  • Stops Leaks
  • Repairs
  • One Step, No Draining Required
  • Antifreeze Compatible Sodium Silicate Formula
  • Permanent Cooling System Repair
  • Works with All Types of Antifreeze or Water

Rislone Liquid Copper™ Block Seal Intake & Radiator Stop Leak seals larger leaks regular stop leaks won’t. One step formula permanently repairs larger leaks in radiators, intake manifolds & gaskets, heater cores, blocks, heads and welch plugs. Use on cars, trucks, vans, utes, SUV’s and RV’s.

One “1” Step Sealer contains an antifreeze compatible sodium silicate liquid glass formula, so no draining of the cooling system is required. It will not harm the cooling system when used properly. Use with all types of 50-50 mix antifreeze including conventional green or blue (Silicate-based) and extended life red/orange or yellow (OAT /HOAT) coolant.

PERMANENTLY FIXES COOLING SYSTEM LEAKS

Sealing Liquid

Stop Leak Fibres

Liquid penetrates large and small leaks
in plastic, aluminium and cast iron intakes, heads, blocks and radiators.

Fibre additives lock together with liquid to increase strength and promote a permanent seal in
gasket leaks.

PURPOSE OF A COOLING SYSTEM

Your engine creates up to 2760° C of heat within the combustion chamber. Enough heat to melt the entire engine in less than 30 minutes! Approximately one third of fuel’s energy is converted into usable power to propel the vehicle, one third of the energy is dissipated out through the exhaust system, and the remaining one third is carried off by the cooling system.

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, its 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!

DOSAGE:
Use – 1/2 (half) bottle in a small cooling system, such as 4 cylinders with no A/C.
For other small systems use approximately 20 mL per litre of cooling capacity.
Use 1 (one) bottle for regular size systems, which are for most 4, 6, 8 and 10 cylinder engines.
For larger systems, use 1 bottle for every 23 litres of cooling system capacity.

DISPOSAL:
Observe local laws and regulations. Where permitted, dispose of in sanitary sewer systems. Never pour onto the ground or storm sewer system.

NOTE:
Cooling systems that are dirty or partially clogged should be flushed before usage. Protect from freezing.

DIRECTIONS:

  1. Allow engine to cool. Make sure engine is cool enough so radiator cap can be safely removed.
  2. Shake well. Pour LIQUID COPPER™ BLOCK SEAL directly into radiator. If using in a small cooling system, such as 4 cylinders with no air conditioning, install ½ of bottle. TIP: When you do not have access to your radiator, remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp. If you have a pressured overflow tank, you can install in tank.
  3. Fill radiator and overflow tank to proper level and reinstall radiator cap.
  4. Turn heater on hot and fan on high.
  5. Start vehicle and idle engine for 10 to 15 minutes.
  6. Turn vehicle off and allow engine to cool until safe to open cap.
  7. Top off radiator and leave Rislone LIQUID COPPER™ in the cooling system for continued protection. Drive vehicle as normal.

NOTE:
For severe leaks, like a blown head gasket, it is recommended to use Rislone Head Gasket Fix.

FREQUENTLY ASKED QUESTIONS

Can Rislone® Liquid Copper™ Intake & Radiator Stop Leak be installed in existing antifreeze?
Yes, unlike other copper stop leak products, Liquid Copper™ One Step sealer contains an antifreeze compatible sodium silicate formula, so draining of the cooling system is not required as long as manufactures recommendations are followed. It also can be used in water alone however, a second bottle of Liquid Copper™ is recommended to be added to the system once antifreeze is installed.

Will it work in the new extended life antifreeze?
Yes, Liquid Copper™ is compatible with both conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) 50-50 mix antifreeze.

Do I need to drain my cooling system after using Liquid Copper™?
No, this product is designed to be left in the cooling system to protect from future leaks.

How does this type of product work?
It stops leaks by forming a physical plug with organic and synthetic fibres, copper and an ionic modified mineral. The plug forms as the coolant and sealer flow out of the leak. A wetting agent cleans the sides of the hole and prepares the surface for bonding. The first fibres catch on the side of the leak or hole eventually bridging the entire hole. The fibres now act as a sieve trapping more fibres, copper particles and minerals, creating a composite plug. This plug is stabilized or cemented with a liquid glass. The liquid glass hardens with increased temperature and completes the seal.

How long does it take to see results?
Results should be noticeable within 20 to 30 minutes. If the leak is not sealed in 30 minutes of running, mechanical repair may be needed.

What are the dosage recommendations?
Use 1 (one) bottle for regular size cooling systems, this covers most 4, 6, 8 and 10 cylinder engines. For small cooling systems, such as 4 cylinders with no air conditioning, use ½ (half) of bottle. For other small systems use approximately 20 mL per litre of cooling capacity. In larger systems, use 1 (one) bottle for every 23 litres of cooling system capacity.

Will Liquid Copper™ plug my heater core?
No, Liquid Copper™ will not plug a clean heater core. Note: If using Rislone to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.

Can I install Liquid Copper™ in my overflow reservoir?
For best results Liquid Copper™ should not be installed in a regular overflow tank unless it has a screw on pressurized cap. If you do not have access to your radiator, remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.

Will this work in both domestic and import cars and trucks?
Yes, Liquid Copper™ will work in all types of water cooled vehicles.

I accidentally added the Liquid Copper™ into my petrol tank, what should I do?
Liquid Copper™ is only designed to be added to the cooling system. If the product is accidentally installed in the petrol tank, the tank should be removed and cleaned out by a professional mechanic.

I accidentally added the Liquid Copper™ into my engine oil, what should I do?
If the product is accidentally installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover where installed and drain the oil leaving the drain plug off. Then use an engine flush washing out the head giving 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, the vehicle needs to be towed to a professional mechanic for evaluation. This might include taking the engine apart to clean all of the internal parts.
