CAUTION: Before removing the cylinder heads, allow the engine to cool down to room temperature. Never remove a cylinder head from a hot/warm engine. The cylinder head may warp.

NOTE: When removing the cylinder head, the exhaust manifolds must be removed from the cylinder head. Install the exhaust manifolds AFTER the cylinder head and gasket have been installed.This is to prevent damage to the cylinder head gasket tabs.

RIGHT CYLINDER HEAD REMOVAL (ENGINE INSTALLED)
1. Disconnect the battery negative cable.
2. Drain the cooling system. Refer to Cooling System/Service and Repair for procedure. Service and Repair

3. Remove the intake manifold. See Intake Manifold/Service and Repair. Service and Repair

4. Remove A/C Pump (if so equipped).
5. Remove the exhaust manifold.
6. Remove the cylinder head cover.
7. Remove the spark plug wires from the cylinder head.
8. Remove the top alternator mounting bracket that bolts to the cylinder head and the timing case cover.
9. Remove the timing case bolts that thread into the cylinder head and those bolts in-line below.

NOTE: The timing chain and sprocket must be held In place and not allowed to drop down while the cylinder head is removed. If the chain and sprocket slip, the timing case must be removed and the chain tensioners released.

10. Turn the engine over until the camshaft sprocket dowel is straight up.

Fig. 1 Camshaft Sprocket Support Special Tool 7317:

11. Attach Tool 7317 to the timing case cover. Secure with two short cylinder head cover bolts. The tool consists of a support bracket and a dummy bearing Fig. 1.

Fig. 2 Positioning Special Tool 7317:

12. Position the adjusting lever behind the camshaft sprocket. Thread the adjusting lever bolt through the front of the tool, sprocket and into the lever Fig. 2. Push the lever up as far as possible. Tighten the adjusting lever bolt.

Fig. 3 Timing Case Cover Plug:

13. Unthread the plug in the front of the timing case cover Fig. 3. This will give access to the camshaft sprocket bolt.
14. Remove the cylinder head bolts.

Fig. 4 Rocker Arm Shaft Assembly:

15. Remove the rocker arm shaft assembly Fig. 4. The caps are pinned into the top of the cylinder head and will only go on in one direction.
16. Install one head bolt in the center and-tighten about 2 turns.
17. Remove the camshaft c9ver and gasket at the rear of the cylinder head.

Fig. 5 Camshaft Thrust Plate Bolt:

18. Loosen the camshaft thrust plate bolt Fig. 5. Pull the plate up and tighten the bolt. This will allow the camshaft to move back as the sprocket bolt is removed.
19. Loosen the camshaft sprocket both and pull the camshaft back until the bolt is out of the camshaft. The bolt will stay in the sprocket hole: It will not drop down because the timing case cover is too close for it to come out of the sprocket.
20. Slide the camshaft back away from the sprocket.

Fig. 6 Tap Dowel Into Block:

21. Use a long thin drift punch as a tool and insert it into the front and rear cylinder head bolt holes on the exhaust manifold side of the head. Fig. 6. Tap the dowels down below the head gasket.

CAUTION: Do not lift/pry the cylinder head straight up. This will cause the cylinder liners to come up and out of the block.

Fig. 7 Cylinder Head Removal:

22. Position a small piece of wood against the rear intake manifold side of the cylinder head and strike it with a hammer. Now position the piece of wood against the front exhaust manifold side of the cylinder head and strike it with a hammer. Repeat until the cylinder head is loose Fig. 7.
23. Remove the cylinder head bolt.
24. Remove the cylinder head.
25. Remove the cylinder head gasket.

CAUTION: Never rotate the engine with the support bracket of tool 7317 installed.

26. Install liner clamps (Tool 7315) between the cylinder liners to hold them in place.

Fig. 8 Dowel Extractor Special Tool 7314:

27. Use tool 7314 to remove the cylinder head locating dowels Fig. 8.
28. Stuff the tops of the cylinder bores with clean lint free shop towels.
29. Remove the liner hold down clamps (Special Tool 7315) to clean the cylinder block, then reinstall the liner clamps.
30. Use a gasket removal compound to soften the old gasket material.

CAUTION: When cleaning the cylinder head and block mating surfaces, do not use a metal scraper because the surfaces could be cut or ground. Instead, use a wooden or plastic scraper.

Fig. 9 Oil Feed And Return Holes:

31. Make sure the gasket and/or foreign material does not enter the oil feed hole or the oil return hole Fig. 9.
32. Rinse and wipe clean the cylinder block and cylinder head mating surfaces.
33. Check the liner protrusion. The liner protrusion should be between 0.05 mm and 0.12 mm (.002 in. and .005 in.).
