The tightening sequence for a three cylinder engine
Illustration 8 g01309552
The tightening sequence for a four cylinder engine
For three cylinder engines, tighten the bolts to a torque of 101 N m (75 lb ft). Use the numerical sequence that is shown in Illustration 7.
For four cylinder engines, tighten the bolts to a torque of 101 N m (75 lb ft). Use the numerical sequence that is shown in Illustration 8.
If necessary, install the water temperature regulator to the cylinder head. Refer to Disassembly and Assembly, "Water Temperature Regulator- Remove and Install".End By:

Thoroughly clean the gasket surfaces of the cylinder head and the cylinder block. Do not damage the gasket surfaces of the cylinder head or the cylinder block. Ensure that no debris enters the cylinder bores, the coolant passages, or the lubricant passages.
Inspect the gasket 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.

Inspect dowels (3) for damage. If necessary, replace the dowels in the cylinder block.
Install Tooling (A) to the cylinder block. Refer to Illustration 9.
Ensure that the new cylinder head gasket (4) is the same thickness as the cylinder head gasket that was previously removed. The thickness of the cylinder head gasket is indicated by the number that is shown at Position (X). Refer to Specifications, "Cylinder Head" for more information.
Align cylinder head gasket (4) with Tooling (A) and with dowels (3). Install the cylinder head gasket onto the cylinder block.
Use a suitable lifting device to lift the cylinder head. The weight of the cylinder head is approximately 30 kg (66 lb).
Use Tooling (A) to align cylinder head (2) with the cylinder block. Install the cylinder head to the cylinder block.Note: Ensure that the cylinder head is correctly positioned onto dowels (3).
Remove Tooling (A).
Install new bolts (1) to cylinder head (2).
