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.

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

I'm shocked that a $4 fix like this works. I had a substantial coolant leak on my Ram 1500 and two tabs of this seems to have sealed it right up. Like others mentioned this gets messy during shipping so definitely order it separately if you can. You don't want to have other items in the same package.

Stopped the leak

Used a half a tablet to seal the overflow tank on my generator. Side note. The packaging sucks. Had stop leak powder all over everything else in the order.

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.

Good price but only worked a few days
