It’s part of life: older cars, trucks, vans, SUVs and even RVs can develop large leaks in their radiators and intake manifolds. If you’ve tried regular stop leak products you know they are not powerful enough to stop these larger leaks. That’s why Bar’s Leaks designed the Liquid Copper Block Seal Intake and Radiator Stop Leak. This one-step sealer was designed to quickly and safely stop these overwhelming leaks. What’s it do? Our formula permanently repairs larger leaks in radiators, intake manifolds and gaskets, heater cores, blocks, heads and freeze plugs. It contains an antifreeze-compatible sodium silicate liquid glass formula, so no draining of the cooling system is required. Not to mention, it will not harm the cooling system when used properly. Their stop leak products can’t get your show back on the road like Bar’s Leaks – that’s why we’ve been the most trusted stop leak brand since 1947. Make sure to watch Bobby and Caitlin in our handy how-to video so you can become a “three- Minute mechanic” and finally take control of that leak.
