What It Helps Fix

• Seepage around aging engine expansion plugs
• Service issues during engine rebuilds and block restoration
• Replacement needs on GM cylinder block components

Installation Notes and Tips

Install during engine service when the cylinder block is accessible and the plug bore is clean and free of debris. Verify the bore size and application before installation, and follow the vehicle service manual for proper seating and sealing procedures. For best results, inspect adjacent cooling-system components while the engine is apart.
