Removal

CYLINDER HEAD ASSEMBLY








COMPONENTS

REMOVAL
Engine removal is not required for this procedure.

CAUTION: Use fender covers to avoid damaging painted surfaces. To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
^ Mark all wiring and hoses to avoid mis-connection.
^ Inspect the timing belt before removing the cylinder head.
^ Turn the crankshaft pulley so that the No. 1 piston is at top dead center.





1. Disconnect the negative terminal from the battery.
2. Remove the engine cover.
3. Drain the engine coolant. Remove the radiator cap to speed draining.
4. Remove the intake air hose and air cleaner assembly.
1) Disconnect the AFS connector.
2) Disconnect the breather hose from air cleaner hose.
3) Remove the intake air hose and air cleaner assembly.





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





6. Remove the heater hoses (A).
7. Remove the engine wire harness connectors and wire harness clamps from the cylinder head and the intake manifold.

8. Remove the fuel inlet hose (A) from delivery pipe.
9. Remove the PCSV hose.





10. Remove the brake booster vacuum hose (A).
11. Remove the accelerator cable by loosening the lock nut, then slip the cable end out of the throttle linkage.





12. Remove the PCV hose (A).
13. Remove the intake manifold.
14. Remove the power steering pump.
15. Remove the exhaust manifold.
16. Remove the timing belt.
17. Remove the spark plug cable.





18. Remove the cylinder head covers (A).
19. Remove the camshaft sprocket.








20. Remove the camshaft bearing caps (A).








21. Remove the camshafts (A).





22. Remove the timing belt rear cover (A).





23. Remove the water temperature control assembly (A) and water pipe.
24. Remove the cylinder head bolts, then remove the cylinder heads.





1) Uniformly loosen and remove the 8 cylinder head bolts on each cylinder head in several passes and in the sequence shown, then repeat for the other side, as shown. Remove the 16 cylinder head bolts and plate washer.

CAUTION: Head warpage or cracking could result from removing bolts in an incorrect order.

2) Lift the cylinder head from the dowels on the cylinder block and place the cylinder head on wooden blocks on a bench.

CAUTION: Be careful not to damage the contact surfaces of the cylinder head and cylinder block.
