We often get asked, what is the difference between Rislone Head Gasket Fix and Rislone Liquid Copper, which one should I use and when?

Rislone Head Gasket Fix is formulated to repair Head Gasket leaks, it requires no draining of the cooling system and is compatible with all types of antifreeze and coolant, as well as just water. It has a sodium silicate sealing liquid, combined with fibre filler particles, which are small enough to pass through your entire cooling system without clogging it, including the passages of the heater core. The combination of ingredients discovers the leak site, where it bonds together utilizing the extreme head inside of the combustion chamber to form a permanent seal, that is stronger than the original head gasket itself.

When should I use Rislone Head Gasket Fix? If you’re experiencing a head gasket leak, you may notice white exhaust smoke, bubbling in the radiator and coolant reservoir (expansion tank), unexplained coolant loss, a milky colour in your engine oil, decreased acceleration, engine stalling and engine overheating. If you’re experiencing one or all of the above mentioned issues, and you are able to idle your vehicle for 20 minutes without it overheating or without having to add more coolant, then your vehicle is a good candidate for successful treatment with this product. Rislone Head Gasket Fix is suitable for use on aluminium and cast iron heads and blocks, and is also very successful at treating other engine cooling system leaks along the way.

Rislone Liquid Copper Block Seal is also a sodium silicate formula, which features slightly less sodium silicate than the Rislone Head Gasket Fix, the fibres in the formula also behave differently, they are small enough to pass through all the internal passages in your cooling system, including the heater core. When these fibres and sealing liquid discover the leak, they pass through the leak site and when they meet the air, the fibres expand, and bond together to eventually bridge the gap and seal the leak.

When should I use Rislone Liquid Copper Block Seal? If you’re experiencing unexplained loss of coolant, engine overheating or you have an intake manifold or block leak, this would be the correct product to choose. Block leaks, often have similar symptoms to a head gasket leak which can include oil and antifreeze mixing together, which can lead to a milky colour in your engine oil. If your block has a crack, you may experience emissions fumes escaping through the engine block rather than the exhaust, engine overheating, and low compression.

While both of these products require no draining of the cooling system, it is recommended to flush with a chemical flush such as Rislone Radiator 10 Minute Flush or Rislone Super Radiator Flush, if you are unsure when the cooling system was last flushed and refilled, or if another cooling system stop leak product has been installed, or if the radiator cooling system is partially blocked, or particularly dirty with scale and rust deposits.
