Tools Required

J 36660-A Torque Angle Meter

1. Install the NEW cylinder head gasket.

Install the gasket over the locating pins, with the yellow side of the tab on the outboard side facing up.




2. Install the cylinder head over the locating pins and the gasket.



3. Apply sealant GM P/N 12346004 or equivalent to the threads of the NEW 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.

4. Install the NEW cylinder head bolts finger tight.

Tighten
Tighten the cylinder head bolts on the first pass in sequence to 30 N·m (22 lb ft).
