Cylinder Head Removal

• Use fender covers to avoid damaging painted surfaces.
  
• To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
  
• To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 38°C (100°F) before loosening the cylinder head bolts.
  
• Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or hoses, or interfere with other parts.
  
• Keep the cam chain away from magnetic fields.
  

1.	Drain the engine coolant.

2.	Remove air cleaner housing.

3.	Remove the water bypass hoses.

4.	Remove the upper radiator hose (A) and lower radiator hose (B).

5.	Remove the heater hoses.

6.	Remove the drive belt.

7.	Remove the intake manifold.

8.	Remove the exhaust manifold.

9.	Remove the engine wire harness connectors and wire harness clamps from the cylinder head. Four injector connector Engine Coolant Temperature (ECT) sensor connector Top Dead Center (TDC) sensor connector Radiator fan switch connector Oil pressure switch connector Knock sensor connector

10.	Remove the fuel rail.

11.	Remove the air cleaner housing bracket (A), ground cable (B) and harness holder mounting bolt (C), then remove the harness holder (D) from the bracket.

12.	Remove the connecting pipe (A), water bypass hose (B) and Positive Crankcase Ventilation (PCV) hose (C).

13.	Remove the cylinder head cover.

14.	Remove the alternator bracket mounting bolt and loosen the alternator mounting bolt.

15.	Remove the idler pulley (with A/C compressor).

16.	Turn the crankshaft pulley so its TDC mark lines up with the pointer.

17.	Remove the water pump pulley.

18.	Remove the crankshaft pulley.

19.	Disconnect the Crankshaft Position (CKP) sensor connector, then remove the harness clamps.

20.	Support the engine with a 300 x 300 x 25 mm (12 x 12 x 1 in.) piece of wood and jack under the oil pan. NOTE: Do not attach a jack on the center of the oil pan to avoid damage to the oil pan.

21.	Remove the ground cable, then remove the side engine mount/bracket assembly.

22.	Keep alternator away of the chain case. Remove the chain case.

23.	Make a reference mark (A) across the camshaft sprocket and cam chain.

24.	Loosely install the crankshaft pulley.

25.	Apply engine oil to the slider surface of the cam chain tensioner slider through the oil return hole in the cylinder head.

26.	Hold the crankshaft pulley and set the socket wrench (A) on the camshaft sprocket bolt.

27.

Turn the camshaft clockwise to compress the cam chain tensioner, then install the 6 x 1.0 mm bolt (B) in the bolt hole (C) on the cylinder block through the cam chain tensioner (D). NOTE: Turning torque should not exceed 44 N·m (4.5 kgf·m, 33 lbf·ft), when turning the camshaft. Do not turn the camshaft counterclockwise.

28.	Hold the camshaft with an open-end wrench, then remove the camshaft sprocket.

29.	Remove a bolt securing the cam chain guide.

30.	Remove the cylinder head bolts. To prevent warpage, unscrew the bolts in sequence 1/3 turn at a time; repeat the sequence until all bolts are loosened. CYLINDER HEAD BOLTS LOOSENING SEQUENCE:

31.	Remove the cylinder head.
