A pipe plug threads into a tapered threaded port and seals it shut. Signs it may need replacing include seepage around the plug, stripped or corroded threads, or a rounded head that a wrench can no longer grip. Before installing, check the vehicle service information for whether thread sealant is called for and the correct tightening procedure.
