Frequently Asked Questions
Can Bar’s Leaks Liquid Aluminum be installed in existing antifreeze coolant?
Yes, Liquid Aluminum is specifically designed to be directly added to the cooling system without having to flush out the antifreeze. It also can be used in water alone. But if using in water, it is recommended that another bottle of Liquid Aluminum be added to the system once antifreeze is installed.
Will it work in the new extended life antifreeze?
Yes, Liquid Aluminum works with all types of coolant including yellow, orange, pink, red, blue and green silicate based and non-silicate based OAT/HOAT antifreeze and/or water.
How long does it take to see results?
We recommend you drive/idle the vehicle for 10 to 20 minutes. In most cases the leak will be sealed instantly, but others will require up to 20 minutes. If the leak is not sealed in 20 minutes, a second application may be required or mechanical repair may be needed.
What's in it?
- The two key ingredients in this product are Liquid Aluminum and Xtreme Cool.
- Next-generation stop leak line that not only seals leaks, but also conditions the system.
