An engine component seal assembly and method of sealing a coolant passage from an engine component are provided. The seal assembly includes a sealing sleeve sized and dimensioned to slip fit into an engine component mounting bore and a retaining ring sized and dimensioned to be axially inserted into the sleeve. The ring contacts the sleeve and applies a radial force sufficient to create an interference fit and to move or yield an interface portion of the sleeve radially outward into sealing abutment against a wall forming the mounting bore to create a secure and reliable annular fluid seal.
