1. 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.
2. Inspect the mating surface of the cylinder head
for distortion. Refer to Specifications Manual,
"Cylinder Head" for more information. If the mating
surface of the cylinder head is distorted beyond
maximum permitted limits, replace the cylinder
head.
3. If necessary, install the inlet manifold to the
cylinder head. Refer to Disassembly and
Assembly Manual, "Inlet manifold - Remove and
Install".

4. Inspect the dowels (18) for damage. If necessary,
replace the dowels in the cylinder block.
5. Install Tooling (A) to the cylinder block.
6. Align the cylinder head gasket (17) with the

7. Use a suitable lifting device (16) to lift the 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.
8. Use Tooling (A) to align the cylinder head with
g01177295
the cylinder block. Install the cylinder head to the
cylinder block.
Note: Ensure that the cylinder head is correctly
positioned on the dowels (18).
9. Remove Tooling (A).

10. Clean the setscrews (14). Follow Steps 10.a and
10.b for the procedure to inspect the setscrews.
