Same tablets as used by many OEM auto and truck manufacturers around the world. Bars Leaks Radiator Stop Leak is designed to enhance the use of antifreeze or can also be used in water.

I bought these Bars Leaks radiator tablets to tackle a small leak in my car's radiator. After just a couple of days, I noticed a significant reduction in leaks. The pack of 7 is handy for multiple uses, too! Definitely recommend for DIY repairs.

Decent Fix, But Takes Time
These radiator stop leak tablets from Bars Leaks did help slow down the leak in my older vehicle, but it took a bit longer than I expected. I followed the instructions carefully, but I still had to wait a whole week before seeing results. Packaging was a bit torn when it arrived, but nothing major.

Didn’t Solve My Problem
Unfortunately, these radiator stop leak tablets didn't work for me. I followed the directions, but my leak persisted. I really wanted them to work, especially since so many people recommended them. I guess it's just not effective on larger leaks.
