 Works On:
    Cracked Cylinder Heads     Gasoline and Diesel Engines
    Blown Head Gaskets     Cast Iron or Aluminum Blocks & Heads

Prepares system for sealing by cleaning the entire cooling system including the blown or cracked area where engine contaminants entered the cooling system.

A clean cooling system is the foundation for maintaining the proper temperature control necessary to promote the adhesion of Head Gasket & Block Sealant and insure the longevity of the seal.

  1. Allow engine to cool. Drain cooling system removing all antifreeze.
  2. Shake well and add entire bottle of Cooling System Prep & Cleaner to the radiator.
  3. Refill system with water and reinstall radiator cap. Start vehicle. After engine reaches normal operating temperature (thermostat opens), run for 10 minutes with heater on high and air conditioning off.
  4. Turn vehicle off and allow engine to cool. Flush cooling system and reservoir until water runs clear.
  5. Drain system and move on to Step 2, Head Gasket & Block Sealant.

Sealant penetrates cracks and damaged or blown head gasket area, drying to form a seal stronger than the original head gasket itself. High strength fibers work like rebar in concrete to create a truly permanent seal.

 

Permanently:

  • Seals Cracked Cylinder Heads

  • Repairs Blown Head Gaskets

  • Stops All Block Leaks
  1. Shake well. Mix Head Gasket & Block Sealant in bucket or container with approximately 2 quarts of water. Pour this mixutre directly into the cooling system.
  2. Fill cooling system with water and reinstall radiator cap.
  3. Turn heater on high and air conditioning off.
  4. Start vehicle and run engine until thermostat opens or normal operating temperature is reached.
  5. Turn vehicle off and top off cooling system with water when radiator cap can safely be removed. Reinstall radiator cap.
  6. Run engine at idle for 15 minutes. Turn vehicle off and allow to cool.
  7. Top off cooling system with water as needed an reinstall radiator cap.
  8. Run engine at high idle (1500 RPM's) for 20 minutes.
  9. Idle engine for 30 minutes. Turn vehicle off and allow to cool.
  10. Drain and flush system and move to Step 3, Head Gasket & Block Treatment.

Antifreeze compatible treatment that protects & conditions the head gasket and all cooling system parts sealing and preventing future leaks.

  1. Shake well. Pour Head Gasket & Block Treatment directly into radiator.
  2. Refill cooling system with manufacturer's recommended antifreeze/water mixture.
  3. Start vehicle and run engine until thermostat opens or normal operating temperature is reached.
  4. Turn vehicle off and top off cooling system with antifreeze/water mixture when radiator cap can safely be removed. Leave Head Gasket & Block Treatment in cooling system for continued protection. Drive vehicle as normal.
