Cylinder Head Installation

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean the cylinder head and the block surface.
  2. Install a new coolant separator (A) in the engine block whenever the engine block is replaced.

  3. Install the new cylinder head gasket (B) and the dowel pins (C) on the engine block. Always use a new cylinder head gasket.
  4. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with the pointer (B) on the oil pump.

  6. Install the cylinder head on the engine block.
  7. Apply new engine oil to the threads and under the bolt heads of all cylinder head bolts.
  8. Tighten the cylinder head bolts in sequence to 29 N.m (3.0 kgf.m, 22 lbf.ft). Using a beam-type torque wrench. When using a preset-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.

  14. Connect the engine wire harness connectors, and install the wire harness clamps to the cylinder head.
    • Four injector connectors
    • Engine coolant temperature (ECT) sensor 1 connector
    • Camshaft position (CMP) sensor connector
    • Secondary heated oxygen sensor (secondary HO2S) connector
    • Rocker arm oil control solenoid connector
  15. Install the warm up three way catalytic converter (WU-TWC) (see WARM UP TWC REMOVAL/INSTALLATION ).
  16. Install the intake manifold/chamber assembly (see INSTALLATION ).
  17. Install the upper radiator hose (A), the heater hose (B), and the water bypass hose (C).

  20. Install the air cleaner (see AIR CLEANER REMOVAL/INSTALLATION ).
  21. After installation, check that all tubes, hoses, and connectors are installed correctly.
  22. Do the battery installation procedure (see BATTERY REMOVAL AND INSTALLATION ).
  23. 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.
  24. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open (see step 9 on COOLANT REPLACEMENT ).
  25. Clean up any spilled engine coolant.
  26. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure (see CKP PATTERN CLEAR/CKP PATTERN LEARN ).
  27. Inspect the idle speed (see IDLE SPEED INSPECTION ).
  28. Inspect the ignition timing (see IGNITION TIMING INSPECTION ).
