Tighten

•	Tighten the cylinder head bolts (1-8) in sequence to 60 N·m (44 lb ft).

•	Use the J 36660-A in order to turn the cylinder head bolts (1-8) in sequence an additional 95 degrees.

4. Install the left (front) exhaust manifold. Refer to Exhaust Manifold Replacement .
5. Install the left (front) spark plugs. Refer to Spark Plug Replacement .
