Cylinder Head Removal
Cylinder Head RemovalSpecial Tool Required
^ Belt Tension Release Arm, YA9317, commercially available
Engine removal is not required this procedure.
NOTE:
^ 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 100°F (38°C) before loosening the retaining 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.
1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.
2. Disconnect the battery negative terminal.
3. Drain the engine coolant.
4. '98-99 models: Remove the throttle body cover (A), ignition wire cover (B) and intake manifold covers (C).
'00-02 models: Remove the throttle body cover (A), intake manifold covers (B) and intake manifold cover stay (C).
5. Remove the Evaporative Emission (EVAP) canister hose (A) from the throttle body.
6. Remove the vacuum hose (B) and breather pipe (C), then remove the intake air duct (D).
7. Remove the throttle cable (A) and cruise control cable (B) by loosening the locknuts (C), then slip the cable ends out of the accelerator linkage. Take care not to bend the cables when removing them. Always replace any kinked cable with a new one.
8. Relieve fuel pressure.
9. Remove the fuel feed hose (A) and fuel return hose (B).
10. Remove the brake booster vacuum hose (A), vacuum hoses (B) and Positive Crankcase Ventilation (PCV) hose (C).
11. Remove the vacuum hose (A), ('98-99 models) breather hose (B) and water bypass hoses (C).
12. Remove the ground cable (A).
13. Move the auto-tensioner (B) with the belt tension release arm (C) to remove tension from the alternator belt (D), then remove the alternator belt.
14. Support the engine with a jack and wood block under the oil pan.
15. Remove the side engine mount bracket.
16. Loosen the adjusting nut (A), then remove the locknut (B) and mounting bolt (C). Remove the Power Steering (P/S) pump belt (D) and pump without disconnecting the P/S hoses.
17. Remove the P/S hose clamp (E).
18. Remove the alternator.
19. Remove the engine wire harness connectors and wire harness clamps from the cylinder heads and the intake manifold.

20. Remove the spark plug caps and distributor from the cylinder heads.
21. Remove the intake manifold.
22. Disconnect the six injector connectors.
23. Remove the fuel rails.
24. Remove the vacuum hoses (A) from the intake air bypass control thermal valve (B).
25. Remove the timing belt.
26. Remove the upper radiator hose (A) and lower radiator hose (B).
27. Remove the heater hoses.
28. Remove the front and rear exhaust manifolds.
29. Remove the water passage.
30. Remove the camshaft pulleys (A) and back covers (B).
31. Remove the cylinder head covers.
32. 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.
33. Remove the cylinder heads.
