FAQ:

Q: What is the liquid copper block seal intake&radiator stop leak?

A: There should be, which is why Bar’s 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 you’re experiencing a mild to moderate intake gasket seal leak, discover the fast, effective, inexpensive power of liquid copper. What does it do?

Q: Will bar’s leak 1109 block seal liquid copper work in a DeVille?

A: I poured a bottle of Bar’s Leak 1109 Block Seal Liquid Copper in a 2002 Deville and a 2005 Deville. Both are running cooler [due to lack of coolant leaks] and the Coolant Overflow Reservoirs remain at their ‘full’ levels.

A: When you’re 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.

Q: How do you use bar’s leaks liquid copper?

A: Shake well. Pour Bar’s Leaks Liquid Copper directly into radiator. If using in a small cooling system including all 3 and 4 cylinder engines, use 1/2 bottle. TIP: If direct access to radiator is not available and if overflow tank is pressurized, you can install in tank. Fill radiator and overflow tank to proper level and reinstall radiator cap.
