NOTE: The cylinder head bolts used on the 2.5L engine can only be used a total of 2 times. Therefore the bolts can only be reused once before new bolts are necessary. If the cylinder head bolts removed from the engine have dabs of paint on their heads, they have already been reused (used twice) and must be discarded; new bolts must be purchased. If the cylinder head bolts do have paint on them, they have not yet been used twice and may be reused at this time. If reusing the cylinder head bolts paint the bolt heads so that they can be identified later on as already reused. New bolts, however, are always recommended by Chilton.
When the cylinder head is removed, check the flatness of the cylinder head gasket surfaces. Since the tools required for resurfacing a cylinder head are extremely expensive and the necessary skills are important, refer to a reputable machine shop for cylinder head refinishing specifications and procedures.
