PURPOSE OF A COOLING SYSTEM
Your engine creates up to 2750 degrees C of heat within the combustion chamber. Enough heat to melt the entire engine in less than 30 minutes! Approximately 1/3 of gasoline’s energy is converted into usable power to propel the vehicle, 1/3 of the energy is dissipated out through the exhaust system, and the remaining 1/3 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!

Frequently Asked Questions
Additional Product Info
SDS / Technical Info
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 ALL types of traditional or extended life coolant including yellow, orange, pink, red, blue, purple and green silicate based & non-silicate based (OAT/HOAT) 50-50 mix antifreeze, and/or water.
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 fibers, 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 fibers catch on the side of the leak or hole eventually bridging the entire hole. The fibers now act as a sieve trapping more fibers, 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, a second application may be required or mechanical repair may be needed.
What are the dosage recommendations?
One bottle treats cooling systems from 11 liters to 23 liters. Use 1/2 bottle for cooling systems from 7 liters to 10.9 liters. For larger systems use one bottle for every 23 liters of cooling system capacity. Small engines or other small systems use approximately 25 mL per liter of fluid capacity.
Will Liquid Copper™ plug my heater core?
No, Liquid Copper™ will not plug the 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 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.
Rislone® Liquid Copper™ Block Seal Intake & Radiator Stop Leak seals larger leaks regular stop leaks won’t. One step formula permanently repairs coolant loss problems on cars, trucks, vans, SUV’s and RV’s. Antifreeze compatible sodium silicate liquid glass penetrates large and small leaks in plastic, aluminum and cast iron heads, blocks, intake manifold & gaskets, freeze plugs, heater cores and radiators.

Additional Product Info
SDS / Technical Info
Can Rislone Radiator Stop Leak Tablets be installed in existing antifreeze?
Yes, this product is specifically designed to be directly added to the cooling system without having to flush out the antifreeze.
Will Rislone Radiator Stop Leak Tablets work in extended life antifreeze?
Yes, Rislone Radiator Stop Leak Tablets works with all types and colors of antifreeze coolant including conventional, extended life, waterless and straight water.
How does Rislone Radiator Stop Leak Tablets work?
Rislone Radiator Stop Leak Tablets will seal external, internal and coolant to oil leaks. Once installed, the Rislone Radiator Stop Leak Tablets particles shrink up to 15 percent. On an external leak, the tiny particles flow to the point of the leak. They then collect at the outside of the seepage and build inward. Internal leaks, the Rislone Radiator Stop Leak Tablets particles will burn when subjected to the 2750° C heat of the combustion chamber to seal seepage and small cracks. On coolant to oil leaks, where coolant can seep into the crankcase contaminating the oil, the tiny Rislone Radiator Stop Leak Tablets particles will seal the pores in cast iron and aluminum preventing seepage.
How long does it take for the Rislone Radiator Stop Leak Tablets to work?
We recommend you drive/idle vehicle for 15 to 20 minutes. In most cases the leak will be sealed within this amount of time. If the leak is not sealed, a second application may be required.
Will Rislone Radiator Stop Leak Tablets plug my heater core?
No, the tiny particles will pass through a 24-gauge mesh screen which is the specification for the BIG 3 car/truck manufacturers. They say that any product installed in the cooling system must pass through this screen. Rislone Radiator Stop Leak Tablets are one of only a few stop leak products to pass this test and to be approved by the vehicle manufacturers. Note: If using Rislone Radiator Stop Leak Tablets 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.
What if I don’t have a radiator cap?
If the vehicle does not have a regular radiator cap, remove the top hose where it attached to radiator and insert tablets in hose and then reinstall hose.
How do I pre-dissolve tablets?
Just add tablets to warm tap water.

Frequently Asked Questions
Additional Product Info
SDS / Technical Info
Can Rislone be installed in existing antifreeze?
Yes, this product is specifically designed to be directly added to the cooling system with out having to flush out the antifreeze.
Will Rislone work in the new extended life antifreeze?
Yes, Rislone is compatible with both conventional silicate-based and extended life (OAT/HOAT) antifreeze, all types and colours. Can also be used in straight water.
How does Rislone work?
Rislone will seal external, internal and coolant to oil leaks. Once installed, the Rislone particles shrink up to 15 percent. On an external leak, the tiny particles flow to the point of the leak. They then collect at the outside of the seepage and build inward. Internal leaks, the Bars Leaks particles will burn when subjected to the 2,500°C degree heat of the combustion chamber to seal head gasket seepage and small cracks. On coolant to oil leaks, where coolant can seep into the crankcase contaminating the oil, the tiny Rislone particles will seal the pores in cast iron and aluminum preventing seepage.
How long does it take for the Rislone to work?
We recommend you drive / idle vehicle for 15 to 30 minutes. In most cases the leak will be sealed within this amount of time. If the leak is not sealed, a second application maybe required.
Will Rislone plug my heater core?
No, the tiny particles will pass through a 24-gauge mesh screen which is the spec for the BIG 3 car/truck manufacturers. They say that any product installed in the cooling system must pass through this screen. Rislone is the only stop leak to pass this test and to be approved by the vehicle manufacturers. 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.
How do I pre-dissolve pellets?
The easiest way is to pour the liquid from bottle into the radiator and then add hot water to the pellets in the bottle. Shake bottle for a few minutes to dissolve pellets.
What are the dosage recommendations?
Use 1 bottle for 6, 8 and 10 cylinder gas or diesel engines. For 3, 4 and 5 cylinder engines, use ½ of liquid and pellets. One bottle treats systems up to 15 liters. For larger systems use one bottle for every 12 liters of cooling system capacity.
I accidentally added the Rislone Heavy Duty Stop Leak to my overflow / reservoir what should I do?
It is our recommendation to drain and flush the overflow reservoir then install the product directly into the radiator.
I accidentally added the Rislone Pelletized Stop Leak into my engine oil, what should I do?
Rislone Pelletized Stop Leak 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.
Rislone® Original Rhizex® Pelletized Formula Heavy Duty Stop Leak seals internal, external and coolant-to-oil leaks. It is specially formulated to seal larger leaks better than other stop leak products. Works safely and effectively on plastic, aluminum and metal radiators, heater cores, blocks, heads, gaskets and freeze plugs.

Frequently Asked Questions
Additional Product Info
SDS / Technical Info
When using Rislone Hy-per Cool Super Coolant with straight water, do I have to worry about corrosion problems?
No, Super Coolant is formulated for use with straight water and will provide maximum corrosion protection.
Is Rislone Hy-per Cool Super Coolant compatible with all types of antifreeze?
Super Coolant is compatible with all types and colors of glycol/water-based coolants including yellow, orange, pink, red, purple, blue, green regular silicate & non-silicate and extended life antifreeze. It also works great in systems containing only water. Because Super Coolant is water based, do not use with waterless antifreeze.
If I increase the percentage of water in the system can I get even better cooling when I use Rislone Hy-per Cool Super Coolant?
Yes, you can get improved cooling and lower temperatures by adding additional water to your system. Keep in mind that you will not maintain the same freeze protection when you increase the percentage of water in the system. But if you live in a warm climate area and you change the mix to around 35% Antifreeze and 65% water you will still receive freeze protection down to -18°C. For most racing applications it is beneficial, and many times required to run 100% water in the cooling system and this with Super Coolant gives you the best cooling heat transfer.
Can I use the Rislone Hy-per Cool Super Coolant in a Diesel Engine?
Yes, you can. It will provide the same temperature reduction performance and corrosion protection in a diesel engine as petrol. Adjust dosage as needed for larger cooling system size.
How much Rislone Hy-per Cool Super Coolant do I install?
Use one 473 mL bottle of Super Coolant, part number 41300, to treat 11.5 to 19 liter systems. For larger and smaller systems add 30 mL per liter of capacity.
How do I use Rislone Hy-per Cool Super Coolant?
Never remove radiator cap when engine is hot. With engine off and cool, remove radiator cap and add contents of bottle. Reinstall cap and drive vehicle normally.
What if I don’t have direct access to the radiator?
If you do not have direct access to your radiator, Super Coolant can be installed in the overflow tank. It will take 4 to 5 heating and cooling cycles for product to fully enter the system using this method.
What if my cooling system is already full?
Usually the easiest way is removing some fluid from the system by using a coolant tester or old turkey baster to suck some fluid out. You can also open the drain on the bottom of radiator to remove enough fluid to add Super Coolant.
How often should I add Super Coolant to system?
For best results and protection, we recommend treating the cooling system once per year, and every time changing coolant.
How much of a cooling system temperature drop can I expect when using Super Coolant?
In systems running a 50/50 antifreeze water blend you can expect a 4 to 6 degree Celsius cooling temperature reduction. If using straight water, you can get up to a 17° C reduction. Cooling system temperature minimum is controlled by the thermostat, so if the vehicle is already running at the minimum, you will not see any reduction below that. But when towing, under load, racing or working the cooling system harder, this is where the reduction will be shown.
Why is reduced cylinder head temperature (CHT) so beneficial?
The hottest area of the cooling system, and the engine itself, is around the combustion chamber and exhaust port. The metal is extremely hot and coolant is so hot that it can boil and create air bubbles which insulate the coolant from the metal, causing even more heat. Super Coolant reduces the temperature in this area up to 41°C which allows the engine to run more efficiently, reduces potential spark knock, allows timing to be advanced, and creates more power and torque.
What are some of the most common causes of overheating?
Scale & deposits in the cooling system from hard water, and glycol dropout from old antifreeze can build up on the interior surfaces, and even plug coolant passages. Even a small amount of scale 1.5 mm thick can reduce heat transfer by 40%. Other causes include performance vehicles with larger engines which don’t have a large enough cooling system, towing over the rating of the vehicle, and mechanical problems like a bad water pump impellor.
Can Rislone Hy-per Cool Super Coolant be used on the race track?
Yes, one of the number one uses for Super Coolant is in racing vehicles, including drag racing, oval track, off road, monster trucks and many other motorsports events. Many racing series and tracks require that no glycol is put into the cooling system because once that leaks on the track it becomes very slippery and dangerous. Super Coolant does not contain glycol.
Do I need to flush cooling system before using?
No, the cooling system does not need to be flushed before using. But if the system is dirty you will receive the maximum benefit of the product by completely cleaning the system first.
Can it be used with extended life coolants?
Yes, Super Coolant works equally well with extended life coolants.
Rislone® Hy-per Cool™ Super Coolant contains very high cloud point surfactants designed to provide maximum wetting (coolant surface tension reduction) at normal and high cooling system operating temperatures. This supercharged coolant mixture eliminates bubbles, resulting in improved heat transfer to dissipate heat more efficiently in the entire cooling system. Real world and laboratory testing shows reduced engine temperatures by up to 17°C helping to prevent overheating. Super Coolant lubricates and protects the water pump, and helps prevent corrosion, erosion and electrolysis of all parts of the cooling system, including aluminum, plastics, rubber and more. Super Coolant works with all types and colors of glycol/water based coolants including yellow, orange, pink, red, purple, blue, green regular silicate & non-silicate and extended life antifreeze. It also works great in systems containing only water.
Provides extra protection against higher engine temperatures. Up to 41°C lower cylinder head temperatures (CHT) enhance engine efficiency, proving better fuel economy, power and performance.
Use in gasoline classic cars, hot rods, trucks, RV’s, motorcycles, automotive, heavy duty, diesel, powersports ATV, off road, racing, towing and most anything else with a cooling system.
Racing approved and safe to use from drag strips to the oval track. Contains no glycol. Provides no antifreeze protection. Always check for freeze protection if needed.

Frequently Asked Questions
Additional Product Info
SDS / Technical Info
How long does it take to start working?
Rislone Engine Repair starts working the minute you install and start driving the vehicle. You will usually see results in about 150 km miles or two (2) days of driving.
If first application does not completely stop my leak, may I add another bottle?
Yes, in engines with seriously damaged components, a second treatment may be required. In this case, it is suggested that the oil and filter be changed, and a second application of Engine Repair be added.
If I install more than the recommend amount, will it work faster or better?
No, we have formulated our product to work best at the suggested dosage amount.
What are the dosage recommendations?
One 500 mL bottle of 34110 is designed to treat 3.5 to 5.5 liters of oil, which is the normal size for most vehicles. On smaller systems from 2 to 3.4 liters, only use half bottle, pouring equal amounts from each side. For larger systems use one bottle for every 5 liters of capacity.
Can I add to existing oil?
Yes, remove engine dipstick and check oil level. If oil is low, remove oil cap and install entire contents of the two chamber bottle. Do NOT overfill. Top off with manufacturers recommended engine oil as needed. Reinstall dipstick and oil cap. Drive/idle engine for 10-15 minutes.
Will Rislone Engine Oil Stop Leak work in synthetic oil?
Yes, Rislone Engine Repair is compatible with ALL types of engine oils, including petroleum, synthetic and high-mileage formulas
Isn’t Engine Oil Enough?
Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and is a method of removing contaminants. As lubricants degrade, their properties change, leading to increased friction and wear. Over time the natural wear that occurs inside the engine causes reduced oil pressure, loss of compression (power loss), lower fuel mileage, oil consumption (leaks & smoking) and noise (knocking & ticking).
Will Rislone Engine Repair clog my oil filter?
No, Rislone Engine Repair does not contain any sticky substances that would clog or damage your oil filter. It works chemically to stop leaks in gaskets and seals.
Rislone High Mileage / Kilometre Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals. For most vehicles, this is your last chance before paying an expensive repair bill or replacing the vehicle. Engine Repair can be used to top off the existing oil when low, or add a bottle when changing the oil and filter.

The common element between all of the engine components is the oil. Oil is the life-blood of the engine and is pumped under pressure to all the moving parts. The two main parts needing oil for lubrication are the bearings and pistons. As the engine ages and gains more kilometres, the oil alone can’t do the job. Internally, parts don’t fit as tightly as they originally did, which causes noise and loss of power. Bearings wear down, seals leak, lifters tick, blow-by passes around tired rings, and power is lost. When installed, Engine Repair helps to stop and prevent these problems and will also extend the useful life of your engine. Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and be a method of removing contaminants.

WHAT IS AN ENGINE?
There are two basic types of engines:
Gasoline Engine – most cars’ & light duty trucks – The most popular engine runs on a mixture of petrol and air. The air & fuel is compressed (squeezed) and then ignited by a spark to move the piston, which in turn allows the vehicle to move.
Diesel Fuel Engine – some cars’ & most heavy duty trucks – The second most popular engine runs on a mixture of diesel fuel and air. Instead of spark, it uses the high temperature caused by extreme compression of the air & fuel mixture to move the piston.
Works on ALL Engines
Gas, Diesel, Hybrid and Turbo
Engine Components
Automotive engines are a combination of mechanical, hydraulic and electric parts.
Mechanical
Many mechanical parts are required to operate an engine. Some of the more important parts are the oil pump, crankshaft, bearings, seals, piston rings, lifters and valves.
Hydraulic
The hydraulic system uses the oil pump to create pressure which lubricates internal engine parts and helps to operate the lifters and cam phasers.

Can a single product handle both oil leaks and excessive oil burning? Yes it can.
This product fixes both problems. There could be two possible reasons as to why your vehicle is burning engine oil. It may have an oil leak or you it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So, when the fuel ignites the oil does as well, and then expels it out as exhaust. Then, suddenly, you’re dealing with an oil burning problem.
The good news is that with a single application of Rislone Oil Seal, those problems will be gone.

Will Rislone® Oil Seal™ Engine Oil Burning & Leak Repair work in all types of oil?
Yes. This premium quality synthetic blend works with all types of motor/engine oil including regular
petroleum, high mileage, synthetic blends and fully synthetic formulas.
How does Rislone Oil Seal Engine Oil Burning & Leak Repair work?
This product works in four ways to help solve most oil consumption issues.
1) A specially-engineered seal rejuvenating additive restores seal size, flexibility and elasticity lost
due to engine heat, age and high mileage.
2) An advanced seal polymer additive package works by building a polymeric film around the seal
to help prevent excess oil from bypassing the seal during normal engine operation.
3) A superior detergent and cleaning package can dissolve gunk and carbon on stuck piston oil
rings freeing them up so they can work properly.
4) Synthetic polymers can fill in small scratches and wear marks preventing oil from passing and
being burned.

ENGINE OIL BURNING
There could be two possible reasons as to why your vehicle is burning engine oil. It may have an oil leak or you it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So when the fuel ignites the oil does as well, and then expels it out as exhaust.
ENGINE OIL LEAKS
Depending on the severity of the leak, the first thing you will notice is dark brown spots underneath the front of the vehicle. The oil level will also decrease and if left long enough the oil pressure will drop and/or oil light will come on. A few other things can cause an oil leak that are not the fault of the seal or gasket. If the oil level is too high (filled over the full mark) or the PCV (Positive Crankcase Ventilation) system is not functioning correctly, leaks can occur.
Premium Seal Restorer Additives
Synthetic polymers combined with premium seal restoring additives work together better than all other regular treatment products to create a long lasting repair. These polymers also fill in small scratches and wear marks preventing oil from passing and being burned.
Seal Restorer:
Restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.
Seal Polymer:
Chemical polymers work where other stop leaks fail to seal leaks that is caused by normal engine wear. This includes grooves worn in the crankshaft seal mating surface. The polymer forms a film between the seal and the crankshaft, preventing leaks.
Have you noticed oil leaking from your car? That might be due to worn or dried seals. There’s no need to worry or spend your money on a costly repair bill, however. Our Rislone Rear Main Seal Repair quickly and safely restores those seals so you can get back on the road and back to your life.
Most rear main seal leaks are caused by a combination of normal wear in the crankshaft and seal and the drying, hardening and shrinking of the main seal. Rislone Rear Main Seal Repair restores the seal to like-new condition and also contains additives to stop leaks in severely worn seals and crankshafts. Not to mention, it works with ALL gasoline and diesel engines using conventional, high kilometer and synthetic oil.

Frequently Asked Questions
Additional Product Info
SDS / Technical Info
What is a rear main seal?
The simple answer is: A seal that fits around the rear of the crankshaft to prevent oil leakage. The more in depth answer is: A rear main seal, also known as a main seal or rear main bearing seal is located between the engine and transmission. The crankshaft (the internal engine part that the pistons are connected to) sticks out of the rear of the engine, and the flywheel & transmission bolt to this crankshaft. The engine oil lubricates the crankshaft, pistons and other internal parts of the engine. The rear main seal is inserted into the back of the block and fits snugly around the rear of the crankshaft and keeps the engine oil from escaping.
What are the symptoms of a rear main seal leak?
Depending on the severity of the leak the first thing you may notice is the oil level going down. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage. While looking under the vehicle around the area where the engine and transmission connect, you will find oil dripping, or an oil residue with dirt caked on this part of the vehicle, most noticeably under the oil pan and the front of the transmission. In some transmissions, it will actually be the oil leaking out of the front of the transmission. In some manual transmission vehicles, you may also notice some slipping of the clutch, which can occur with a leaking rear main seal.
What causes the rear seal to leak?
The most common cause of rear seal leaks is age and/or high kilometre. The seal can also leak due to the vehicle being stored for an extended period of time, or from running the engine low on oil. This causes drying and hardening of the seal leading to shrinking, cracking and tearing of the rear main seal.
What other factors can contribute to a rear main seal leak?
A few things can cause a rear main seal leak to worsen, which are not the fault of the seal itself. If the oil level is two high (filled over the full mark) or the PVC (Positive Crankcase Ventilation) system is not functioning correctly, leaks can occur. The PVC system prevents pressure from building up inside the engine and if it fails, the pressure will cause the oil to leak out. It is a good idea to clean or replace the PCV valve regularly to prevent this problem.
How do you replace a rear main seal?
For most rear wheel drive vehicles the transmission is removed to replace the seal. On front wheel drive vehicles, it is usually easiest to remove the engine to gain access to replacing the seal. Either way, this is an expensive procedure.
What else can be done to stop a leaking rear seal other than replacement?
Rislone Rear Main Seal Repair is one of the only products of its kind on the market speci
