Expansion/Freeze Plug: Service and Repair
REMOVAL
1. Use Slide Hammer to remove the cylinder block core plug.

damaged, bore for the next oversize plug.
NOTE: Oversize plugs are identified by the "OS" stamped in the flat located on the cup side of the plug.
3. Coat the cylinder block core plug and bore lightly with Thread Lock 262 E2FZ-19554-B or equivalent meeting Ford specification
WSK-M2G351-A6 and install the cylinder block core plug.
