Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
- Thoroughly clean the mating surfaces of the cylinder head and the cylinder block.
- Clean all 26 head bolt holes on the cylinder block with Tooling (E) .
- After cleaning the threads, remove any debris from the head bolt holes on the cylinder block with a vacuum hose.
- Visually inspect the head bolt holes on the cylinder block for thread damage.
- If a damaged head bolt thread is observed, repair the damaged head bolt thread with a Heli-Coil thread repair kit.
- Inspect the cylinder head and the cylinder block for flatness. Refer to Guideline for Reusable Parts and Salvage Operations, SEBF8162, "Procedure to Measure and Salvage Cylinder Head Assemblies and Related Components".
- Install the new O-ring seals and the new cylinder head gasket on the cylinder block.
- Attach a suitable lifting device to cylinder head (3). The weight of the cylinder head is approximately 295 kg (650 lb). Position cylinder head (3) on the cylinder block.

- Install new bolts (2) .
- Lubricate the following components with Tooling (F) : the bolt threads, the underside of the bolt heads and the washers. Follow Step 11 for the correct tightening procedure.
- Tighten the cylinder head bolts according to the following procedure:
- Tighten bolt (1) through bolt (26) in a numerical sequence to a torque of 160 ± 15 N·m (120 ± 11 lb ft).
- Tighten bolt (1) through bolt (26) again in a numerical sequence to a torque of 160 ± 15 N·m (120 ± 11 lb ft).
- Place an index mark on each bolt head. Turn bolt (1) through bolt (26) in a numerical sequence for an additional 90 degrees (1/4 turn).
- Loosen bolt (1) through bolt (26) until the washers are loose under the bolt heads.
- Tighten bolt (1) through bolt (26) in a numerical sequence to a torque of 160 ± 15 N·m (120 ± 11 lb ft).
- Tighten bolt (1) through bolt (26) again in a numerical sequence to a torque of 160 ± 15 N·m (120 ± 11 lb ft).
- Place an index mark on each bolt head. Turn bolt (1) through bolt (26) in a numerical sequence for an additional 90 degrees (1/4 turn).
- Tighten bolt (27) through bolt (33) in a numerical sequence to a torque of 28 ± 7 N·m (20 ± 5 lb ft).
