HDC Bar's Products Radiator Sealer

Our product engineers created these Bar’s Leaks Radiator Stop Leak Tablets to repair radiator leaks from within so you can get back on the road in no time. These tablets might not be able to surf the web, but they are definitely more powerful than you think. But what our radiator leak repair tablets offer in effectiveness, they don’t sacrifice in usability or affordability. In fact, you need no special automotive expertise to apply our tablets to repair radiator leaks. Our Radiator Stop Leak Tablets inhibit the formation of rust and scale, neutralize pH imbalance, control electrolysis, lubricate and seal internal, external and coolant-to-oil leaks. Imagine getting that range of effectiveness in a product you can buy off the shelf rather than through service only a mechanic can provide. In fact, this is the same product that’s been used right on the assembly line by OEM automakers around the world for 30+ Years. This solution is the result of careful research and testing on the part of our team of top-flight chemical engineers. They work each day to improve existing products like our radiator leak repair tablets, as well as to develop new products to keep up with the latest in automotive innovations and technologies.
