Cylinder Head Installation Left Side

1. Clean the gasket surfaces. Refer to Replacing Engine Gaskets .



2. Inspect the cylinder head locating pins for proper installation.




Important: Do not use sealer on any engines that use a composition type gasket.

Align the gasket locating mark to face up.
3. Place the gasket in position over the cylinder head locating pins.
4. Install the cylinder head to the block.

Guide the cylinder head carefully into place over the locating pins and the head gasket.

5. Apply sealer GM P/N 12346004 or equivalent to the threads of the cylinder head bolts.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Install the cylinder head bolts in sequence:

Tighten

1. Tighten the bolts a first pass to 40 N·m (30 lb ft).
2. Tighten the bolts a second pass to 80 N·m (60 lb ft).
3. Tighten all the long bolts (1, 2, 3, 6, 7, 8, 9, 12, 13, 14, 15 and 16) in sequence to a final pass of 125 N·m (92 lb ft).
4. Tighten all the short bolts (4, 5, 10 and 11) in sequence to a final pass of 120 N·m (89 lb ft).
