XADO ATOMEX Stop Leak Radiator Coolant Additive - Repair Seal, Restore Radiator Fluid Fix and Prevent Future Leaks (Bottle, 250 ml)

Got the wrong product at first but they sent me correct one but it's a pain to have to return the one you got sent incorrectly by shipper. I shouldn't have to do that when it was there mistake. Product really works though my leak stopped about 45mins after putting product in my radiator. Definitely recommend for small leaks

Had a drip in the radiator on my daughters car , followed directions and this didn’t work at all .

good quality, seems to work for small leaks

I just put the radiator stop leak in the other day did all directions to a T. So far so good not one leak and the engine is now running cooler than before.

I'm waiting for the result

I have this handy as our two cars are older. So far, they aren't leaking but I wanted to keep this around just in case. I've had good fortune with things like this, but there are some caveats. First, I would only use this on an older radiator as a way to extend it's life until I can get a replacement. I would not use something like this in a newer radiator. Second, even though it says it can be used as a preventative measure, I'd avoid it. It's something I'm uneasy about. I only add things like this when it's absolutely necessary and there's really nothing to lose.

Radiator still leaks

Good product
