Bar's Leaks Cooling System Radiator Stop Leak 16.9 oz.

I just bought the Bar's Leaks Liquid Aluminum Stop Leak and I’m truly sastified. After noticing a coolant leak from my car on my driveway and when I got to work, I was afraid that i might break down on the highway going to work or going home from work. At first, I was skeptical about using a stop leak product since I’ve never used one before nor did I hear anyone give me feedback about their experience with any leak but this one honestly exceeded my expectations. I am 100% happy with the results, I haven’t seen any leaks. I will top my coolant reservoir with coolant and see if the reservoir itself will decrease in coolant since I haven’t seen any drips under my car. It was straightforward, add the bottle into the reservoir since I didn’t have access directly to the radiator on my car. It has instructions on the bottle on how much and where to add the liquid to. My engine temperature is normal when driving and I’ve never seen it go up ever since adding this leak liquid. I can say I’m satisfied and for reference, I added full bottle into my reservoir and my vehicle is a fairly newer Jeep Grand Cherokee!

This worked immediately. Quoted $1600 for repair. If this holds its worth every penny.

I used another product that worked for 18 months. This product stopped the leak for 11 months but it cost a little less. Much better than a $1500 repair.

It works great stopped my leak right away

Yeah I think you can get some years ago my pickup truck started spraying coolant all over the place under the hood period I was traveling, and I was not in a position to replace the water pump. So I went to Walmart and looked at all the radiator stop leaks they had there. This was the only one that offered a money back guarantee. I did not care about the money back guarantee, but it made me think that they must really believe in this product. I told my son that I had been using radiator stop leak products for over 50 years, and they had never really worked. So he asked me why I was doing it now. I said because I didn't have any other choice. And then, to my utter astonishment, this product worked. After a few minutes, all the water spraying under the hood stopped! This is years later, and I still haven't replaced my water pump. I have had to refresh this product once or twice by adding more to my cooling system, but who cares. I always travel with a full bottle of this in the truck somewhere!

I used this on my older Pontiac grand prix sedan. I placed it in my radiator hoping it would seal a leak coming from my radiator. After a week of driving in town and just enough to prevent the car from getting to hot, I still noticed that the product was not sealing the leak to feel satisfying and safe. If it would have sealed the leak after two applications withing the first few days, I would have felt the seal was solved. I feel my older car was just in need of a new radiator and as good as this product may be, it just did not do it for my car. I feel better knowing I have a new radiator in my car, but this product may help your situation. You can't go wrong with a guarantee on the bottle.......

Absolutely fixed my leak. Incredible stuff. I can see where the hose was cracking and this stuff filled it perfectly. Follow the bottle instructions and you will be good to go.

save your money and buy a new radiator. i put 5 bottles in over the course of 3 weeks i started out loosing only about a half gallon a day to 2 1/2 gallons every trip to the store that was 3 miles away. it make my leak worse. so don't waste your money on buying something that does not work. so i really had to replace my radiator after using this product. there went $1000 for a new one.

I’d say it worked great, I did something very stupid, I had my van idling on my driveway for about twenty minutes or so and my neighbour saw smoke coming from it and alerted me, most of the fluid leaked out of the radiator and in the process it sprung a couple of leaks, went and checked on line with my very good friend the one and only Scotty Kilmer and Barr,s radiator stop leak is what he swore by, no regrets using it, most of the leaks are gone just a minor drip from what I believe is coming from the drain plug, glad I used Barr’s Stop Leak

SI ME FUNCIONO !! LO RECOMIENDO.

Looks like it worked. No more leaks.

Had a minor leak coming from the bottom of my car radiator. Watched the video from the makers and used half a bottle for a 2009 Nissan Sentra and 3 days later no leak visible and the overflow bottle not drained, fingers crossed. Update: 5 months on and no leak. Highly recommend for minor leaks.
