Its part of life: older cars, trucks, vans, SUVs and even RVs can develop larger leaks in their radiators and intake manifolds. If youve tried regular stop leak products, you know they are not powerful enough to stop these larger leaks. If you visit the service center down the street, you know just how expensive it can be to repair an intake gasket leak through a mechanic. Isnt there a better way? There should be, which is why Bars Leaks designed the Liquid Copper Block Seal Intake & Radiator Stop Leak. This one-step sealer was designed to quickly and safely stop these overwhelming leaks. When youre experiencing a mild to moderate intake gasket seal leak, discover the fast, effective, inexpensive power of liquid copper. 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 youve been looking for is far more effective, easy to use, and less expensive than youve ever imagined. This is why Bars Leaks exists: To offer imminently usable, low-cost intake gasket seal and other products to auto owners who have no special experience or expertise.
