUEL LINE/QUICK-CONNECT FITTING INSTALLATION»(ref-333562-S07004954342009072100000) ), then install the quick-connect fitting cover.
18. Install the air cleaner assembly (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-333563-S41422864462009072100000) ).
19. Install the intake air duct (see «AIR CLEANER ELEMENT INSPECTION/REPLACEMENT»(ref-333563-S38299951722009072100000) ).
20. 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.
21. Fill the radiator with engine coolant (see step 11 on «COOLANT REPLACEMENT»(ref-333555-S19429433502009072100000) ), and bleed the air from the cooling system with the heater valve open.
22. Do the CKP pattern clear/CKP pattern learn procedure (see «CKP PATTERN CLEAR/CKP PATTERN LEARN»(ref-333557-S25100768752009072100000) ).

Scheme 198

1. Remove the cylinder head (see «CYLINDER HEAD REMOVAL»(ref-333551-S41411568312009072100000) ).
2. Inspect the camshaft (see «CAMSHAFT INSPECTION»(ref-333551-S06940188432009072100000) ).
3. Check the cylinder head for warpage. Measure along the edges, and three ways across the center. If warpage is less than 0.05 mm (0.002 in.), cylinder head resurfacing is not required. If warpage is between 0.05 mm (0.002 in.) and 0.2 mm (0.008 in.), resurface the cylinder head. Maximum resurface limit is 0.2 mm (0.008 in.) based on a height of 121 mm (4.76 in.). Cylinder Head Height Standard (New): 120.95-121.05 mm (4.762-4.766 in)

Scheme 199

Scheme 200

1. Remove the cylinder head cover (see «CYLINDER HEAD COVER REMOVAL»(ref-333551-S34784543322009072100000) ).
2. Loosen the locknuts and adjusting screws (A).
3. Remove the rocker shaft bridge mounting bolts, the rocker shaft holder mounting bolts, and the rocker arm assembly. Loosen the rocker shaft bridge mounting bolts and the rocker shaft holder mounting bolts in sequence two turns at a time, to prevent damaging the valves or the rocker arm assembly. When removing the rocker arm assembly, do not remove the rocker shaft bridge mounting bolts and the rocker shaft holder mounting bolts. The bolts will keep the rocker arms on the shafts.

1. Remove the cylinder head cover (see «REAR»(ref-333551-S35723280702009072100000) ).
2. Loosen the locknuts and the adjusting screws (A).
3. Remove the rocker shaft bridge mounting bolts, the rocker shaft holder mounting bolts, and the rocker arm assembly. Loosen the rocker shaft bridge mounting bolts and the rocker shaft holder mounting bolts in sequence two turns at a time, to prevent damaging the valves or the rocker arm assembly. When removing the rocker arm assembly, do not remove the rocker shaft bridge mounting bolts and the rocker shaft holder mounting bolts. The bolts will keep the rocker arms on the shafts.
