NOTICE |
---|
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. Do not damage the mating surfaces of the cylinder head of the cylinder block. Ensure that no debris enters the cylinder bores, the coolant passages, or the lubricant passages.
- Inspect the mating surface of the cylinder head for distortion. Refer to Specifications, "Cylinder Head" for more information. If the mating surface of the cylinder head is distorted beyond maximum permitted limits, replace the cylinder head.
- If necessary, install the inlet manifold to the cylinder head. Refer to Disassembly and Assembly, "Inlet manifold - Remove and Install".

Illustration 2 g01340086 Typical example - Use a suitable lifting device (16) to lift cylinder head (15). The weight of the cylinder head is approximately
66 kg (145.5 lb) .Note: A spreader bar must be used in order to distribute the weight of the cylinder head during the lifting operation.
- Use Tooling (A) to align the cylinder head with the cylinder block. Install the cylinder head to the cylinder block.
Note: Ensure that the cylinder head is correctly positioned on dowels (18).
- Remove Tooling (A).

- Slide the locking tab into the locked position.
- Follow Steps 21.a and 21.b in order to connect harness assembly (4) to boost pressure sensor (6).
- Connect harness assembly (4) to boost pressure sensor (6).
- Slide the locking tab into the locked position.
- Follow Steps 22.a and 22.b in order to connect harness assembly (4) to coolant temperature sensor (5).
- Connect harness assembly (4) to coolant temperature sensor (5).
- Slide the locking tab into the locked position.
- Use new cable straps in order to secure the harness assembly to the cylinder head and to the inlet manifold. Ensure that the harness assembly is not strained.
Note: Ensure that the harness assembly is clear of other engine components.
- Install the inlet hose to inlet connection (3) on inlet manifold (2).
