It's been about one month since I applied the treatment to my 1980 yanmar tractor. The tractors engine block had a significant crack in it that had been brazed together. The treatment has reduced leaking from block. So far it's working as expected!

I have a 2016 malibu with a 1.5 turbo with 91000 miles. I was getting antifreeze vapor out the tailpipe upon startup. Obvious head gasket leak although not a bad one as I have only lost half a gallon of antifreeze over the last five months. used the bars fix product and it worked. 1500 miles later and still no gasket leak. Will see how it does longer term.

I wasn't expecting it to work so well. I struggled with overheating and non-working cooling system for a year and a mechanic suggested I put the sealant in. He did suggest which brand but Bar's Leak seemed like the best one. After running it for 15 minutes it seemed to work properly. It has been working for several weeks now like it should. Amazing stuff!

I can't speak for every situation but this worked perfectly for me. My Dodge caravan had been overheating, blowing out white smoke and eating up coolant. The coolant wasnt leaking onto the ground and I was pretty sure it was leaking out of a crack somewhere on the engine.I made sure oil wasn't leaking anywhere in the system. This is important. Look online to see how to check for this.I carefully read the instructions, poured it in, let it run for 15 minutes with the hot air on full blast. I then let it sit for a couple hours before turning it on again.After that the white smoke stopped coming out and coolant was staying in the reservoir. It worked for me. Again, it doesn't work for every situation but it cleared up my issue and even the engine light went back out.If you have no other options or the money to repair the engine this might give your car some more time. It's just a patch but it will keep my van running awhile longer.

I had the radiator, thermostat and new fan installed on my vehicle but something was still off as it would overheat in high temperatures outside. I read reviews about people saying not to put additives in your radiator if it is the head gasket or any other leak but I'm glad I actually used this product! Since I used this my car stopped overheating and it runs so much smoother. Love this product! It saved me hundreds of dollars. It actually worked great for my situation

I was skeptical but this stuff really worked. My Prius doesn't have a radiator cap (Surprise!) so I poured half the bottle into the coolant reservoir. Next problem was you can't really get the Prius to idle for 15 minutes with the engine on, so I just drove it around. A few days letter the check engine light shut itself off.
