A damaged expansion plug can allow coolant or oil to leak, leading to overheating or contamination. During inspection, an expansion plug may show signs of corrosion or deformation that compromise its seal. The plug's plain mechanical function is to seal a core hole in a cast component, preventing fluid loss. Keeping an expansion plug in sound condition helps avoid sudden system failures that require costly repairs.
