Removal and Installation

REMOVAL
1. Remove crankshaft damper.
2. Remove timing belt covers.
3. Remove camshaft sprockets.
4. Remove intake manifold assembly.





5. Remove rear timing belt cover to cylinder head fasteners. Remove the rear covers.





6. The right side timing belt cover has O-rings located behind it for water pump passages.
7. Remove cylinder head bolts and remove cylinder head.





NOTES:
- The cylinder head bolts are tightened using a torque-to-yield procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts should be replaced.

- Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt should be replaced.

INSTALLATION
1. Before installing the bolts the threads should be oiled with engine oil.

Head Gaskets:

2. Install head gasket over locating dowels. Ensure the gasket is installed on the correct side.
3. Install cylinder head over dowels.

Cylinder Head Torque Sequence:

4. Tighten the cylinder head bolts in the sequence shown in the illustration. Using the 4 step torque-turn method, tighten according to the following values:
- First All to 61 Nm (45 ft. lbs.)
- Second All to 88 Nm (65 ft. lbs.)
- Third All (again) to 88 Nm (65 ft. lbs.)
- Fourth + 1/4 Turn Do not use a torque wrench for this step.
5. Bolt torque after 1/4 turn should be over 90 ft. lbs. in the tightening direction. If not, replace the bolt.
6. Install rear timing belt covers. Use new O-ring on the water pump passages on the right side cover. Tighten bolts to specified torque:
- M10-54 Nm (40 ft. lbs.)
- M8-28 Nm (20 ft. lbs.)
- M6-12 Nm (105 inch lbs.)
7. Install timing belt.
8. Install timing belt covers.
9. Install intake and exhaust manifolds.
10. Install crankshaft damper.
