Ratings & Reviews for Bar’s Leaks Bars Leaks Liquid Aluminum Radiator and Heater Core Cooling System Radiator Stop Leak 16.9 oz

Excellent

I used it on a couple of cars, and it worked very well. I recommend it 100%.

"The Hail Mary that actually stuck: saved me a tow

I noticed a steady drip coming from my radiator last week, right as the heat and humidity began to hit in Texas.....after getting a quote on a full radiator replacement that made my eyes water, i decided to try a bottle of Bars leak liquid aluminum as a last ditch effort before committing to the shop......after about 20 min. it worked like a charm and i recommend it essential for anyone trying to keep an older drive on the road without breaking the bank

Works awsome

I was haven trouble with a leak when a friend introduced this, I was hesitant because I had tried different brands to no success, but he swore on it and it worked fast and its held for 6 months and going! Truly a great product at a great price!

Surprised me.

I had a large coolant leaf in my thermostat housing. I used this product and was genuinely suprised by how well it worked. Sealed the leak within minutes!

Works like a charm

I bought this had a small leak under the hood it would be constant drops but with all these plastic covers over engines these days I couldn’t see it so I added this slowly to the radiator while car was cold and in less than 10 mins I saw the drops stop really happy with the results :)

Worked Amazing!

I had a persistent coolant leak, even after replacing all the parts, there was a minute leak which I couldn't figure out for years now. I used Bar's Leaks Liquid aluminum and it fixed the issue immediately. What was amazing Is that I only used about a third of the bottle and it worked right away. I would certainly use this again and highly recommend it to anyone having the same issues.

Stopped the leak

I added this to my radiator yesterday and took it for a 1/2 hour drive around town. When I got home I couldn't find the leak. The antifreeze smell was gone where it had been leaking on the manifold. My Dad was a mechanic and always said Bar's was the only leak stop he would recommend and now I see why.
