Gradually loosen bolts (1) in reverse numerical order. This order will prevent distortion of the cylinder head.For three cylinder engines, loosen the cylinder head bolts in the reverse order to the sequence that is shown in Illustration 4.For four cylinder engines, loosen the cylinder head bolts in the reverse order to the sequence that is shown in Illustration 5.
Remove bolts (1) from cylinder head (2).Note: Type Two bolts must be discarded.
Attach a suitable lifting device to cylinder head (2). The weight of the cylinder head is approximately 30 kg (66 lb). Carefully lift the cylinder head off the cylinder block.Note: Do not use a lever to separate the cylinder head from the cylinder block. Take care not to damage the machined surfaces of the cylinder head during the removal procedure. Avoid contamination of the cylinder bores with coolant or with debris.
Place the cylinder head on a surface that will not scratch the face of the cylinder head.
Remove the cylinder head gasket.Note: The old gasket for the cylinder head should be retained for identification. Gaskets of different thickness are available. Refer to Specifications, "Cylinder Head" for further information.
