Bar's Leaks Stop Leak will seal any leaks throughout the cooling system/radiator. It's best used as a preventative maintenance treatment. It functions to inhibit rust and scale, lubricates the seal on the water pump and most importantly seals internal and external leaks. BL340 is suitable for 6-8 cylinder engines. And all cooling systems 15-34 litres.

Bar's Leak is poured into the radiator turning the water a milky white. The Rhizex particles - the real "Stop Leaks"- find their way into cracks and porous metal. They dry out there and expand, forming in external leaks, a substance similar to putty. In internal leaks, especially where the heat is intense, these oil saturated particles form a resinous-like carbon that stops leaks successfully withstands compression.
