Review on 🔧 Bar's Leaks Liquid Aluminum Radiator and Heater Core Stop Leak - Ultimate 6 Pack (1186-6PK): Save your Vehicle's Cooling System! by Matt Mosley

This product will repair many leaks. It's been around for years. I once bought a car 20 years ago which they gave away because it had a water leak and they thought the head bolts were broken or the gasket was bad. I added some of this and eventually fixed the leaks and drove this car for another 5 years. Don't let the fact that you can fix any leak with it fool you. If it's a small leak and doesn't push all of the water out of the tank with steam or whatever, just a drip, this will work fine. If it's a head gasket and you have steam coming out of your tailpipe and you can't keep water in it, don't think that buying this bottle will solve all your problems. Most of these products are not designed to be THE TREATMENT. They are forced to work as a makeshift association. If the radiator or other hose is rotten, it's best to just fix it. All of these products say they'll give you your money back, but I've never seen that before. I don't see the point in driving back and forth to the dealership and saying, yeah, it didn't work, give me back my $4, and in the meantime you'll burn ten dollars' worth of gas. We used to use these products for prevention. Use it in a good system and then if your radiator hits a rock or something and it drips it will do fine for that. Forget internal engine problems.
