What does 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. The intake gasket seal you’ve been looking for is far more effective, easy to use, and less expensive than you’ve ever imagined. This is why Bar’s Leaks exists: to offer usable, low-cost intake gasket seal and other products to auto owners who have no special experience or expertise. We’ve been doing this for over 70 years, so we know a thing or two about chemical repairs.

Bar's Leaks

by Michael M. - Columbus, OH on Bar's Leaks

I want to leave feedback... I used the Bar’s Leaks Copper Block Seal on my 2000 Caddy STS. Before I used this stuff my car could only run for about a mile before it started to overheat. I tried a couple of other fixes, the ceramic, the fiber which both made you flush your cooling system before you even added the crap. Then I used your Copper Block Seal and it worked. I paid over $150 for a treatment of the ceramic stuff and it didn't do anything, the fiber ceramic didn't do anything either. They were both a waste of money. Your Bar’s Leaks Liquid Copper Block Seal is the best s**t I have EVER used.

by E. C. - Southern Windows & Doors on Bar's Leaks

I've used Bar's Leak several times over the years, but you have so many products available now that I really didn't know what to use. Thank you for recommending Liquid Copper Block Seal for the intake manifold leak on our 1999 GMC. It seemed to work immediately and hasn't leaked a drop. Good products, good website and great advice. Thanks again for your help.

by P. B. - Sunnyvale, CA on Bar's Leaks

I had a head gasket leak that was requiring me to replace about a gallon of coolant every 2 days. After using only 1/2 of a container of your Liquid Copper Block Seal [because disconnecting the return line to the radiator, I could only pour in that amount], the problem vanished. At some point I do need to repair the head gasket, but your product has bought me some valuable time.
