Rislone Block Seal Head Gasket Fix product is the easiest solution to stop head gasket coolant leaks. No draining of the cooling system is required.

Rislone Block Seal Head Gasket Fix contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles which penetrate gaps and cracks and harden to permanently stop leaks. Rislone Head Gasket Fix seals because of the extreme heat inside the combustion chamber (2760°C) which works as a catalyst to permanently harden the material to make it stronger than the actual head gasket itself.

Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Use on all water-cooled petrol and diesel engines. Heavy duty formula works on aluminium and cast iron heads and blocks, along with sealing all other engine cooling system leaks better than traditional stop leak products.

How Does A Cooling System Work?

Coolant, which is a mixture of water and ethylene glycol (Antifreeze), is pumped throughout the engines water jacket, drawing heat from the head, pistons, combustion chambers, cylinder walls, valves, etc. The heated coolant travels from the water jacket through a radiator hose, to the radiator where, aided by a fan, it’s air cooled and returned via the other radiator hose to the engine.

Fuel is saved and engine life increased when the cooling system quickly reaches and maintains a very narrow operational range regardless of outside temperature extremes or engine load demands. Upon engine start up, the temperature must rise quickly, and then remain balanced – not too hot and not too cold. It’s important to understand how the condition of the coolant and the condition of the cooling system components can affect the operational economy and life of your engine.

Directions

  • Allow engine to cool. Make sure engine is cool enough so radiator cap can be safely removed Shake well. Pour Head Gasket Fix directly into radiator. If using in a small cooling system under 5.7 litre capacities, such as 4 cylinders with no air conditioning, install ½ bottles

  • Fill radiator and overflow tank to proper level and reinstall radiator cap
  • Start engine
  • Turn heater on hot and fan on high
  • Idle engine for 15 minutes
  • Allow engine to cool so cap can be safely removed
  • Top off radiator and leave Rislone Head Gasket Fix in cooling system for continued protection. Drive vehicle as normal.

Note: cooling systems that are dirty or partially clogged should be flushed before usage. Protect from freezing. Protect bottle from freezing.

This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs.

How Does This Type Of Product Work?

This formulation contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles which penetrate gaps and cracks and harden to permanently stop leaks.

What If I Don’t Have Direct Access To The Radiator?

If direct access to radiator is unavailable and if reservoir / overflow tank is pressurised, you can install in tank. Otherwise remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.

Do I Need To Drain My Radiator After The Leak Has Been Repaired?

No, top off radiator and leave Rislone Head Gasket Fix in cooling system for continued protection and drive vehicle as normal.

What are the dosage recommendations? One 680g bottle treats cooling systems from 5.6L to 15L. Use 1⁄2 bottle for smaller cooling systems from 3.78L to 5.5L. For larger systems use one bottle for every 15L.

I Accidentally Added The Rislone Head Gasket Fix Into My Fuel Tank. What Should I Do?

Rislone Head Gasket Fix is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head, keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine apart to clean all of the parts.
