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!
