Dosage & Directions

Dosage
Use ½ bottle in a small cooling system, such as 4 cylinders engines.

Use 1 bottle for regular size systems such as most 4, 6, 8 and 10 cylinder engines.

For larger systems, use 1 bottle for every 12L of cooling system capacity.

Directions
Use with all types of antifreeze including conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) antifreeze. For most vehicles leaks stop instantly.

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

  1. Allow engine to cool. Make sure engine is cool enough so radiator cap can be safely removed.
  2. Shake well. Pour Liquid Aluminum™ directly into radiator. If using in a small cooling system, such as 4 cylinders with no air conditioning, install ½ of bottle.
    TIP: If direct access to radiator is not available, install in overflow tank.
  3. Fill radiator and overflow tank to proper level and reinstall radiator cap
  4. Turn Heater on hot and fan on high
  5. Drive/idle engine for 10 to 20 minutes
  6. Leave Rislone Liquid Aluminum™ in the cooling system for continued protection

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

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

Compatibility

Stop Leak

Xtreme Cool

Liquid Aluminium™ safely seals leaks in plastic, aluminum and metal radiators, heater cores, gaskets and welch plugs.

One of the few products to meet ASTM D6107 requirements for Stop Leak Additives used in Engine Coolants.

Xtreme Cool™ reduces the surface tension of coolant increasing the wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and leaks.

 

    Frequently Asked Questions

    Can Rislone® Liquid Aluminum™ be installed in existing antifreeze coolant?
    Yes, Liquid Aluminum™ is specifically designed to be directly added to the cooling system without having to flush out the antifreeze. It also can be used in water alone. But if using in water, it is recommended that another bottle of Liquid Aluminum™ be added to the system once antifreeze is installed.

    Will it work in the new extended life antifreeze?
    Yes, Liquid Aluminum works with all types of regular and extended life coolant including yellow, orange, pink, red, blue, purple and green silicate based & non-silicate based (OAT/HOAT) antifreeze.

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

    How long does it take to see results?
    We recommend you drive/idle the vehicle for 10 to 20 minutes. In most cases the leak will be sealed instantly, but others will require up to 20 minutes. If the leak is not sealed in 20 minutes, a second application may be required or mechanical repair may be needed.

    Will Liquid Aluminum™ plug my heater core?
    No, Rislone® Liquid Aluminum™ Cooling System Radiator Stop Leak product is part of the next generation stop leak line which is certified to be used in all cooling system types. It is guaranteed to safely and easily seal leaks in plastic, aluminum and metal (copper / steel) radiators, heater cores, gaskets and freeze plugs. 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.

    What are the dosage recommendations?
    Add one bottle for 5, 6, 8 and 10 cylinder engines. Use 1/2 bottle in 3 and 4 cylinder engines. One bottle treats cooling systems from 9.5 liters to 15 liters. Use 1/2 bottle for cooling systems from 5.5 liters to 9.4 liters. For larger systems use one bottle for every 12 liters of cooling system capacity. Small engines or other small systems use approximately 40 mL per liter of fluid capacity.

    How does Xtreme Cool™ make the vehicle run cooler?
    The Xtreme Cool™ additive in Liquid Aluminum™ reduces the surface tension of coolant increasing the wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and leaks.

    Can I install Liquid Aluminum in my overflow reservoir?
    Yes, if direct access to the radiator cap is not available, install in overflow/reservoir tank.

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

    The bottle froze before I was able to use it, what can I do?
    If the bottle did not break from freezing, just let the product thaw out, shake well, and use as normal.

    I accidently added the Liquid Aluminum into my engine oil, what should I do?
    If the product is accidently 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.

      Froths Milk in Seconds
      Color: Black
      Frother I had for a couple of years broke. Based on reviews I bought this. Love it being rechargable. The POWER! It froths milk in seconds. Also great for that after workout protein drink. Also is a little longer than my last frother so it works great with larger glasses.

      Best kitchen device!!
      Color: Black, Color: Black
      This frother is absolutely amazing such power behind it . Quality is just as amazing made very rugged. And I love the stand and the best thing about it is no more batteries to change now we just charge it up. I HIGHLY RECOMMEND this product to everyone and I will be buying more of these for gifts and more for our winter home also. You won’t be disappointed at all.

      Works as described
      Color: Black
      Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

      Very Powerful Frother!!
      Color: White
      I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds. I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges. Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

      Still The Best Frother Ever!
      Color: Black
      I love how it is easy to use, how it holds a charge, and how much power it has. I've only charged it once since I got it & I've been using it on a daily basis!!! Though it isn't a long time, I'm happy with it so far! I definitely will recommend it to anyone looking for a great frother. If you are looking for one, look no further! You won't be disappointed! I've read some comments where they found it to be too strong that their drink spilled everywhere. But for me I have not had any incident of spilling over. I have used it both for my coffee and my matcha tea and it worked great without any spilling over. You just have to start with the lowest power and ensure that you have a large enough container to have a room for your frothing. My sister tried to use it recently during her visit to make us matcha tea. However, she experienced spillage all over the cup, because she had used a small cup. Otherwise, she liked it very much and said she will get one when her battery operated one stops working... Another thing I like about the product was the customer service that I had received. When I got my first order which came quickly, it wasn't working after having charged it over 24 hours. It was not turning on at all. I returned it and ordered a replacement which I received within a day or two. This time after charging it for the recommended amount of time, I was a bit skeptical when I turned it on. However, I was pleasantly surprised that it worked like it was supposed to and it has been working ever since having charged it only once so far. I may come back and give an update depending on how it does after 6 months of use, so keep in tune... I don't know if there is a way to write a new entry as a follow up to the old entry, so I'm going to add my follow up comment over here. May 23, 2025 - I love my frother more than I can say in words. It's functionality has not changed a bit from the time I have purchased it. It charge lasts several weeks to few months before I charge it again and the power is still the same. Recently I decided to buy another one for my office use. I like the white color and so tried it but that one wouldn't even turn on. And then I got a gray one to have a different color. That one was much weaker than the black one I own. Then I replaced it with another gray one within few days. I tried it and it was exactly the same as the one I already replaced. So then I decided to go with a black one again hoping that it would be the same as the one I have. The black one did much better than the gray ones in the strength or power of the frother. However, it is weaker than the one I already have been using since last August. While I am not very happy with the quality being inconsistent in all of the ones I have tried including the recent pictures of the black one, I have decided to keep the black one because it is relatively better than the gray ones I tried. What I don't understand is why there is inconsistency in the quality of the same product by the same maker. I am beginning to wonder if the black one I purchased in Augusta last year was anomaly of a quality and a good way. Maybe I lucked out on my older black frother, but I'm unsure if quality is going to get better if I were to order another one. I have a sister who is a pro in making coffee drinks and she was the reason I had ordered this frother to begin with. She uses a battery operated one at this time and I have been thinking about getting her one like mine. While I am still skeptical, I am going to give it a shot and order her one sometime soon. If it doesn't work, I guess we will return it back. But one thing that I am grateful is that I have been able to return every one of those that I have tried recently with no issues. I hope that I don't have to return my most recent purchase in black. I was not even able to review the new purchase because of the item being the same color which is crazy.
