Steel Seal Head Gasket Repair

Part Number: WDSSS

Steel Seal is a proven chemical formula designed to permanently repair blown head gaskets, cracked heads, and engine block damage. Unlike sodium silicate-based products (commonly called “liquid glass”), Steel Seal’s unique blend of compounds reacts under heat and pressure to form a hardened seal that withstands the extreme conditions inside your engine. With over 20 years on the market and a 99% success rate, it is a trusted alternative to costly mechanical repairs.

Recommended Dosage:

  • Up to 2.5L engines – 1 bottle
  • Up to 4.0L engines – 2 bottles
  • Over 4.0L engines – 3 bottles

Treatment Steps:

  1. Ensure engine is cold. Pour Steel Seal into radiator (or expansion tank if no radiator cap).
  2. Turn heater/fan to max, start engine, and run to temperature. Idle for 30 minutes, then allow to cool.
  3. Top up coolant if necessary and drive as usual — Steel Seal remains in the system to complete the seal.

Important: Not compatible with all antifreeze formulations. For best results, use with plain water during treatment and re-add antifreeze afterwards. Always change oil if water is present before proceeding.
