RIGHT (REAR) CYLINDER HEAD

TOOL REQUIRED
^ J 36660 Torque Angle Meter

IMPORTANT: During disassembly, keep the valve train components together and identified so that they can be installed in their original locations. Do a compression test and note the results before you do the following repairs:
^ Remove the cylinder head(s).
^ Disassemble the valve mechanism.

Cylinder Head Tightening Sequence:

INSTALL OR CONNECT
1. Place the cylinder head gasket in position over the dowel pins. Ensure the note "This Side Up" is showing.
2. Cylinder head.
3. Coat the cylinder head bolt threads with sealer. Use GM P/N 1052080 sealer or its equivalent.
4. Install the cylinder head bolts. Tighten the bolts to 45 Nm (33 ft. lbs.) in the sequence shown. Use the Torque Angle Meter in order to tighten the bolts an additional 90 degrees.
5. Pushrods.
6. Rocker arms.
7. Rocker Cover.
8. Raise and suitably support the vehicle.
9. Exhaust pipe to manifold.

IMPORTANT: It is recommended that engine oil be drained and crankcase refilled with clean engine oil to avoid possible contamination by engine coolant and/or foreign material when removing cylinder head.

INSPECT
^ Proper fluid levels.
^ For leaks.
