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!

Worked great and great price

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.

It didn’t completely stop the leak but slowed it down dramatically and my car is no longer over heating.

Unfortunately this did not work.for me. I had a completely empty radiator. Put a new thermostat in and did a full cycle and purge. Have a small leak at the top near the upper radiator hose. This product stopped it for a day. Leak is back.

I have a small coolant leak on my Jeep — not huge, but it was dripping. I read a lot of reviews. Many people said this product does nothing, especially on European cars. But I noticed that most of those people had big, serious leaks. Then I found one review from another Jeep owner with a small leak, just like mine. It worked for him. So I decided to try it. It worked for me too. My small drip stopped completely. My honest opinion: If you have a small leak (seepage, not a gusher) — this will probably fix it. If you have a big, active leak — don't waste your money. Fix the real problem. I'm happy with the product. It saved me time and money. But you have to be realistic about what it can do.

I had a hairline crack in a radiator on my dump truck and used this and It pretty much stopped it in a day. I was adding a gallon once a week and havent added any at all in 2 weeks.

I edited this product to my radiator in my Mazda 6 two months ago in mid-January, because I had a very slight leakage in my heater core or somewhere which was causing my windows to fog up, I started with one half of the bottle, it helped a little, then I Added most of the make remaining portion, and is eliminated the window fogging within three weeks. As of today which is two months later my heater core is completely plugged up and I get no heat. I called the company and spoke to a very nice gentleman named Sean who suggested various remedies such as burping the system to possibly correct the problem followed by using a cleaner flushing product, followed by replacement of heater core or whatever is necessary. He was trying to attribute this pluggage to scale and rust in my radiator of which there is none. That product says unconditionally guaranteed not to Muck up your radiator, I will be taking it to the shop to have them do the necessary repairs and will be contacting bars to pay for it. However I am sure from my conversation that they will be some problem inasmuch as they want me to ship them the parts and the liquid contents of my Radiator for their examination and determination as to whether they have any responsibility in this more to follow just be aware that this happened to me

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.
