Rislone Block Seal Head Gasket Sealant is scientifically formulated to permanently seal coolant leaks that are the cause of most overheating problems. For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This product contains a blend of aramid and refractory fibers giving the strength of a bullet proof vest and the heat resistance of fire-proof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond forming a hard permanent ceramic type seal. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Works effectively on cast iron or aluminum blocks & heads. Detailed instructions on back booklet label take you through each step of using the product.

• World’s Most Trusted Stop Leak Brand Since 1921 
• Stops All Coolant Leaks
• Seals Block Leaks, Blown Head Gaskets, Cracked Heads and Other Hard to Stop Coolant Leaks
• Dual Action 2 Part Formula—Twice the performance
  LIQUID CERAMIC
  Liquid penetrates large and small leaks to form a seal actually harder than the original head gasket.
  REINFORCED FIBERS
  Fiber additives lock together with liquid to increase strength and promote a permanent seal.
• Only Add to Radiator After Removing Antifreeze

Overheating can be caused by a blown head gasket, cracked head or leaking block. Rislone Block Seal Head Gasket Sealant eliminates this problem. In addition, overheating can be caused by a stuck thermostat, bad water pump or defective radiator cap. If at any time the engine overheats, turn vehicle off and allow engine to cool. Make sure these cooling system parts are in good working order before using Rislone Block Seal Head Gasket Sealant. When one of these parts fails, it can cause the head gasket to fail.

WARNING:
Head Gasket Sealant is NOT COMPATIBLE with antifreeze and must only be added to the cooling system after ALL ANTIFREEZE has been flushed and removed.

DANGER:
Opening the cooling system while engine is hot or running may cause severe burns.

DISPOSAL:
Observe local laws & regulations. Where permitted, dispose of in sanitary sewer system. Never pour on the ground or in a storm sewer system.

NOTE:
Protect from freezing.

INSTRUCTIONS:

1. Engine must be cool enough to safely open the radiator cap. (This could take 30 minutes or longer). Drain and completely flush antifreeze from cooling system and overflow tank. Using a flush “T” with garden hose works best. If cooling system is dirty, use a good quality flush following manufacturer’s instructions. ALL antifreeze must be removed or clogging may occur.
2. Shake well, Mix Head Gasket Sealant in a bucket or container with approximately 3 litres of warm water. Pour this mixture directly into the radiator. If using in a small cooling system, including all 4 cylinder engines, mix ½ bottle of the Head Gasket Sealant with the warm water.
   TIP: If you do not have access to your radiator and vehicle has a pressurized reservoir, then product can be added to reservoir. If not then remove top hose where it connects to the top of radiator and install product in hose. Reattach and tighten clamp.
3. Fill cooling system with water and reinstall radiator cap.
4. Start engine, turn heater on hot and fan on high.
5. Run engine for 10 minutes or until thermostat opens.
6. Turn vehicle off and allow engine to cool. Allow enough time so it is safe to open cap.
7. Top off (fill up) cooling system with water and reinstall radiator cap.
8. Run engine at idle until normal operating temperature is reached. Continue running engine at idle for 15 minutes.
9. Turn vehicle off and allow 45 minutes to cool.
10. Top off cooling system with water as needed and reinstall radiator cap.
11. Run engine at idle until normal operating temperature is reached. Continue running engine, but at high idle (approximately 1200 RPM’s for vehicles with a tachometer) for 20 minutes.
12. Turn vehicle off and allow engine to cool for 1 hour.
    TIP: For vehicles with intermittent or very minor leaks, it is recommended to follow step 12 by idling vehicle for one hour.
13. Remove radiator cap and drain system.
14. Leave drain open and radiator cap off for 12 to 24 hours. If temperature is below freezing, vehicle must either be kept heated or immediately go to step 15.
15. Flush entire cooling system and refill with manufacturer’s recommended antifreeze / water mixture.

DOSAGE:
One bottle treats cooling systems from 7.5 to 19 litres. Use 1/2 bottle for cooling systems from 4 to 7.5 litres.
For larger systems, use 1 bottle for every 19 litres of cooling system capacity.

Rislone Block Seal Head Gasket Fix is the easiest solution to stop head gasket coolant leaks. No draining of the cooling system is required. One step formulation contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles which penetrate gaps and cracks then harden to permanently stop leaks. This works because of the extreme heat inside the combustion chamber (2750°C) that acts 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 gasoline and diesel engines. Heavy duty formula works on aluminum and cast iron heads & blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak. This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs. Use 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.

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. Gas 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!

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.  Fiber additives lock together with liquid to increase strength and promote a permanent seal.  It will not harm the cooling system when used properly, no draining is required.  Use 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.

Rislone® High Kilometre / Mileage Compression Repair with Ring Seal is a concentrated proprietary blend of high-shear and premium polymers developed for higher mileage engines that are suffering from decreased or uneven compression. Low compression can be caused by normal engine wear and decreased sealing between the piston rings and cylinder walls. The non-dispersant olefin copolymers fill scratches & grooves in cylinder walls to increase and stabilize compression in all cylinders. Compression Repair renews worn engines, rebuilds compression, restores lost power and repairs engine blow-by. In addition, Compression Repair helps vehicles pass emission tests.

Some signs of decreased compression include loss of power, poor fuel economy, oil consumption, blue smoke from exhaust, plug fouling and engine noise or vibration.

The Viscosity Improver (VI) is designed specifically to provide an optimum balance of shear stability and thickening efficiency required in old and modern engines. This performance additive meets the most severe passenger car and truck engine requirements.

Product works by freeing sticky rings and filling gaps & scratches in cylinder walls, eliminating blow-by and compression loss while also reducing friction and wear. Blow-by is usually caused by gaps in internal engine parts resulting from excess wear.

Rislone Compression Repair with Ring Seal does not contain any harmful lead or other metals that could damage the inside of your engine or be burned and contaminate emissions components and the environment.

Works on gasoline and diesel engines with conventional, high kilometre and synthetic engine oils.

INSTRUCTIONS:
Add entire bottle of COMPRESSION REPAIR WITH RING SEAL to engine crankcase at or between oil changes. Do not overfill. Results will either be immediate or noticeable within a few days of driving. Install Compression Repair every 10 000 km or with every oil change.

DOSAGE:
One bottle treats 4 to 6 litres of oil. For larger engines, use one bottle for every 5 litres of capacity. On 4-Stroke ATV, Motorcycle and small engines, including wet clutch applications, use approximately 100 mL per litre of oil capacity.

Most rear main seal leaks are caused by a combination of normal wear in the crankshaft & seal and the drying, hardening and shrinking of the main seal. Rislone Heavy Duty Rear Main Seal Repair restores the seal to like new condition and also contains additives to stop leaks in severely worn seals and crankshafts.  Compatible with all petroleum based engines oils including high-mileage / kilometer and synthetic.  Works with ALL vehicle types including gasoline, diesel and turbocharged.

Specifically designed to seal rear main leaks, but also works better than a conventional stop leak on all other leaks.  This includes the timing cover seal, cam seals, O-Rings and other gaskets.

For many vehicles this is your last chance before paying an expensive repair bill.  To replace the rear main seal on most front wheel drive cars, the engine has to be removed and on rear wheel drive vehicles, the transmission is removed
