      I was a skeptic, now I'm not

      1 of 2 people found this helpful

      Always a skeptic, I had a 1989 Mercedes with a steady stream coming out of the radiator when running and a steady seepage when sitting. $200 for a new radiator or $8 for Bar's. For $8, what the heck. It worked!!!!! Not sure about long term but absolutely NO leak at all. Just make sure you run the engine for 30 minutes, don't skimp.

      Pros: Easy to use, it works

      Cons: None, didn't use it sooner

      Bar's Liquid Aluminum Cooling System Stop Leak

      0 of 1 people found this helpful

      My 2003 Buick Lesabre Limited with the 3.8L engine began using coolant, but I couldn't find a leak. No steam or liquid drips anywhere. Then I looked inside the coolant recovery tank and saw some bubbles coming from the radiator which indicated a blown head gasket, or possibly a warped head.

      Figuring that this was going to be an expensive repair, I tried adding a 16.5 Oz. bottle of the Bar's Liquid Aluminum Stop leak since I didn't have anything to lose.

      After siphoning out enough coolant from the radiator to make room to add the Bar's Liquid Aluminum Stop Leak, I drove about 30 miles to warm up the engine and circulate the Bar's throughout the cooling system. At first, I was disappointed because the bubbles were still there, so I parked the car for the night. The next day I drove about 30 more miles and checked the coolant recovery tank for bubbles, but could not see any more bubbles. After driving an additional 30+ miles, I again checked the recovery tank, but there were still no bubbles. At this point, I'm hoping the internal coolant leak has been stopped by the Bar's Liquid Aluminum Cooling System Stop Leak.

      Pros: Works GREAT, and FAST

      Had a radiator leak, now I don't.

      4 of 5 people found this helpful

      There were more than just this product that I could of chose from. But, since I have used Bar's products before and all went well with those, I decided to go with Bar's again. It does say on the label that it stops leaks instantly, so that's what I expected. Didn't happen. I gave it another day to let it settle and see what happens. The instructions say that if it does not work with the first application, then use a second. I almost went to get another bottle, but, by the next day, the leak had stopped. So now 2 days later and still no leak. Hopefully this is a permanent solution. I give this product a big thumbs up!

      Pros: Sealed up the leak, and the formula also helps keep fluid cooler than usual.

      Cons: Advertizes that it stops leaks instantly. Not in my case.
