Bar's Leaks 1177 Radiator Stop Leak Tablets, 1.76oz

This stuff works miracles. Bar's has a solid rep, and this is no different. Awesome.

I’ve used this product for along time on many different vehicles, works good, hard to find in stores anymore.

I have a National Corvette Restorer Society Top Flight award winning Corvette. I was not able to purchase another water pump with the correct part number, date codes, etc. My alternative was to install a non conforming water pump or try Bar's Stop Leak. It worked great. No leaks and I retained my original water pump

works well on a small leak, I use 1 in cooling system to stop any small leaks

Stopped the leak

Actually worked it my kids car and mine. I used it to seal the seeping between the radiator core and plastic tank. It takes a couple weeks to completely seal. Its a good temporary fix until you can replace radiator with a new one. Its an inexpensive temporary fix and for price its a good deal.

The item itself seems to have temporarily fixed the problem I was having. I was however, less than pleased that it was open in the Amazon package and one piece short; as it had crumbled and made a mess all over the rest of my items. Overall good product though.

Didn’t work
