1186 Liquid Aluminum Stop Leak - 16.9 oz | Safely and Easily Seal Leaks in Plastic, Aluminum and Metal Radiators, Heater Cores, Gaskets, Freeze Plugs

Looks like it worked. No more leaks.

Stopped leak in the engine block. Good product. Bought 2nd time and used in lexus as a preventive measure for any future leaks or problems.

IT WORKS!! stops small leaks in any type of radiator with minimum effort, just follow the directions but don't forget to drain some coolant before adding the product (about 1 litre) then top up later.

يعمل على اغلاق الشقوق في دورة التبريد لكنه لا يغني عن الاصلاح اذا كنت تريد تأجيل الاصلاح استعمله لكن بالنهاية عليك اصلاح مكان التسريب

Good product

Fixed my car leak

Doesn’t work

100 %100 Ok

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.

IT REALLY WORKS! Hello ya'll, I was faced with a 750 dollar repair bill for a leaky radiator, Not a small leak either, within 10 minutes the radiator was 75% empty, so with that being said I followed instructions and within 30 minutes, NO MORE LEAK! So If you find yourself in the same boat I was in, I'd say give it a shot.

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.
