Installation Procedure

^ Tools Required
- J 36660-A Torque Angle Meter





1. Install the cylinder head gasket.





2. Install the cylinder head.

Notice: Refer to Fastener Notice in Service Precautions.

Notice: This component uses torque-to-yield bolts. When servicing this component, do not re-use the bolts. New torque-to-yield bolts must be installed. Re-using used torque-to-yield bolts will not provide proper bolt torque and clamp load. Failure to install NEW torque-to-yield bolts may lead to engine damage.





3. Install the NEW cylinder head bolts.
- Tighten the NEW cylinder head bolts to 60 Nm (44 lb ft) in the order shown. Use the J 36660-A torque angle meter in order to rotate the cylinder head bolts an additional 95 degrees.

4. Install the engine left side exhaust manifold. Refer to Exhaust Manifold Removal (Right Side).
5. Install the engine left side spark plugs. Refer to Spark Plug Replacement.
6. Install the engine left side spark plug wires to the spark plugs. Refer to Spark Plug Wire Harness Replacement.
