The date code will be stamped below the reman part number and be in the format of "060 12 1". This indicated the 60th day of 2012, first shift.

If a 0R-2669, or a 0R-2670 Cylinder Head has a date code of "060 12 1" or after, mark the packaging to indicate it has been inspected according to this program and return the cylinder head to dealer parts stock.

If a 0R-2669, or a 0R-2670 Cylinder Head has a date code earlier than "060 12 1", remove the cylinder head from dealer parts stock.

For overhaul kits with a suspect cylinder head, replace the cylinder head with a known good cylinder head from dealer parts stock, or a new reman cylinder head order.

DO NOT return the entire overhaul kit. Only return the cylinder head. Refer to the Parts Disposition.
