A lot depends on the type of leak you have—whether it’s coming from a hose, the radiator, or another part of the cooling system. In my case, I used it and it stopped the leak. I would say it may work well if the leak is small or minor. If you have a major leak, your results may be different. For the price, it was worth trying and it helped solve my problem. ⭐⭐⭐⭐⭐ ### ⭐⭐⭐⭐⭐ ممتاز *by on Reviewed in Saudi Arabia 11 February 2022* جيد ### ⭐⭐⭐⭐⭐ SI ME FUNCIONO! *by on Reviewed in Mexico 20 June 2024* SI ME FUNCIONO !!
