Includes Xtreme Cool to stop overheating and lower water temperature Guaranteed to safely and easily seal leaks in plastic, aluminum, metal (copper/steel) radiators, heater cores, gaskets, and freeze plugs. Will not damage your cooling system and requires no drainage. Use on all types of conventional or long life coolants including yellow, orange, pink, red, blue, purple, green silicate base & non-silicate base (OAT/HOAT) 50-50 mix antifreeze and/or water. Seals instantly on most vehicles Review: 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 Review: 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! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002696FA2 | | Amazon Bestseller | #507,526 in Automotive ( See Top 100 in Automotive ) #340 in Automotive Engine Coolants | | Customer Reviews | 4.3 4.3 out of 5 stars (3,481) | | Date First Available | August 28, 2012 | | Is Discontinued By Manufacturer | No | | Item model number | 1186 | | Product Dimensions | 4.57 x 7.62 x 16.76 cm; 362.87 g | ## Product Details - **Brand:** Bar's Leaks - **Item Weight:** 363 g - **Item dimensions L x W x H:** 46 x 76 x 168 mm - **Number of Packs:** 1 - **UPC:** 046087011867 ## Images ![Bar's Leaks 1186 Liquid Aluminum Leak Proof 16.9 oz - Image 1](https://m.media-amazon.com/images/I/710LVf+KX5S.jpg) ![Bar's Leaks 1186 Liquid Aluminum Leak Proof 16.9 oz - Image 2](https://m.media-amazon.com/images/I/71l9W0HcjyL.jpg) ![Bar's Leaks 1186 Liquid Aluminum Leak Proof 16.9 oz - Image 3](https://m.media-amazon.com/images/I/41X0xUy+9EL.jpg) ## Questions & Answers **Q: My radiator leaking from the seam. Slightly overheating. Will this seal at the seam?** A: It should,depending on how big the leak/crack is,the one on my semi truck was dripping big,half a gallon a day,I was worried bc that s a $2,000.00 repair,I bought it not expecting any results,since I had previously used Bars leak (the small silver bottle) and didn t work,so this was a prayer and a last hope, 5,000 mls later and not a leak,not extra coolant added,it is liquid aluminum,so it bonds to wherever the leak is and forms a sealing coat...I think of it as welding from the inside...I hope it works for you as it did for me,it really was an answer to prayer...I know I m a bit dramatic but it was.PS,try to follow recommended amount or as close as recommended,not much less and not much more,I used 2 bottles on a 11 gal radiator.God bless. **Q: can it be used in a Tahoe plastic tank** A: i used it in my volvo which has a plastic expansion tank and no problems. it won't fix big leaks but if you're losing just a little coolant over time and can't find the leak this is the stuff to use! **Q: My volkswagen golf gti 2018 doesn’t have a radiator cap can i still put it in a coolant reservoir to seal my radiator leak?** A: If direct access to radiator is not available, install in overflow tank. Please ensure overflow is pressurized before adding. DIRECTIONS Allow engine to cool. Make sure engine is cool enough so radiator cap can be safely removed. Shake well. Pour Bar’s Leaks Liquid Aluminum directly into radiator. One bottle treats systems up to 4 gallons. Use 1/2 bottle in 3 and 4 cylinder engines. TIP: If direct access to radiator is not available, install in overflow tank. Fill radiator and overflow tank to proper level and reinstall radiator cap. Drive/idle engine for 15 to 20 minutes. If leak continues, second application may be required or mechanical attention is needed. For severe leaks, like a blown head gasket, it is recommended to use Bar’s Leaks Head Gasket Fix or Blown Head Gasket Repair. Leave Bar’s Leaks Liquid Aluminum in cooling system for continued protection. If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website. **Q: will this work on the head also?** A: Try it...it's inexpensive. Whether it works depends on the specifics of your problem. I tried it on a 4 cylinder BMW with a new head and profile gasket and a slow leak. It worked great. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***I on May 29, 2025* 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 ### ⭐⭐⭐⭐⭐ Review *by A***Q on January 13, 2025* I just bought the Bar's Leaks Liquid Aluminum Stop Leak and I’m truly sastified.
