    In a 2009 Chevrolet Matiz with 800 cc and 120,000 kilometers, I had swollen hoses, dirty coolant, and I had to top it up regularly. The mechanic suggested changing the gasket at the corresponding cost. I did exactly what the instructions said, and now, after 2.5 months, the coolant is just like the first day. I was ready to proceed with the repair since other similar highly advertised products were quite expensive, and I tried this one with the aforementioned results. It worked for me without causing damage to the heating circuit, which was set to cold, and without removing the thermostat. The problem might have been small, and it might not work for a larger issue. Due to the low cost of testing, I recommend it before going to the mechanic.

    It does exactly what it promises for small leaks. I had just noticed the swollen collars and constantly dropping water level. When it was cold, you could hear the air in the system and the bubbles constantly. Doing exactly what the packaging says, everything stopped and a month later the coolant has the same level, the same color, the collars are soft and the bubbles are gone. Obviously, I recommend it for an old car that no one wants to deal with head gasket repairs and work costing 300+ euros.

  • I had swollen collars. It was throwing all the water in the overflow and then on the floor + bubbling. I did a repair of the head flange. Cap + body and continued exactly the same. Probably a crack. I put this and everything stopped immediately (I had tried another one before. It had very little improvement.) you put it in the refrigerator with deionized water so that the cooling circuit has no air bubbles at all. And have removed the thermostat.

    Resource in the cylinder head to the point where the car struggles to move forward due to water flooding. I opened the entire circuit, washed it with water pressure. I attached collars. I poured a liter of deionized water. I shook the bottle well, poured the entire contents into the radiator, filled the circuit with deionized water, let it idle for half an hour, let it cool down. The results are spectacular, it repaired it by 90%, the collars are not as tight, I just need a second bottle to completely solve the problem, due to extensive damage. Also, it did not clog my radiator. I wasted money on expensive repairs for nothing. I highly recommend it.

    Resource in the head gasket. Cylinder discharge in the cooling circuit. IT IS the ONLY thing that works !! Other expensive seals are useless. You need to Bye Bye the radiator's fridge. No matter which product you use...
