Stop leak works by circulating through the cooling system and sealing any small holes or cracks in the radiator, hoses, or other components. It can be effective in stopping small leaks, but it may not be able to handle larger leaks or leaks caused by severe damage.
It's also important to use stop leak according to the manufacturer's instructions and to avoid overusing it. Excessive use of stop leak can clog the cooling system and cause overheating or other problems.
If you're experiencing a coolant leak, it's best to have the vehicle inspected by a qualified mechanic to determine the cause of the leak and have it repaired properly. Stop leak can be a helpful temporary solution, but it should not be used as a substitute for proper repairs.
