Smoke from the engine?

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!

I bought this for my 2002 Dodge Durango which appeared to have a small leak near the bottom of the radiator. I noticed I was repeatedly adding a little coolant to keep the overflow tank measuring stick up to snuff. I didn't notice any major spotting, but in the past week had seen some coolant which had dripped under the engine. All the hoses, etc. checked out fine, but the leak had become noticeable. I bought one bottle and added it to the car. The bottle says to add it to the radiator, or lacking direct access through a pressurized cap to add through the overflow reservoir. I shook the bottle well. The fluid is a somewhat thick consistency. I followed the tips of a few people on-line and added most of the bottle in through the pressurized cap, then added less than a quarter of the bottle into the overflow. I capped the radiator and then ran the car for about 45 minutes. The bottle said 10-20 minutes but........ Anyway, the leak appeared to immediately stop. It has been over a week and I have not had to top off the coolant. I will update this review should anything change. Overall, reliable product from my experience.

There was a problem with how I was able to get it in my radiator, other than it works. Here was the problem, not enough room for the product to get into the radiator. I put it in the recovery container. The whole reason I used Bar's Leak is because the Radiator was leaking. After checking it out more I went to have the Radiator replaced but the people who worked on it told me that I needed to have the rad. water pump and everything else replace dealing with the system. This Bar's leak product works to coat the entire system not just the Radiator. So that's why the person who told me it was going to cost $2500 was wrong. I trust Bar's Leak, and when needed, I will Trust Them again.

It works great stopped my leak right away

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

I have used Bar s head gasket sealer before with success on my old tacoma. Used this on my acura rsx had original radiator with 300k. The leak was coming from the top of the radiator . A few inches i tried to patch it with Jb weld and added this stuff. Worked for about a week. Did slow things down but still leaking coolant . Would only recommend on putting in old cars. If not replace your radiator. I end up replacing my radiator this stuff needs to be flushed out now. Little metal flakes in coolant

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!

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

جيد

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.
