  • HEAD GASKET SEALER: Fix it with Green Demon! Safe for all engines from bikes to trucks. Just shake and pour the gasket liquid sealant into the radiator cap to permanently seal and repair the leak. Green Demon magic takes effect in just a few minutes!
  • JUST ONE APPLICATION REPAIR: No engine flushing or draining required. A super strength ceramic formula flows through the cooling system to reach damaged areas. Particles combine creating a mesh that cures and repairs leaks to form a permanent sealed bond.
  • FIX PERMANENTLY: Find coolant puddles? Get Green Demon in your vehicle to avoid costly repairs. Green Demon fixes head gasket failures from coolant to cylinder/cylinder to coolant leaks, blown head gaskets and coolant to oil leaks (in certain situations).
  • DON’T BLOW A GASKET: Fix it! Stop leaks, easily and safely. Use on Head Gaskets, warped or cracked cylinder heads, engine blocks, radiators, heater cores and freeze plugs. Perfect Do-It-Yourself car solution for those expensive and time-consuming repairs.
  • TRUSTED BY PROFESSIONALS: Scientifically engineered, the Green Demon Head Gasket & Block Repair is road tested and mechanic trusted. Save on repairs and extend the life of your car. Buy with confidence - with our 100% money-back or replacement guarantee.
  • Attention: If you notice bubbles coming from the radiator or coolant reservoir, or if Green Demon engine coolant leak stop isn't sealing, the system might be over-pressurized. Please watch the video on this page for additional instructions to ensure a successful repair.
