It Works!
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.

Timely delivery and excellent response
Excellent response and timely delivery on the behalf of the seller. I appreciate the extra touch of adding the automotive air fresheners for my vehicle. Overall, the volume purchase was definitely worth the price + shipping adder, and I'll be sure to consider them for future purchases.

Good tablets to carry and easy to pack and store.
I’ve used Bars leak brand over the years for a couple of emergency's. They always performed as intended. I bought these to carry in my tail bag on my adventure bike. The last thing I need is a leaky radiator or cracked radiator out in the middle of nowhere. I used them years ago in a Jeep when a leak was developed on a trail. Crumble them up, add water and you’re back in business. I bought these as a preventative measure and would recommend them to anyone venturing off the beaten path.

Works great for certain types of leaks
Bar's Leaks 1177 Radiator Stop Leak Tablets may work for certain types of radiator leaks, but it will not seal plastic tank or rubber seal leaks. The radiator in my GM vehicle was leaking where the plastic tank is crimped onto the aluminum radiator core, and since the job to replace the radiator takes about 5-6 hours, I thought I would give Bar's Leak a try. Much to my dismay, it did not perform as I hoped it would. Lesson learned.
