Review on 🔧 Effective 16.9 oz Gray Bar's Leaks 1186 Liquid Aluminum Stop Leak for Superior Performance by Douglas Hall

ONLY suitable for stopping coolant leaks, including large ones. You just need to pour the coolant directly into the coolant hose and tank as instructed. This solution is liquid and metallic grey. It will stop a coolant leak and I've used it on several cars I've owned over the years. However, if you have a bad temperature sensor that is resetting your coolant level, this won't help you. You need to expose it and make sure it's a leak and not just a bad sensor, bad temp cap, blown gasket, or radiator issue. It's easy to spot by watching LOTS of YouTube videos, LOL. Obviously this is the cheapest option but of course I would only recommend it if you are trying to fix/fix a leak and have confirmed it is 100% a leak. Hope that helps :)
