GASKET GUARD®

Repair • Protect • Drive

GASKET GUARD® is a professional-grade 2-in-1 solution designed to permanently seal blown head gaskets and protect your engine from future failure. Utilizing Advanced Nanotechnology, this formula detects leaks and creates a high-strength seal without the need for a costly engine teardown.

  • ✔ CO2 & HEAT ACTIVATED: Specifically engineered to react to High Pressure CO2 and extreme combustion temperatures. It remains liquid in the coolant elsewhere, ensuring it WILL NOT CLOG your heater matrix or thermostat.
  • ✔ PERMANENT WELD: Creates a chemical bond to seal cracked cylinder heads and blown gaskets. Once cured, the high pressure permanent seal withstands extreme engine pressures.
  • ✔ NO DRAINING REQUIRED: Simply pour directly into the expansion tank or radiator (when cold). Compatible with all types of antifreeze/coolant and all petrol or diesel engines.
  • ✔ THE ULTIMATE PROTECTION: Leave in the system for ongoing protection against future overheating and hairline cracks before they cause engine failure.

How to Use

  1. POUR: Ensure engine is cold. Pour directly into radiator or expansion tank.
  2. IDLE: Run engine for 15-20 mins with heater on MAX to circulate formula.
  3. DRIVE: Seal is permanent—continue driving as usual.
