Cylinder Head Assembly: Service and Repair

Cylinder Head Tightening Sequence & Torque Specifications:

Fig. 7 Rocker Arm Cover, Rocker Arms & Pushrod Replacement:

SPECIAL TOOL REQUIRED (or equivalent)
^ J-36660 Torque/Angle meter.


NOTES:
^ Before removing the cylinder head from the engine and before disassembling the valve mechanism, run a compression test and note the results.
^ During disassembly of the cylinder head, be sure that the valve train components are kept together and identified so that they can be installed in their original locations.

REMOVE OR DISCONNECT

6. Spark plug wires.
7. Throttle control cable bracket at throttle body and rocker cover.
8. Rocker arms.
9. Electrical connections from:
^ Intake manifold.
^ Throttle body.
^ Cylinder head.
^ Oxygen sensor.
10. Power steering pump bracket from intake manifold brace, located under intake manifold.
11. Engine strut bracket from engine and engine strut.
12. Alternator rear bracket at engine.
13. Necessary vacuum lines at intake manifold.
14. Upper radiator hose and heater hose from engine.
15. Raise vehicle and suitably support.
16. Exhaust pipe from exhaust manifold.
17. Lower vehicle.
18. Relieve fuel pressure and disconnect fuel lines at quick disconnects.
19. Transaxle fluid level indicator tube out from intake manifold.
