  It didn't solve my problem, the gasket had slightly seized, exhaust gas was passing into the water, it didn't solve it, I changed the gasket.

  The car was leaking oil into the water. I removed the thermostat, replaced the old water with new, poured in the liquid, and let it idle until the fan kicked in. Then I turned it off and let it cool completely. I did this 2-3 times. Afterwards, I reinstalled the thermostat. The sealant worked and so far, 2 months later, there is no oil in the water. Hopefully, it will remain this way, although these types of "repairs" are generally quite risky. I am also attaching 2 photos, before and after. The golden pieces shown in the after photo are not copper pieces as some say, they are synthetic material that patches the problematic area. If you decide to purchase it, it's generally a 50-50 chance whether it will work, and if it does work, it is very risky whether it will hold up. Only get it if you know what you're doing, otherwise you might make things worse than they were.

  I removed all the old coolant and added new, which the instructions do not mention because the old one had a lot of air inside and cannot function properly or may cause additional damage. This is the correct way. The car was cold, I started it and let it do a cold start for a minute, then I turned it off, poured the liquid, and went for a 15-kilometer ride, mostly uphill where the car struggled and reached high temperatures and made noises. Suddenly, the noises stopped, I changed gears, and the car is now working perfectly, it goes like a rocket.

  I was very skeptical about such products, I saw oil dripping under the multiple intake of my Vitara Santana 1997. I poured the whole bottle and after about 100 km, I didn't see a drop. I know it won't last forever, but it definitely saved me time to save money for repairs.

  It was tested on a motorcycle with a problem in the cylinder head gasket and it worked perfectly. The problem was quite serious as the engine had difficulty starting because it was bringing water into the cylinder when it was off. IMPORTANT.. the application of the product was done as follows: 1 removed the thermostat and drained the entire cooling system. 2 poured the product into a container with antifreeze. 3 poured the mixture into the engine's radiator and topped up with antifreeze. 4 let it idle for 15 minutes, let it cool down, and then idle again for 15 minutes, let it cool down and took it for a relaxed ride. 5 stars for the product for now, undoubtedly.

  It did the job fixing the problem completely, but unfortunately it didn't last long. The repair lasted 7,500km and 6 months. Cost was €49. Maybe it's worth trying once to see if it works for someone for a longer period of time.

  It did exactly the job it was supposed to do and saved me from the cost of repairing the head gasket on my Octavia 5... I would highly recommend it and the 30 euros I spent were worth it and more...
  Amazing product once again

  This specific one is for a 20-liter circuit, which means that cars need 236ml. We open the circuit to let some water out-Paraflo, and then we fill the liquid mixed inside Paraflo with at least 2 liters, as well as fill the expansion tank with the diluted liquid. After 3-4 days of use, if we don't see any difference, we open the entire circuit to let all the water out and then we put Paraflo with the mixed-diluted liquid again. The pure medication will circulate without diluting and will unclog our pipes

  I had a leak in the radiator of my refrigerator! Not only was it much more economical compared to visiting a repair shop, but I haven't had the problem again since then

  So far, I have driven 300 km and it has not raised the temperature or had any coolant losses. Every time I turned on the air conditioning, it would raise the temperature and overflow with water after a while. It is possible that the other two people who said it didn't work have a more serious problem. When I started the engine, I could hear water circulating inside the cabin, meaning there was air inside. Now I don't hear it. So far, it works perfectly. I will come back with an update.

  I bought the same one for my cousin's Fiat Panda. Unfortunately, as soon as he installed it, everything got blocked (he had to change the thermostat, radiator, and water pump). Repair cost was 250 €. I do not recommend it. In my case, I haven't had any issues so far, but it seems like it's not suitable for all cars. I give it 3 stars instead of 5 because it caused a problem with my cousin's car

  THE PRODUCT K-SEAL not only did not help at all with head gasket and engine block cracks, but it also clogged the small tubes in the intake, the coolant channels, etc., causing the temperature to rise just a few kilometers after starting. We washed the car several times, but it didn't achieve anything, absolutely no repair that it advertises to cure by 99%. Unfortunately, I do not recommend it, and the money-back guarantee is only on paper!

  Unfortunately, it didn't work. On the contrary, the car overheats and we had to flush the cooling system 5 times!
