Review on 🔧 Effective 16.9 oz Gray Bar's Leaks 1186 Liquid Aluminum Stop Leak for Superior Performance by Peter Joseph

I used half a bottle in a 2002 Altima 3.5 and the leak stopped completely in about a week. The leak was so bad that I had to fill up the tank every few days. Important Tips: 1- Before using this product, make sure the engine is cold and check the color of the coolant in the radiator. The reason some users complain about this product clogging the core of their heater is that the antifreeze is dirty in the first place. Green = Clean / Maroon = Dirty. Mixing particles in the coolant with the wand causes problems. 2 - Use cheap turkey lube to pump enough coolant out of the radiator before adding a bar to keep it from overflowing. 3 - For some users, the bar works right away, but don't worry if it doesn't. As mentioned above, the leak in my car stopped within a week. Good luck everyone!
