Engine - Cylinder Head Bolt Torque Correction

SOURCE: Kia PitStop

TITLE: Cylinder Head Torque, Cam Carrier Information

APPLIES TO: 01 Rio

SERVICE TIP:






The 2001 Rio Service Manual incorrectly specifies cylinder head bolt torque values as 36.1 lb-in and 18 lb-in respectively (before final 90 degree tightening step). While the values are correct, the units should read lb-ft. Please cross out the in and replace it with ft.

Also note that the cylinder head bolts used on Rio engines are of the (stretch) type that must not be re-used, and must be replaced any time they are removed. Follow the procedure when installing cylinder head.

The cam carrier on the Rio engine is align bored with the cylinder head. If either requires replacement, it's necessary to replace both.

The cam carrier also requires an oil tight seal between it and the cylinder head. This is accomplished with 4 special O-ring seals (P/N 0K30E-10-122) around the spark plug cavities, and with a sealant on the mating surfaces.

Note: Kia inadvertently specified sealant to be used on outside surfaces only. This is incorrect. Sealant should be applied to all mating surfaces, while taking care not to allow sealant into oil or coolant passages.

The specified sealant is for close fitting machined surfaces, and eliminates the need to re-torque after the sealant settles and cures. The sealant to be used when replacing or re-installing the Rio's cam carrier is either Hylomar Anaerobic Adhesive Grade 3000 or an equivalent, such as Permatex Anaerobic Gasket Maker.

Future issues of the Parts catalog will list the O-ring seal P/N, while the P/N currently shown for the cam carrier as a separate part will be eliminated. Order the cylinder head/cam carrier assembly if replacement of either is required.
