For 1990-2009 cars

#### Tool Required

J 36660-A Torque Angle Meter

Notice: This engine uses special torque to yield head bolts. This design bolt requires a special tightening procedure. Failure to follow the given procedure will cause head gasket failure and possible engine damage.

1. Clean the threads in the cylinder block.
2. Install a new cylinder head gasket on the cylinder block.

Important: The cylinder head gasket must be installed with the stamp markings facing upward (1).

3. Carefully install the cylinder head on the cylinder block.

Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

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 cylinder head bolts and washers into the cylinder head.
5. Progressively torque the cylinder head bolts using three steps in the sequence shown.

1st Pass
Tighten the cylinder head bolts to 25 N·m (18 lb ft).

2nd Pass
Tighten the cylinder head bolts to 49 N·m (36 lb ft).

3rd Pass
After reaching the torque of 49 N·m (36 lb ft). Use a J 36660-A Torque Angle Meter and tighten the cylinder head bolts an additional 90 degrees.
