Caution: Excessive sealant can run back into the engine and cause damage to other components. Allow the sealยญant to dry for a minimum of 2 hours before operating the engine.
Apply a 2 mm [1/16 inch] bead of expansion plug lock โN seal, Part No. 3375068, or equivalent to the outside diameter of the expansion plug and the inside diameter of the expansion plug installation bore.
Using an appropriate deep socket as a driver, install the expansion plug.
The expansion plug must be installed with the edge of the expansion plug 0.5 to 1.0 mm [0.020 to 0.040 in] deeper
than the entrance chamber of the bore.
NOTE: Do not install the expansion plug too deep. If the expansion plug is not installed straight and flat, it must be
replaced with a new expansion plug.
