Cylinder Head: Inspection

If the cylinder head has been removed due to an engine overheating concern or a head gasket leak it's very important checking the cylinder head flatness prior installing all parts back to the engine.

Use a straightedge and feeler gauge to check the flatness of the engine cylinder head and engine block mating surfaces.

The cylinder head thickness is 133 ± 0.06 mm (5.2362 ± 0.0023 in.) and the cylinder head flatness tolerance is 0.1 mm (0.0039 in.).

If the cylinder head is out of specification, then the cylinder head must be replaced  .
